    Issue
    The TYPO3 "Content Element Selector" (ceselector) 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. This has been patched in version 3.0.3, 4.0.2, 5.0.1, and 6.0.1.

    Recommended action: Upgrade to 6.0.1, 5.0.1, 4.0.2 or 3.0.3 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
