RUSTSEC-2026-0193 mXSS in ammonia via MathML `annotation-xml` encoding strip

If a certain set of MathML tags are enabled, an attacker can inject arbitrary JavaScript code into the user's browser. The annotation-xml tag has slightly different behavior than the other "integration point" tags in MathML and SVG, but ammonia didn't handle it, so it didn't correctly strip the...

RUSTSEC-2026-0195 Unbounded namespace-declaration allocation in `NsReader` enables memory-exhaustion denial of service

NsReader resolves namespaces by calling NamespaceResolver::push for every Start/Empty event before the event is returned to the caller. push iterated all xmlns / xmlns: attributes on the start tag and, for each one, appended the prefix bytes to an internal buffer and pushed a NamespaceBinding 32...

RUSTSEC-2026-0194 Quadratic run time when checking a start tag for duplicate attribute names

BytesStart::attributes returns an Attributes iterator which, by default withcheckstrue, rejects a start tag that repeats an attribute name. For each attribute yielded, the iterator compared the new name against every name seen so far in the same tag using a linear scan, so a start tag with N...
