Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privileged account on the target GoClaw instance (PR:L per CVSS vector) - unauthenticated exploitation is not supported by available data. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 2.1 is very low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who holds a low-privileged account on a GoClaw deployment sends a crafted HTTP request targeting the `auth`-gated evolution endpoints, exploiting the improper authorization logic to perform actions beyond their assigned permission level - such as triggering unintended state changes or degrading service availability. A public proof-of-concept is available via GitHub issue #1120, lowering the bar for exploitation by less sophisticated actors. …
Remediation No vendor-released patched version has been identified in the available data at time of analysis - the project tagged the issue as a bug via GitHub issue #1120 (https://github.com/nextlevelbuilder/goclaw/issues/1120), but no corresponding fix commit or tagged release version was provided in the references. … Detailed patch versions, workarounds, and compensating controls in full report.
