Detailsinfo

A vulnerability classified as critical was found in OpenClaw up to 2026.3.21. Affected by this vulnerability is some unknown processing of the component Setting Handler. The manipulation with an unknown input leads to a permissive list of allowed inputs vulnerability. The CWE definition for the vulnerability is CWE-183. The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are explicitly allowed by policy because the inputs are assumed to be safe, but the list is too permissive - that is, it allows an input that is unsafe, leading to resultant weaknesses. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

OpenClaw before 2026.3.22 contains a settings reconciliation vulnerability that allows attackers to bypass intended deny-all revocations by exploiting empty allowlist handling. The vulnerability treats explicit empty allowlists as unset during reconciliation, silently undoing intended access control denials and restoring previously revoked permissions.
