Extension Content Element Selector
Monthly
Remote code execution in the TYPO3 'Content Element Selector' extension allows unauthenticated attackers to execute arbitrary PHP code by sending a crafted cookie that the extension feeds directly into PHP's unserialize(). The flaw (CWE-502, CVSS 4.0 score 9.2) is exploitable only on installations where a content element is configured with 'Persistent Mode: Static'. No public exploit identified at time of analysis, though the deserialization pattern is well-understood and typically rapid to weaponize.
