CVE-2022-2444Network attack vector

Authenticated arbitrary object invocation via PHAR deserialization

Published Jul 18, 2022 · Updated Apr 8, 2026

Deserialization of untrusted data in Visualizer 3.7.9 and earlier allows remote authenticated users to invoke arbitrary PHP objects. The remote_data parameter accepts a PHAR URI without scheme validation, causing PHP file handling to deserialize attacker-controlled archive metadata. Contributor privileges, a successfully uploaded serialized file, and a usable POP chain are required; the resulting object invocation can execute chain-defined actions.
