The WordPress Infinite Scroll – Ajax Load More plugin for WordPress is vulnerable to deserialization of untrusted input via the ‘alm_repeaters_export’ parameter in versions up to, and including 5.5.3.

It also requires that the attacker is successful in uploading a file with the serialized payload.
