Updates tailwindcss from 4.3.1 to 4.3.3

Release notes

Sourced from tailwindcss's releases.

v4.3.3

Fixed

• Support --watch --poll[=ms] in @tailwindcss/cli when filesystem events are unreliable or unavailable (#20297)

• Prevent Preflight from overriding Firefox's native iframe:focus-visible outline styles (#20292)
• Ensure theme('colors.foo') in JS plugins resolves correctly when both --color-foo and --color-foo-bar exist (#20299)
• Ensure fractional opacity modifiers work with named shadow sizes like shadow-sm/12.5, text-shadow-sm/12.5, drop-shadow-sm/12.5, and inset-shadow-sm/12.5 (#20302)
• Parse selectors like [data-foo]div as two selectors instead of one (#20303)

Updates @xmldom/xmldom from 0.9.10 to 0.9.12

Release notes

Sourced from @​xmldom/xmldom's releases.

0.9.12

Commits

Fixed

• Security: parsing a deeply or repeatedly namespaced document no longer consumes quadratic memory; the in-scope namespace map is inherited through the prototype chain instead of being copied for every prefix-declaring element (O(N) instead of O(N²)), preventing a denial-of-service reachable from DOMParser.parseFromString with default options. Serialized output is byte-identical. GHSA-965w-775f-mr7g
• Security: attribute de-duplication during parsing is now O(M) instead of O(M²); the NamedNodeMap parse-time dedup path uses a null-prototype membership index, so a well-formed document with a hostile number of duplicate attributes can no longer wedge the parse. Attribute order and duplicate resolution (last value wins, first position kept) are byte-identical, preserving the XML no-duplicate-attributes well-formedness constraint. GHSA-8344-3jmq-59r6
• Security: HTML raw-text parsing no longer amplifies output on a missing or case-mismatched closing tag; the closing tag is matched case-insensitively per the WHATWG HTML RAWTEXT end-tag rule and a missing closing tag is handled explicitly, preventing a denial-of-service. Output for well-formed input is unchanged. GHSA-6mj3-qw4j-hgrw
• Security: malformed-input recovery is now linear instead of quadratic — the malformed tag-name scan terminates at an embedded <, and Node.prototype.normalize() merges adjacent text nodes in O(K) instead of O(K²) (also reachable programmatically), per normalize() in the WHATWG DOM spec. DOM output is unchanged; only the reported error text differs. GHSA-93r5-fhx6-vmg9
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now rejects a DocType name that is not a valid XML Name, throwing InvalidStateError — matching the sibling publicId/systemId/internalSubset checks and preventing XML injection via DocumentType.name. GHSA-27p8-2357-5qqv
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — preventing PI-target injection via >, ?, or whitespace. GHSA-c7q8-3ch8-vqpv
• Security: Document.createEntityReference() now rejects an invalid XML Name at creation, and XMLSerializer.serializeToString() under { requireWellFormed: true } validates an EntityReference nodeName as an XML Name, throwing InvalidStateError — preventing XML injection via an entity-reference name. GHSA-6gmq-8vp8-gcm6
• Security: the requireWellFormed serializer's element- and attribute-name validators no longer treat an interior line terminator as satisfying the name anchors, so a name containing a line terminator is rejected with InvalidStateError — closing a bypass of the XML QName check. GHSA-jxjr-3g7g-3944
• Security: the requireWellFormed serializer's DocType publicId/systemId validators no longer treat an interior line terminator as satisfying the anchor, so an identifier containing an ECMAScript line terminator is rejected with InvalidStateError — closing a bypass of the XML PubidLiteral/SystemLiteral check. GHSA-vr34-hp96-76pp
• Security: createElementNS(), createAttributeNS(), createDocumentType(), and createAttribute() now reject a name containing a line terminator with InvalidCharacterError, because name validation applies to the whole string — closing a creation-time bypass of the XML Name/QName production on the default serialization path. GHSA-3px3-54cx-rmw9
• Security: the parser now reports a not-well-formed end tag whose valid name is followed by trailing content (a recoverable error in XML, a warning in HTML) instead of accepting it silently, per the XML ETag production; parsing recovers to the byte-identical DOM. Consumers that want strict rejection can escalate the reported error to fatal via the parser's onError handler. GHSA-6h8r-xr42-gp59
• DOMExceptions raised during parsing are now reported as a fatalError, and the originating error is preserved as the cause on the resulting ParseError.

Thank you, @​ericchiang, @​KarimTantawey, @​bhaswanthc, @​arpitjain099, @​Paranoidgrinch, for your contributions

0.9.11

Commits

Fixed

• Security: XMLSerializer.serializeToString() now also rejects invalid element and attribute names when { requireWellFormed: true } is passed, throwing InvalidStateError for a name that is not a valid XML QName (this covers the namespace prefix, which surfaces in the element qualified name or in a synthesized xmlns: declaration). This prevents XML injection via createElement() / setAttribute(), extending the existing requireWellFormed checks to the serialized name set. GHSA-w2rr-34g9-rvrj GHSA-4w3w-2rp5-g8jm
• Security: the processing-instruction grammar regex no longer backtracks quadratically on an unterminated processing instruction (<?… with no closing ?>), preventing a denial-of-service (ReDoS) reachable from DOMParser.parseFromString with default options. GHSA-g53g-w8rj-fmg7
• CharacterData nodeValue and data are now kept in sync [#990](https://github.com/xmldom/xmldom/issues/990)

• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — preventing PI-target injection via >, ?, or whitespace. GHSA-c7q8-3ch8-vqpv
• Security: Document.createEntityReference() now rejects an invalid XML Name at creation, and XMLSerializer.serializeToString() under { requireWellFormed: true } validates an EntityReference nodeName as an XML Name, throwing InvalidStateError — preventing XML injection via an entity-reference name. GHSA-6gmq-8vp8-gcm6
• Security: the requireWellFormed serializer's element- and attribute-name validators no longer treat an interior line terminator as satisfying the name anchors, so a name containing a line terminator is rejected with InvalidStateError — closing a bypass of the XML QName check. GHSA-jxjr-3g7g-3944
• Security: the requireWellFormed serializer's DocType publicId/systemId validators no longer treat an interior line terminator as satisfying the anchor, so an identifier containing an ECMAScript line terminator is rejected with InvalidStateError — closing a bypass of the XML PubidLiteral/SystemLiteral check. GHSA-vr34-hp96-76pp
• Security: createElementNS(), createAttributeNS(), createDocumentType(), and createAttribute() now reject a name containing a line terminator with InvalidCharacterError, because name validation applies to the whole string — closing a creation-time bypass of the XML Name/QName production on the default serialization path. GHSA-3px3-54cx-rmw9
• Security: the parser now reports a not-well-formed end tag whose valid name is followed by trailing content (a recoverable error in XML, a warning in HTML) instead of accepting it silently, per the XML ETag production; parsing recovers to the byte-identical DOM. Consumers that want strict rejection can escalate the reported error to fatal via the parser's onError handler. GHSA-6h8r-xr42-gp59
• DOMExceptions raised during parsing are now reported as a fatalError, and the originating error is preserved as the cause on the resulting ParseError.

0.8.15

Fixed

• Security: parsing a deeply or repeatedly namespaced document no longer consumes quadratic memory; the in-scope namespace map is inherited through the prototype chain instead of being copied for every prefix-declaring element (O(N) instead of O(N²)), preventing a denial-of-service reachable from DOMParser.parseFromString with default options. Serialized output is byte-identical. GHSA-965w-775f-mr7g
• Security: attribute de-duplication during parsing is now O(M) instead of O(M²); the NamedNodeMap parse-time dedup path uses a null-prototype membership index, so a well-formed document with a hostile number of duplicate attributes can no longer wedge the parse. Attribute order and duplicate resolution (last value wins, first position kept) are byte-identical, preserving the XML no-duplicate-attributes well-formedness constraint. GHSA-8344-3jmq-59r6
• Security: trimming trailing whitespace from an XML end tag (ETag) is now anchored so it runs in linear time instead of backtracking quadratically on a long whitespace run, preventing a ReDoS reachable from DOMParser.parseFromString. Trimmed output is byte-identical. GHSA-x4fp-j954-r2f4
• Security: malformed-input recovery is now linear instead of quadratic — the malformed tag-name scan terminates at an embedded <, and Node.prototype.normalize() merges adjacent text nodes in O(K) instead of O(K²) (also reachable programmatically), per normalize() in the WHATWG DOM spec. DOM output is unchanged; only the reported error text differs. GHSA-93r5-fhx6-vmg9
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now rejects a DocType name that is not a valid XML Name, throwing InvalidStateError — matching the sibling publicId/systemId/internalSubset checks and preventing XML injection via DocumentType.name. GHSA-27p8-2357-5qqv
• Security: XMLSerializer.serializeToString() under { requireWellFormed: true } now validates a processing-instruction target as an XML NCName and rejects a case-insensitive xml, throwing InvalidStateError — a check 0.8.x did not previously perform, preventing PI-target injec...
