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.
