AnalysisAI
Insecure Direct Object Reference (IDOR) in Apache Allura before 1.19.1 allows unauthorized access to multiple Artifact types due to missing server-side permission checks. Attackers who can interact with the platform can reference artifact objects directly by their identifiers and retrieve content beyond their authorization level, resulting in information disclosure across potentially broad artifact categories. …

Vulnerability AssessmentAI
| Exploitation | The IDOR is exploitable by any user who can send HTTP requests to the Allura application's artifact endpoints. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | No CVSS vector was provided by the reporter, so all metric assessments are inferred from the vulnerability description and CWE class. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user on an Allura instance hosting private projects directly manipulates artifact identifiers in HTTP requests - incrementing ticket IDs, substituting attachment slugs, or iterating over known artifact URL patterns - to retrieve artifacts belonging to projects or permission levels they are not authorized to access. Because the server omits the permission check, it returns the artifact content without verifying project membership or access control list entries. … |
| Remediation | Vendor-released patch: Apache Allura 1.19.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
