Vulnerability from fkie_nvd - Published: 2026-10-11 13:17 - Updated: 2026-10-11 13:17
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Vearch 3.5.2 through 3.5.9 contains an incorrect authorization vulnerability in Role.HasPermissionForResources that ignores stored ReadOnly or None privilege levels for resources listed in a role. Authenticated non-root users can upsert and delete documents with read-only access, or call PUT /roles to grant their role WriteRead privileges, escalating toward cluster administrator access.
