DescriptionCVE.org

OpenClaw before 2026.5.18 contains a command injection vulnerability where shell wrapper argv could change between approval and execution. Attackers can rebuild command arguments after allowlist approval to execute unapproved command shapes, potentially bypassing security controls.

AnalysisAI

Command injection in OpenClaw before 2026.5.18 allows authenticated attackers to modify shell wrapper argv between approval and execution, bypassing the allowlist enforcement. The TOCTOU-style race against the approval gate lets attackers execute unapproved command shapes with the application's privileges, with no public exploit identified at time of analysis but a vendor advisory published via GHSA.

Vulnerability AssessmentAI

Exploitation Exploitation requires authenticated access to OpenClaw's shell wrapper command-submission interface (PR:L) and the ability to influence argv between the allowlist approval step and the execution step - the prerequisite is therefore a deployment that exposes the wrapper to users who can supply commands and a target where the argv source is mutable across the approval/execution boundary. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) with VC:H/VI:H/VA:H and a base score of 8.7 indicates a network-reachable, low-complexity flaw requiring only low privileges and yielding full confidentiality, integrity, and availability impact on the vulnerable system - a credible high-priority issue for any deployment exposing the wrapper to authenticated users. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with low-privileged authenticated access submits a command through OpenClaw's shell wrapper that presents an allowlisted argv at approval time, then mutates the underlying argument source so that execution receives a different, unapproved command shape - for example swapping a benign flag for a shell-redirect or invoking an off-allowlist binary. No public exploit code has been identified, but the race window is intrinsic to the wrapper's design and reproducible once the approval/execution split is understood.
Remediation Vendor-released patch: upgrade OpenClaw to 2026.5.18 or later per the GHSA-2j8v-hwgc-x698 advisory (https://github.com/openclaw/openclaw/security/advisories/GHSA-2j8v-hwgc-x698). … Detailed patch versions, workarounds, and compensating controls in full report.
