CVE-2026-86083 n8n: Expression Sandbox Escape via Shared Builtin Tampering and Code-Printer Injection Leads to Code Execution
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...
CVE-2026-86083
n8n , an open-source workflow automation platform, is affected by a sandbox escape in its legacy expression engine. The root cause is that the engine called the mutable global JSON.stringify while generating source text for synthetic string literals and timezone interpolation. A crafted expressio...
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...
GHSA-2WM5-Q62R-HMRV 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...

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...
