CVE-2026-93990: Improper Handling of Unicode Encoding

Expat before 2.8.5 fails to validate that a high surrogate in UTF-16 input is followed by a low surrogate, allowing malformed UTF-16 sequences to be accepted. Attackers can supply UTF-16 encoded XML containing lone high surrogates that consume the following code unit, causing Expat to pass unpair...

GHSA-JXJR-3G7G-3944 xmldom: requireWellFormed element/attribute name validation is bypassable via an embedded line terminator

Summary An embedded line terminator bypasses the requireWellFormed serializer check for element and attribute names. The check was added to fix GHSA-w2rr-34g9-rvrj and GHSA-4w3w-2rp5-g8jm; a name whose first line is well-formed slips past it and is serialized verbatim, so the characters after the...
