Technical details
The vulnerability exists due to insufficient input sanitization and output escaping of the 'id' parameter in the Contest Gallery WordPress plugin. This security flaw has been assigned a CVSS v3.1 Base Score of 6.4 MEDIUM (Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). The vulnerability affects authenticated users with Contributor-level access and above (NVD, Wiz).
Impact

This could lead to theft of sensitive information, session hijacking, or other client-side attacks against site visitors (Wiz).
Mitigation and workarounds
The vulnerability has been patched in version 26.0.7 of the Contest Gallery plugin. Site administrators should update to this version immediately. The fix includes improved input sanitization and output escaping for the 'id' parameter (Wiz).
