The vulnerability is not listed in the CISA KEV catalog, implying no publicly known active exploits. The likely attack vector requires an attacker to supply a malformed TAR archive to the OpenClaw extraction routine; if such archives can be provided remotely through an API or upload endpoint, the potential impact increases. If the archive originates locally, the risk is confined to the host system. The flaw compromises file integrity and can lead to arbitrary code execution when an attacker overwrites executable or privileged files."}}}}, "created": "2026-03-06T15:00:29.651696+00:00", "updated": "2026-04-17T12:45:16.137330+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
