Attackers can exploit differing normalization logic to discard non-portable keys during approval processing while accepting them at execution time, bypassing operator review and potentially influencing runtime behavior including execution of attacker-controlled binaries.\n\n## Affected\n\n- `OpenClaw < b57b680c0c34de907d57f60c38fb358e82aef8f7`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":41.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
