Arbitrary file deletion via caller-controlled decryption secret
Published May 14, 2025 · Updated Apr 8, 2026
PHP object injection in Uncanny Owl Uncanny Automator 6.4.0.1 and earlier allows remote attackers to delete arbitrary files. Several AJAX handlers pass attacker-controlled message and nonce values to automator_api_decode_message(), which decrypts and then calls maybe_unserialize() on the plaintext. No authentication or user interaction is required; exploitation also requires a usable POP chain, and the bundled chain can delete a chosen server file.

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.
