Low priority for now. Upgrade to OpenClaw OpenClaw 2026.3.25 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
OpenClaw before 2026.3.25 contains an authentication bypass vulnerability in raw card send surface that allows unpaired recipients to mint legacy callback payloads. Attackers can send raw card commands to bypass DM pairing restrictions and reach callback handling without proper authorization.
