Title

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

Summary

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.

Severity

Summary

OpenClaw: Collect-mode queue batches could reuse the last sender authorization context

Details

Summary

Collect-mode queue batches could reuse the last sender authorization context.

Affected Packages / Versions

Package: openclaw
Ecosystem: npm
Affected versions: < 2026.4.14
Patched versions: >= 2026.4.14

Impact

Collect-mode queued messages from different senders could be drained as one batch using the final sender's authorization context, allowing earlier messages to inherit a more privileged context.

Technical Details

The fix splits collect-mode batches by sender authorization context before dispatch, preserving each message's own trust state.

Fix

The issue was fixed in #66024. The first stable tag containing the fix is v2026.4.14, and openclaw@2026.4.14 includes the fix.

Fix Commit(s)

43d4be902755c970b3d15608679761877718da69
PR: #66024

Release Process Note

Users should upgrade to openclaw 2026.4.14 or newer. The latest npm release, 2026.4.14, already includes the fix.

Vulnerability from github – Published: 2026-04-17 21:35 – Updated: 2026-05-08 01:32

Summary

OpenClaw: Collect-mode queue batches could reuse the last sender authorization context

Details

Summary

Collect-mode queue batches could reuse the last sender authorization context.

Affected Packages / Versions

Package: openclaw
Ecosystem: npm
Affected versions: < 2026.4.14
Patched versions: >= 2026.4.14

Impact

Collect-mode queued messages from different senders could be drained as one batch using the final sender's authorization context, allowing earlier messages to inherit a more privileged context.

Technical Details

The fix splits collect-mode batches by sender authorization context before dispatch, preserving each message's own trust state.

Fix

The issue was fixed in #66024. The first stable tag containing the fix is v2026.4.14, and openclaw@2026.4.14 includes the fix.

Fix Commit(s)

PR: #66024

Release Process Note

Users should upgrade to openclaw 2026.4.14 or newer. The latest npm release, 2026.4.14, already includes the fix.
