PHP object injection via nonce-less path validation
Published Feb 9, 2023 · Updated Apr 8, 2026
PHP object injection in Rickard Westerlind ImageMagick Engine 1.7.5 and earlier allows remote attackers to invoke PHAR deserialization. The nonce-less ime_ajax_test_im_path action passes attacker-selected cli_path data through realpath and executable checks, causing PHP to process PHAR metadata. Exploitation requires an authenticated administrator to follow a crafted link, an uploaded serialized payload, and an available POP chain; successful object execution grants the chain's PHP-level effects.

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.
