CVE-2026-87819: Inefficient Regular Expression Complexity

GitPython before 3.1.60 contains a regular expression denial of service vulnerability in Actor.nameemailregex that processes commit author and committer fields. Attackers can craft a commit object with a malformed author field containing an unterminated angle bracket to cause quadratic...

CVE-2026-86083

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the legacy expression engine generated source text by calling the mutable global JSON.stringify while printing synthetic string literals and interpolating timezone data. An expression could replace...

xmldom: End-tag Whitespace-Trim Regex ReDoS — quadratic backtracking in the 0.8.x end-tag parser

Summary On the @xmldom/xmldom 0.8.x line, parsing an XML end tag whose name is followed by a long run of whitespace and then a non-whitespace character triggers quadratic-time regular-expression backtracking ReDoS, so a single small crafted end tag stalls the Node.js event loop. It is reachable...

Impact colord's CSS color string matchers described a number as +-?\d.?\d+. In that form \d and \d+ can match the same digits, so a run of n digits can be divided between them in On² ways, and rejecting an input retries every division. Parsing is synchronous and uninterruptible, so a long...
