CVE-2026-46725 · Remote Code Execution in extension "Content Element Selector" (ceselector)
This page contains facts from public vulnerability sources. Check the original advisory before updating.
The extension passes an attacker-controlled cookie directly to PHP's unserialize() without safely processing the input. A remote, unauthenticated attacker can supply a crafted serialized payload to trigger PHP Object Injection, leading to Remote Code Execution on the TYPO3 server. Exploitation requires the content element to be configured with "Persistent Mode: Static" in the plugin settings.
