DescriptionGitHub Advisory

Kiteworks is a private data network (PDN). Versions 9.2.0 and 9.2.1 of Kiteworks Core have an access control vulnerability that allows authenticated users to access unauthorized content. Upgrade Kiteworks Core to version 9.2.2 or later to receive a patch.

AnalysisAI

An access control vulnerability exists in Kiteworks Core versions 9.2.0 and 9.2.1 that allows authenticated users to access unauthorized content within the private data network. With a CVSS score of 8.8 (High), an attacker with low-level authenticated access can potentially access, modify, or delete sensitive data they should not have permissions to view. No public proof-of-concept or active exploitation (KEV listing) has been reported at this time.

Technical ContextAI

Kiteworks Core (cpe:2.3:a:kiteworks:core) is a private content network platform designed for secure file sharing and collaboration. This vulnerability is classified as CWE-282 (Improper Privilege Management), indicating a failure in the access control mechanism that enforces authorization boundaries between users and content. The flaw allows authenticated users to bypass intended access restrictions, potentially exposing sensitive documents, files, or data stored within the Kiteworks environment that should be protected by role-based or attribute-based access controls.

RemediationAI

Upgrade Kiteworks Core to version 9.2.2 or later immediately to remediate this vulnerability, as specified in the vendor security advisory at https://github.com/kiteworks/security-advisories/security/advisories/GHSA-5gqr-cpr6-wvm5. Organizations that cannot immediately upgrade should implement enhanced monitoring of user access patterns to detect potential unauthorized content access, review and restrict user privileges to minimum necessary levels, and consider implementing additional network segmentation to limit exposure until patching is complete. Audit logs should be reviewed for any suspicious access patterns that may indicate exploitation of this vulnerability in affected versions 9.2.0 and 9.2.1.
