DescriptionCVE.org

OpenClaw 2026.2.12 before 2026.5.26 contain an authorization bypass vulnerability in the hooks allowedAgentIds validation. A lower-trust caller or configured input path can bypass agent ID restrictions by submitting blank agent IDs, allowing actions that should require stronger authorization or policy checks.

AnalysisAI

Authorization bypass in OpenClaw's hooks allowedAgentIds validation allows a lower-trust authenticated caller to circumvent agent ID restrictions by submitting blank agent IDs, effectively elevating privileges to perform actions gated behind stronger policy controls. Affected versions span OpenClaw 2026.2.12 through versions prior to 2026.5.26, with the flaw traceable to improper input validation of the agent identifier field during hook processing. …

Vulnerability AssessmentAI

Exploitation The attacker must hold low-privilege access to the OpenClaw instance (PR:L per CVSS 4.0 vector), ruling out fully unauthenticated exploitation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 6.0 reflects a moderate-severity finding with a meaningful integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated lower-trust caller with access to the OpenClaw hooks API submits a hook invocation request with a blank agent ID field in place of a valid, policy-approved identifier. The `allowedAgentIds` validation logic fails to reject the empty value, treating it as passing the allowlist check, and the hook executes with permissions intended only for explicitly authorized agents. …
Remediation The primary fix is to upgrade to OpenClaw 2026.5.26 or later, which resolves the blank agent ID bypass in the hooks `allowedAgentIds` validation. … Detailed patch versions, workarounds, and compensating controls in full report.
