Description

OpenClaw before 2026.4.14 contains an authorization context reuse vulnerability in collect-mode queue batches that allows messages from different senders to inherit the final sender's authorization context. Attackers can exploit this by sending multiple queued messages to drain batches using a more privileged sender's context, causing earlier messages to execute with elevated permissions.

Affected products

• OpenClaw: before 2026.4.14 — fixed in 2026.4.14

How to fix

Upgrade to a fixed version: OpenClaw 2026.4.14. Check the vendor advisory for mitigations.
