CVE-2026-22178
EPSS 0.07%OpenClaw has ReDoS and regex injection via unescaped Feishu mention metadata in RegExp construction
描述
## 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. ## Fix Commit(s) - `7e67ab75cc2f0e93569d12fecd1411c2961fcc8c` - `74268489137510b6f6349919d1e197b17290d92c` Thanks @allsmog for reporting.
