FKIE_CVE-2026-1253

Vulnerability from fkie_nvd - Published: 2026-03-21 04:16 - Updated: 2026-06-17 10:15
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
Summary
The Group Chat & Video Chat by AtomChat plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'atomchat_update_auth_ajax' and 'atomchat_update_layout_ajax' functions in all versions up to, and including, 1.1.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update plugin options, including critical settings such as API keys, authentication keys, and layout configurations.
