CVE-2022-2437Network attack vector

Unauthenticated object injection via PHAR metadata deserialization

Published Jul 18, 2022 · Updated Apr 8, 2026

Deserialization in SlickRemix Feed Them Social 2.9.8.5 and earlier allows remote attackers to invoke PHP objects through fts_url. The fts_url handler accepts a PHAR-wrapper file path and triggers deserialization of metadata from the attacker-controlled archive. Exploitation requires an uploaded serialized payload and a usable POP chain; resulting actions depend on the PHP object gadgets present in the WordPress installation.
