Executive Summary

This vulnerability exists in OpenClaw versions before 2026.2.25 and involves the Nextcloud Talk webhook events. The issue is that OpenClaw lacks a durable replay state for these webhook events, which means that valid signed requests can be captured and replayed by attackers.

As a result, attackers can resend previously valid signed webhook requests, causing the system to process duplicate inbound events. This can lead to problems with data integrity or availability.

Impact Analysis

The vulnerability allows attackers to replay valid signed webhook requests, which can trigger duplicate processing of inbound events.

  • Integrity issues: Duplicate processing may cause inconsistent or corrupted data.
  • Availability issues: Replaying requests could overload the system or disrupt normal operations.
