Bump @xmldom/xmldom from 0.8.13 to 0.8.15 - #777

Sourced from @​xmldom/xmldom's releases.

0.8.15

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: 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 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 parser now reports a not-well-formed end tag whose valid name is followed by trailing content as a recoverable error 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 errorHandler. GHSA-6h8r-xr42-gp59

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
