Arbitrary file deletion via deserialization gadget chain
Published Mar 31, 2025 · Updated Apr 3, 2025
PHP object injection in Drupal AI (Artificial Intelligence) before 1.0.5 allows attackers to delete files via optional AI Automator Types. These types supply a gadget chain that acts on files when PHP unserializes attacker-controlled data, although Drupal does not identify the involved classes or methods. Exploitation requires the optional AI Automators submodule and a separate flaw that passes unsafe input to unserialize; the issue is not directly exploitable, while a viable chain can reach code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.0.0 <1.0.5
