CVE-2026-53860 is a low-severity vulnerability rated 2.3/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
