Résumé
OpenClaw < 2026.2.19 - ReDoS and Regex Injection via Unescaped Feishu Mention Metadata
Description d'origine
La description telle que publiée par la source (souvent en anglais).
OpenClaw versions prior to 2026.2.19 construct RegExp objects directly from unescaped Feishu mention metadata in the stripBotMention function, allowing regex injection and denial of service. Attackers can craft nested-quantifier patterns or metacharacters in mention metadata to trigger catastrophic backtracking, block message processing, or remove unintended content before model processing.
