CVE-2021-36878Network attack vector

Settings modification via forged cross-site requests

Published Sep 27, 2021 · Updated Apr 28, 2026

Cross-site request forgery in StylemixThemes uListing 2.0.5 and earlier allows remote attackers to update plugin settings. The public advisory does not identify a specific request handler; the 2.0.6 changelog states that CSRF requests were fixed in all plugin sections. Exploitation requires an authenticated administrator to submit an attacker-controlled request, and the documented consequence is limited to settings modification.
