Summary
OpenClaw has ReDoS and regex injection via unescaped Feishu mention metadata in RegExp construction
Details

Summary

extensions/feishu/src/bot.ts constructed new RegExp() directly from Feishu mention metadata (mention.name, mention.key) in stripBotMention() without escaping regex metacharacters.

Affected Packages / Versions

  • Package: npm openclaw
  • Affected versions: <= 2026.2.17
  • First affected release: 2026.2.6
  • Patched version: 2026.2.19

Impact

  • ReDoS: crafted nested-quantifier patterns in mention metadata can trigger catastrophic backtracking and block message processing.
  • Regex injection: metacharacters in mention metadata can remove unintended message content before it is sent to the model.
