CVE-2022-2433Network attack vector

Arbitrary PHP object invocation via PHAR paths

Published Sep 6, 2022 · Updated Apr 8, 2026

PHP object injection in Ajax Load More 5.5.3 and earlier allows remote attackers to invoke arbitrary PHP objects via a crafted request. The alm_repeaters_export handler passes an attacker-supplied path to file_exists and readfile, causing PHP to parse serialized metadata when the path uses the PHAR wrapper. Exploitation requires an uploaded serialized payload, a usable POP chain, and a site administrator to follow the crafted link; resulting actions depend on the available chain.
