OpenClaw < 2026.4.14 - Authorization Context Reuse in Collect-Mode Queue Batches

Title source: cna
STIX 2.1

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.
