Unauthenticated PHP Object Injection in ThemeREX Addons < 2.45.0 versions.
AnalysisAI
Unauthenticated PHP Object Injection in the ThemeREX Addons (trx_addons) WordPress plugin before 2.45.0 lets remote attackers inject arbitrary serialized PHP objects into the application. Because no authentication is required (CVSS 9.8, PR:N/UI:N), an attacker can supply crafted serialized data to a vulnerable entry point; when combined with a suitable POP gadget chain present in the plugin, another plugin, a theme, or WordPress core, this can escalate to code execution, arbitrary file operations, or data compromise. …
