Overview

The Funnelforms Free plugin for WordPress (versions up to 3.4) contains a vulnerability identified as CVE-2023-5386. The vulnerability stems from a missing capability check on the fnsfdeleteposts function, which was discovered and disclosed in November 2023. This security flaw affects WordPress installations with the Funnelforms Free plugin installed (NVD).

Technical details

The vulnerability is classified as a Missing Authorization issue (CWE-862) with a CVSS v3.1 base score of 6.5 (Medium) according to Wordfence's assessment, while the NVD rates it at 4.3 (Medium). The technical root cause is the absence of proper capability checks in the fnsfdeleteposts function, which should restrict access to post deletion functionality (NVD).

The vulnerability allows authenticated attackers with subscriber-level permissions or higher to delete arbitrary posts, including administrator posts and content not related to the Funnelforms Free plugin. This represents a significant breach of content management security within WordPress installations (NVD).
