5DescriptionCVE.org
OpenClaw versions prior to 2026.2.23 contain an authorization bypass vulnerability in the ACP client that auto-approves tool calls based on untrusted toolCall.kind metadata and permissive name heuristics. Attackers can bypass interactive approval prompts for read-class operations by spoofing tool metadata or using non-core read-like names to reach auto-approve paths.
AnalysisAI
OpenClaw versions prior to 2026.2.23 contain an authorization bypass vulnerability in the ACP (Approval Control Panel) client that automatically approves tool calls based on untrusted metadata and overly permissive heuristics. An authenticated attacker with PR (privileges required) can bypass interactive approval prompts for read-class operations by spoofing toolCall.kind metadata or using non-core read-like function names to reach auto-approve execution paths. …

Vulnerability AssessmentAI
| Risk Assessment | The CVSS 3.1 score of 5.4 (Medium) reflects moderate real-world risk with favorable attack conditions: the vulnerability requires low attack complexity (AC:L), network accessibility (AV:N), but mandates user privileges (PR:L), limiting opportunistic exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged authenticated user with access to OpenClaw's ACP client crafts a malicious tool invocation with a spoofed toolCall.kind metadata field (e.g., setting kind to a value matching permissive read-heuristics) or uses a function name like read_sensitive_data that matches non-core naming patterns. Due to insufficient metadata validation, the ACP client automatically approves the operation and executes it without presenting an interactive approval prompt, allowing the attacker to read confidential data or modify system state without authorization. … |
| Remediation | Upgrade OpenClaw to version 2026.2.23 or later immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
