CVE-2025-2105Network attack vector

Object injection via untrusted PHAR deserialization

Published Apr 26, 2025 · Updated Apr 8, 2026

PHP object injection in Artbees Jupiter X Core 4.8.11 and earlier allows attackers to inject objects through crafted PHAR files. The raven_download_file function deserializes the untrusted file parameter, allowing PHAR metadata to instantiate attacker-controlled PHP objects. Exploitation requires a compatible POP chain in another installed plugin or theme; unauthenticated access also requires a file-download form and file upload, while Contributor access can create the form.
