Report privately through GitHub's security advisories rather than as a public issue, so a fix can exist before the details do.

Expect an acknowledgement within a week. If a report is a real vulnerability, the advisory will name the affected versions and the release that fixes it.

This library builds command lines for tmux and parses what tmux prints, which is where its interesting failure modes live:

• Argument injection. A session, window, or pane name that escapes its argument and becomes a separate tmux command.
• Parser failures on hostile input. Output from a tmux — or from something pretending to be one — that crashes, hangs, or corrupts state rather than being rejected. The fuzz tests cover the known shapes; anything they miss is worth reporting.
• Leaking a socket to the wrong process, or reaching a tmux server the caller did not name.

• tmux's own vulnerabilities. Report those to tmux. This library is a client.
• What a caller does with a pane. Sending arbitrary text to a shell is the purpose of SendTextAsync, not a flaw in it. A caller passing untrusted input to it has an untrusted-input problem.
• The MCP server's permissiveness. LibTmux.Mcp gives an assistant the ability to run commands in a terminal. That is what it is for; run it where that is acceptable.

While this is alpha, only the latest prerelease is supported. Fixes go into the next version rather than into patches of earlier ones. A published version is never deleted, so an old alpha stays installable and stays unfixed — pin deliberately.

release.yml builds, inspects and publishes every release from a v* tag, through nuget.org trusted publishing rather than a stored API key. It attests each package twice: as built, and as nuget.org serves it with its repository signature, which is the file a restore downloads. NuGet keeps that file under ~/.nuget/packages, so with VERSION set to the version you restored, check it against the workflow and commit that produced it:

$ gh attestation verify \
    --repo libtmux/libtmux-dotnet \
    ~/.nuget/packages/libtmux/"$VERSION"/libtmux."$VERSION".nupkg

Each release also carries a CycloneDX SBOM of the packed artifacts, attached to its workflow run.
