CVE-2026-2626Public exploitNetwork attack vector

Unauthenticated option modification via unsafe deserialization

Published Mar 11, 2026 · Updated Mar 11, 2026

PHP object injection in Dan Mossop Divi Booster before 5.0.2 allows remote attackers to alter plugin options through an unauthenticated upload. An unauthenticated fixing function accepts a gzip-compressed serialized upload, passes its decompressed contents to unserialize(), and stores the result in the wtfdivi option. Exploitation requires Divi to be active and its settings saved once; object injection additionally requires a usable PHP gadget chain, while option modification does not.
