Extension Site Crawler
Monthly
Remote code execution in the TYPO3 Crawler extension occurs when the X-T3Crawler-Meta response header from a crawled URL is passed unchecked to PHP's unserialize(), enabling arbitrary PHP object injection. Exploitation requires a high-privileged administrator to configure a crawler-enabled page and a Scheduler task pointing at an attacker-controlled endpoint, so while impact is full RCE on the TYPO3 host, it is gated by an unusual combination of admin access, user interaction, and externally reachable malicious URLs. No public exploit identified at time of analysis and no CISA KEV listing.
