Summary

10up Distributor before 2.3.2 contains a PHP object injection flaw (CWE-502) in the set_meta() function in includes/utils.php. The function unserializes post meta a second time, so a user with Contributor-level access can make the site instantiate attacker-defined PHP objects. The impact depends on which gadget classes are loaded on the destination site.

Description from the CNA

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.
