CVE-2026-53860

LOW 2.3EPSS 0.17%

Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

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.
