CVE-2026-111628
What it is
10up Distributor before 2.3.2 contains a PHP object injection vulnerability that allows Contributor-level users to instantiate PHP objects by double unserializing distributed post meta. Attackers can store a serialized PHP string as meta, which set_meta() in includes/utils.php unserializes on the destination site, storing attacker-defined objects whose impact depends on loaded gadget classes.
