Summary
OpenClaw before 2026.5.7 contains a sender policy bypass vulnerability in BlueBubbles that allows participants to match allowlist entries through conversation metadata rather than stable sender identity. Attackers can influence conversation-level identifiers to receive agent responses intended for configured senders, potentially bypassing access controls.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of openclaw/openclaw published their own advisory on GitHub. Reviewed sources take precedence over it.
