CVE-2025-6991Network attack vector

Contributor-level code execution via unrestricted widget file inclusion

Published Jul 26, 2025 · Updated Apr 8, 2026

Local file inclusion in Hogash Studio Kallyas 4.21.0 and earlier allows remote authenticated users to execute uploaded PHP files. The TH_LatestPosts4 widget passes an attacker-selected local PHP path to an include operation without restricting the referenced file. Contributor-level access is required, and code execution depends on a PHP file being uploadable and then selected for inclusion; successful exploitation can also expose sensitive server data or bypass access controls.
