CVE-2026-18035: CWE-862 Missing Authorization in User Access Manager
The User Access Manager WordPress plugin before 2.3.15 does not apply its access restrictions to REST API requests, allowing unauthenticated attackers to read the content of posts, pages and custom post types that have been restricted to specific user groups.
AI Analysis
Technical Summary
CVE-2026-18035 is a missing authorization vulnerability (CWE-862) in the User Access Manager WordPress plugin prior to version 2.3.15. The plugin fails to apply its access control restrictions to REST API requests, enabling unauthenticated attackers to read restricted content that is intended only for certain user groups. This flaw compromises content confidentiality by bypassing intended access controls via the REST API.
Potential Impact
Unauthorized users can access restricted content through the REST API, potentially exposing sensitive or private posts, pages, and custom post types that are meant to be limited to specific user groups. This leads to a breach of content confidentiality but does not indicate privilege escalation or code execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor the vendor's official channels for updates and apply any released patches or updates to version 2.3.15 or later once available. Until then, consider restricting REST API access or disabling it if not required.
