Lifecycle Timeline
3DescriptionCVE.org
OpenClaw before 2026.5.18 contain an authorization bypass vulnerability in exec allowlist glob matching that allows lower-trust callers to execute actions beyond intended authorization. Attackers can craft input paths that traverse the allowlist glob patterns to execute or persist unauthorized actions when the affected feature is enabled.
AnalysisAI
Authorization bypass in OpenClaw before 2026.5.18 lets a low-trust, authenticated caller escape the exec allowlist by abusing weak glob matching, executing or persisting actions beyond their intended authorization. Reported by VulnCheck and tracked as a path-traversal-class flaw (CWE-22), it carries a CVSS 4.0 score of 7.7 with high confidentiality, integrity, and availability impact but requires the affected exec feature to be enabled. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the OpenClaw exec allowlist / action-execution feature to be enabled (the AT:P attack requirement and the description's 'when the affected feature is enabled'), plus authenticated access as a lower-trust caller (PR:L) capable of supplying input paths to the exec interface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are moderate-to-serious but not emergency-tier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker holding a low-trust, authenticated OpenClaw account on a system where the exec feature is enabled crafts an input path designed to traverse the allowlist glob patterns. The malformed path matches (or slips past) the intended allowlist, causing OpenClaw to execute or persist an action the caller was never authorized to run, escalating their effective privileges within the application. … |
| Remediation | Vendor-released patch: 2026.5.18 - upgrade OpenClaw to 2026.5.18 or later, which corrects the exec allowlist glob-matching logic; this is the primary and recommended fix per the GitHub advisory (https://github.com/openclaw/openclaw/security/advisories/GHSA-34mr-7r3m-gfg7) and VulnCheck advisory (https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-glob-matching). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all OpenClaw deployments running versions before 2026.5.18 and identify which have the exec feature enabled; if operationally dispensable, disable exec immediately to eliminate the attack surface. …
