The software fails to pin the executable identity when the argv[0] token does not look like a file path, so a post\u2011approval rebind can subvert the operator\u2019s approval. This flaw enables an attacker to run arbitrary commands with the privileges of the operator, resulting in Remote Code Execution. The weakness is identified as CWE\u2011367, indicating improper verification of executable identity.", "risk_and_exploitability": "The CVSS base score is 4.4, indicating a moderate severity risk. EPSS data is not provided and the issue is not in the CISA KEV catalog, suggesting no known active exploitation in the wild. However, the attack requires that the attacker be able to modify the PATH after an approval has been granted, typically implying local or privileged conditions. If successful, the attacker gains full control over the system and can compromise confidentiality, integrity, and availability. No public exploits are reported, but the potential for future exploitation warrants prompt action."}}}}, "created": "2026-03-19T08:54:49.177723+00:00", "updated": "2026-03-25T11:55:34.488192+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
