4DescriptionCVE.org
A flaw has been found in poco-ai poco-claw up to 0.5.4. Affected is the function get_workspace_file of the file executor_manager/app/api/v1/workspace.py of the component Workspace API. Executing a manipulation of the argument user_id can lead to authorization bypass. The attack may be launched remotely. The exploit has been published and may be used. This patch is called 67fcc88505c57f77d3fcf04eb5b89425b10cbf48. Upgrading the affected component is recommended.
AnalysisAI
Unauthenticated authorization bypass in poco-ai/poco-claw's Workspace API allows remote attackers to access arbitrary users' workspace files by manipulating the user_id parameter in the get_workspace_file function. All versions through 0.5.4 are affected, with the executor manager's control-plane routes completely lacking token-based authentication before the fix. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The executor manager service must be network-reachable from the attacker - the API route was completely unauthenticated before the patch, so no credentials, session tokens, or special configuration are required. … 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:N/UI:N) indicates trivial, unauthenticated remote exploitation with no special attack requirements. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote attacker sends an unauthenticated HTTP GET request to the poco-claw executor manager's Workspace API endpoint (executor_manager/app/api/v1/workspace.py) with an arbitrary target victim's user_id value substituted in the request parameter. Because the API performs no token-based authentication and no ownership validation on the user_id, the server returns the workspace file belonging to the specified user. … |
| Remediation | Upgrade poco-claw to the version containing commit 67fcc88505c57f77d3fcf04eb5b89425b10cbf48, available via GitHub PR #135 (https://github.com/poco-ai/poco-claw/pull/135). … Detailed patch versions, workarounds, and compensating controls in full report. |
