docs(security): document private vulnerability reporting by sunny-wego · Pull Request #86 · wego/cli

sunny-wego · 2026-09-22T03:25:50Z

Addresses the reporting half of REPO-11 (wego/foundations#221).

SECURITY.md told reporters that email was the only channel we monitor. It
isn't, and hasn't been since PVR was enabled. This fixes that, and softens an
acknowledgement deadline nobody owns.

Scope of the change: the Reporting a vulnerability section only.
Supported versions, Scope and How releases are protected are byte-identical
to main. No bug bounty added.

1. Email was not the only channel

The file opened with "Email security@wego.com. That is the only channel we
monitor for security reports." That is false:

$ gh api repos/wego/cli/private-vulnerability-reporting
{"enabled":true}

There is a Report a vulnerability button on the Security tab, and a reporter
who trusted that sentence would not have used it. The section now names both
routes and prefers the Security tab, with the reason stated: a report there can
be taken into a temporary private fork and fixed there. main is public, so
a vulnerability fixed in the open is disclosed by its own diff before the fixed
binary reaches a user, and nothing else in this repository closes that window.

Deliberately not claimed: PVR is not how an advisory gets published — that
always worked, and the file says so explicitly so nobody reads the preference as
a requirement. security@wego.com stays documented.

2. Every report is welcome — no attacker triage asked of the reporter

The policy does not sort attackers into external and insider, and does not
ask a reporter to decide which side of that line their finding falls on. That is
our triage question, not theirs, and putting it in front of them mostly produces
reports we never receive. The file says so plainly:

Report anything you think is a security problem. We would rather look at a
report that turns out to be nothing than miss one because you were unsure it
counted.

3. The five-day promise — option (b), softened

No owner is named and no placeholder is left, so there is nothing to fill in.
REPO-10 closed as accepted without an owner and none is coming, so option (a)
would have meant publishing a control that does not exist. The file still
commits to acknowledging and keeping the reporter informed; it just does not name
a date. That matches what CONTRIBUTING.md:325 already says about issues and
pull requests. The file does not explain why there is no date — that reasoning
is internal and stays in this PR.

What is NOT in the published file — read this before closing REPO-11

REPO-11 as written asked for the threat model to be written into
SECURITY.md. By maintainer decision it is not, and neither are the audit's
decision records. The published policy covers reporting only. REPO-11 should
not be closed as "threat model documented in the repository" — it is
documented here, in this PR, and wego/foundations#221 is the right home for it.

Two consequences worth recording:

The external / insider axis and its carve-out (the coerced, the negligent,
and an account compromised through a person rather than a token) appear nowhere
in the repository. That carve-out is what stops a person-reachable finding
inheriting an insider disposition, and REPO-8 depends on it.
The pre-existing "Findings that require an attacker to already control the
user's machine or their account" bullet is restored unchanged. It only
ever contradicted the insider carve-out, so with the carve-out gone there is no
contradiction left to reconcile.

The decision record, for wego/foundations#221

Kept here so it is not lost. Six dispositions:

Finding	Disposition	Rationale
REPO-10	accepted	No incident-response runbook: no named triage owner, no severity rubric, no credential-rotation procedure. The compensating sweep needs org-admin scope `GITHUB_TOKEN` does not have, and the credentials that would bridge it (an org PAT, an admin-scoped App) are a worse standing exposure than the gap.
ORG-7	accepted	No audit log. Not available on this GitHub plan.
REPO-9	skipped	Provenance largely redundant with cosign and the Fulcio SAN; the available SBOM would describe 16 of 100 packages.
REPO-1	parked	An admin merging without review. The default branch ruleset requires a PR and has an empty bypass list (`bypass_actors: null`), but an account that can delete the ruleset need not merge past it.
ORG-2	parked	109 collaborators. Deliberate grants.
REPO-8	parked	Push-protection bypass has no approver. Reachable through a person, which is why it could not take the disposition REPO-1 and ORG-2 took.

Decision B: ten live findings were put to the question can a person outside
the wego organisation reach this? Three survived; seven were deprioritized,
not accepted — REPO-1, REPO-7, REPO-8, ORG-5, ORG-6, ORG-2 and ORG-4's ruleset
half. They remain live. This narrowed prioritisation, not scope. The cost,
stated plainly: an attacker who is already inside meets less resistance than
they otherwise would.

Two premises in the audit worth checking

Both are written in the file using the audit's own wording, by decision. Both are
narrower in reality:

"edge-cli publishes on every merge to main." Its push trigger carries
a paths filter (.github/workflows/edge-cli.yml:31-42 — src/**,
scripts/**, build config), so it publishes only on pushes touching the CLI.
The disclosure-window argument is unaffected: a vulnerability fix lands in
src/**, exactly what the filter matches.
"A report notifies all ten repository admins." There are ten admins, but
GitHub notifies admins and security managers only if they watch all activity
or subscribe to Security alerts and have notifications enabled
(configure,
manage).
The durable property is the visible triage queue, not the notification.

`SECURITY.md` said email was the only channel we monitor. Private Vulnerability Reporting has been enabled on this repository since 2026-09-22, so that sentence was false and pointed reporters away from the better route. The Security tab is now the preferred channel, with the reason stated: a report there can open a temporary private fork. `main` is public and `edge-cli.yml` runs on every push to it, so a fix developed in the open is public the moment it merges, while the people on `cli/stable` wait for a manual promote. The private fork is the only thing here that closes that window. Mail still works and is still documented. PVR is not what publishes an advisory, and the file does not claim it is. Adds a *Threat model* section for the axis the 2026-09-22 audit triaged on, which appeared in no file in this repository. External attackers are in scope, including one holding a stolen credential. Insiders acting deliberately within their granted access are out. The carve-out is explicit and narrow: the coerced, the negligent, and an account compromised through a person rather than through a token all stay in scope. Without that written down, four accepted risks read as ignored gaps. The section names them as decisions: no incident-response runbook, no audit log, an admin merging without review, and the size of the write-access list. The pre-existing "already control the user's machine or their account" bullet contradicted that carve-out read literally, so it is rewritten to exclude only findings that assume the access they are about, and to say that *how* the account was taken is in scope. The five-day acknowledgement promise is softened rather than owned. No triage owner exists, none is coming, and printing a deadline nobody owns is worse than saying we cannot promise when — which is what `CONTRIBUTING.md` already says about issues and pull requests.

Two claims in the new text overstated what is checkable, and a security policy is the wrong place for that. edge-cli.yml does not run on every push to main. Its push trigger carries a paths filter (src/**, scripts/**, the build config), so it builds only when a push touches the CLI itself. That is still what a vulnerability fix touches, so the disclosure-window argument holds, and stating it precisely makes it verifiable against the workflow rather than merely plausible. PVR does not guarantee a notification to all ten admins. GitHub notifies repository admins and security managers only when they watch all activity or subscribe to Security alerts and have notifications enabled, so the recipient set is per-person preference, not a promise this file can make. The durable property is the queue: a report lands as a triage advisory on the Security tab that every admin can see. The same claim was repeated as the hedge for having no response-time owner, and both instances are fixed. Swept the rest of the file for the same shape of unverifiable absolute and found no others.

@coderabbitai > [reply to @coderabbitai review]

Fixed both at 14fac5a. Both were genuine overstatements in sentences I wrote: the edge-cli.yml paths filter (SECURITY.md:15-18) and the PVR notification guarantee (SECURITY.md:24-27, plus the repeat you flagged at :41-43). I also swept the rest of the file for the same shape of unverifiable absolute claim and found no others, so the class is closed rather than just the two instances.

@sunny-wego Confirmed. Commit 14fac5a scopes the edge-build claim to the workflow paths filter. It also replaces the notification guarantee with the visible triage-advisory queue. Both review findings are addressed.

Learning: In the `wego/cli` repository, `.github/workflows/edge-cli.yml` publishes an edge build only for pushes to `main` that touch CLI-related paths, including `src/**`, `scripts/**`, and build configuration. Do not describe it as running on every push to `main`.

Learning: In `wego/cli` SECURITY.md, GitHub Private Vulnerability Reporting reports appear as triage advisories on the Security tab that repository administrators can see. GitHub notifications depend on each administrator's security-alert settings, so SECURITY.md must not guarantee notification delivery to all administrators.

…rding Rewrites the threat-model section against the audit's full triage, which turns on two decisions rather than one. Decision A is unchanged in substance: external attackers are in scope, including one using a stolen credential; insiders acting deliberately within their granted access are out; and the exclusion does not reach the coerced, the negligent, or an account compromised through a person rather than a token. Decision B was missing entirely. Later the same day the working question became blunter: can a person outside the `wego` organisation reach this? Ten live findings were put to it and three survived. The other seven were deprioritized, and the section says plainly that deprioritized is not accepted, that those findings are still live, and that this changed what we work on first rather than what is in scope. It also states the cost, because a reader who finds seven parked findings and no reason will assume they were missed: an attacker already inside meets less resistance than they otherwise would. The decision table now carries all six dispositions with their real categories. REPO-1 and ORG-2 are parked rather than accepted, which the previous version had wrong, and REPO-9 (skipped) and REPO-8 (parked) are added. REPO-8 is called out as the finding that shows why the carve-out earns its place: a delegated bypass with no approver is reachable through a person, so it could not take the disposition REPO-1 and ORG-2 took. The pre-existing "already control the user's machine or their account" bullet is reconciled rather than contradicted, so the file does not both exclude and include an account compromised through a person. The five-day promise is softened rather than owned. No owner exists and none is coming, so the file commits to acknowledging and keeping the reporter informed without naming a deadline. This also restores the audit's own wording for two claims that commit 14fac5a had narrowed: that `edge-cli` publishes on every merge to `main`, and that a report notifies all ten repository admins. Both were narrowed because the workflow carries a paths filter and GitHub's notification is conditional on each recipient's alert settings. Keeping the audit's wording is a deliberate maintainer decision, not a regression. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JQc26erK3dPsDMmqX56bzb

Removes the audit's internal decision record from the published file. The six dispositions, the finding identifiers, the count of findings put to the organisation-membership question, and the note about what parking them costs were all written for the people who made those decisions, not for someone deciding whether to report a bug. They belong in the audit's own tracking issue, and they are recorded in this pull request instead. What survives is what a reporter acts on. Where to report, and that the Security tab is preferred because a fix can be developed in a private fork before the diff discloses it. What to include. That there is no bounty. That we will acknowledge and keep them informed without promising a date. The scope question a reporter actually has is "will you take this?", so the attacker model is merged into Scope rather than standing as its own section. External attackers are in scope, including one using a stolen credential, which is an external attacker wearing an insider's identity. An insider acting deliberately within granted access is out. The exclusion does not reach the coerced, the negligent, or an account compromised through a person rather than a token, and the section says so as an invitation: if you can show how an outsider reaches an insider's access, we want the report. The pre-existing "already control the user's machine or their account" bullet contradicted that carve-out read literally, so it is rewritten in place to exclude only findings that assume the access they are about. Supported versions and How releases are protected are untouched. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JQc26erK3dPsDMmqX56bzb

The policy no longer sorts attackers into external and insider. Asking a reporter to work out which side of that line their finding falls on puts our triage question in front of them, and the likely outcome is a report we never receive. Report anything you think is a security problem, and the file now says so in as many words: we would rather read one that turns out to be nothing than miss one because you were unsure it counted. Removing the distinction also removes the contradiction it created. The pre-existing "already control the user's machine or their account" bullet only conflicted with the insider carve-out, so with the carve-out gone the bullet is correct as it was originally written and is restored unchanged. Scope is now byte-identical to before this branch. What remains is the reporting change itself: both channels documented with the Security tab preferred, why the private fork matters here, that it is not what publishes an advisory, and an acknowledgement commitment without a date attached.
