CVE-2023-5803Network attack vector

Unauthorized actions via missing nonce validation

Published Nov 30, 2023 · Updated Apr 28, 2026

Cross-site request forgery in Business Directory Plugin 6.3.10 and earlier allows remote attackers to perform an unauthorized action. The affected request handler omits or incorrectly performs WordPress nonce validation, but public records do not identify the function or action. Exploitation requires an administrator authenticated to the site to visit a crafted page or link, and the CNA bounds the published impact to an unwanted state change.
