"summary": "TYPO3 extension \"ceselector\" affected by Insecure Deserialization",
"details": "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.",
