CVE-2026-53863
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOpenClaw before 2026.4.25 contains an input validation vulnerability in tool group policy callers that accept unvalidated group IDs. Attackers who can supply a group ID to the policy resolver could trigger incorrect group-policy decisions for tool invocations, potentially bypassing intended access controls.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpenClaw before version 2026.4.25 fails to validate group IDs passed to tool group policy callers. The policy resolver accepts unvalidated group IDs supplied by users, allowing attackers to manipulate group-policy decisions for tool invocations and potentially bypass access controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed OpenClaw versionRun the version command or check the application metadata (e.g., openclaw --version, or inspect the software manifest/binary properties)Affected if The version is 2026.4.25 or any version prior to 2026.4.25
-
Identify if the policy resolver component is present and activeLocate and inspect the policy resolver module in the OpenClaw installation directory or confirm its loaded status in the running applicationAffected if The policy resolver is present and handles group policy decisions for tool invocations
-
Verify whether tool group policy functionality is enabledExamine the OpenClaw configuration files or settings for tool group policy features, or check if any tools are configured to use group-based policiesAffected if Tool group policy features are enabled and the policy resolver processes group IDs from users
-
Inspect group ID validation in policy resolverReview the policy resolver source code or binary for group ID validation logic, focusing on entry points where user-supplied group IDs are acceptedAffected if The policy resolver lacks rigorous validation of group ID format or existence before using them in policy decisions
A user is affected if OpenClaw version is 2026.4.25 or earlier AND the policy resolver with tool group policy functionality is actively processing user-supplied group IDs without proper validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2026.4.25
Implement rigorous validation of all group IDs at the policy resolver entry point before using them in any policy decisions. Reject or sanitize any group ID that does not conform to expected format or that references non-existent groups.
2026.4.25
- Upgrade OpenClaw to version 2026.4.25 or later to resolve the IDOR vulnerability in tool group policy callers
