Name of the Vulnerable Software and Affected Versions pixxio extension for TYPO3 versions prior to 1.0.6

Description An issue in the pixxio extension for TYPO3 allows an attacker to exploit a Server-Side Request Forgery (SSRF) vulnerability. This occurs because the extension fails to restrict image downloads to the configured pixx.io DAM URL. As a result, an attacker can download content from a remote location and save it to a user-controlled filename, potentially leading to Remote Code Execution. Exploitation requires a TYPO3 backend user account.

Recommendations For versions prior to 1.0.6, update to version 1.0.6 or later to resolve the issue.
