Lifecycle Timeline
2DescriptionCVE.org
OpenClaw versions before 2026.5.18 contain an authorization bypass vulnerability in skill command dispatch that allows lower-trust callers to execute or persist actions beyond their intended authorization. Attackers can bypass tool policy restrictions through configured input paths to perform unauthorized actions when the affected feature is enabled and reachable.
AnalysisAI
Authorization bypass in OpenClaw before version 2026.5.18 allows authenticated low-privilege callers to exceed their intended permissions within the skill command dispatch subsystem. Exploiting misconfigured or reachable input paths, an attacker can circumvent tool policy restrictions and execute or persist actions at a higher trust level than authorized when the affected feature is active and reachable. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated access at a low-privilege trust level (PR:L per the CVSS 4.0 vector) - unauthenticated access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.3 (AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N) signals limited real-world risk despite the network-accessible vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated low-privilege user with network access to an OpenClaw deployment where the skill command dispatch feature is enabled and input paths are configured in an exposed state sends a crafted dispatch request targeting an unauthorized skill action. The authorization check fails to correctly validate the caller's trust level (CWE-863), and the action is executed or persisted as if the caller held elevated permissions. … |
| Remediation | Upgrade OpenClaw to version 2026.5.18 or later, which resolves the authorization bypass in the skill command dispatch subsystem per the vendor advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-mhm4-93fw-4qr2. … Detailed patch versions, workarounds, and compensating controls in full report. |
