GHSA-X4FP-J954-R2F4 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...
Colord: Slow rejection of oversized malformed color strings
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...

GHSA-G53G-W8RJ-FMG7 xmldom PI grammar regex ReDoS: quadratic backtracking on unterminated processing instructions
Summary @xmldom/xmldom's processing-instruction PI grammar regex exhibits quadratic-time backtracking ReDoS when parsing an unterminated processing instruction. A single small XML document containing forces the regular expression engine into On² work, stalling the Node.js event loop. The input is...

NLTK: ReDoS in nltk.tgrep via unvalidated user-supplied regular expressions
Summary The NLTK tgrep module accepts user-supplied regular expressions and passes them to the Python re engine without a timeout or validation, enabling catastrophic backtracking ReDoS. Applications that expose the tgrep API to external input are vulnerable to a single-request denial of service...

CVE-2026-86081: Inefficient Regular Expression Complexity
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node clone operation matched an attacker-controlled destination path against the default N8NBLOCKFILEPATTERNS regular expression. The pattern ^./.git/.$ allowed catastrophic backtracking and ran...
PT-2026-88512
Impact The Git node's clone operation matched the destination path against the default N8N BLOCK FILE PATTERNS expression, which was written so that a crafted path caused catastrophic backtracking. Evaluation runs synchronously in the main n8n process, so an authenticated user could freeze the...
