MEDIUM6.3EPSS 0.08%OpenClaw's Nextcloud Talk webhook missing rate limiting on shared secret authentication
發布日:2026/3/31修改日:2026/4/6
描述
## Summary Nextcloud Talk webhook signature failures were not throttled even though the integration relies on an operator-configured shared secret that may be weak. ## Impact An attacker who could reach the webhook endpoint could brute-force weak secrets online and then forge inbound webhook events. ## Affected Component `extensions/nextcloud-talk/src/monitor.ts` ## Fixed Versions - Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix. ## Fix Fixed by commit `e403decb6e` (`nextcloud-talk: throttle repeated webhook auth failures`). OpenClaw thanks @AntAISecurityLab for reporting.
