Advancedcustomfields

Advanced Custom Fields is a widely used WordPress plugin ecosystem centered around its flagship Advanced Custom Fields and ACF Frontend Display products, which serve as foundational tools for extending WordPress content management and form functionality. The vendor's vulnerability profile centers on web-application input-handling and access-control weaknesses—including cross-site scripting, missing authorization checks, unrestricted file uploads, and unsafe deserialization—which are characteristic of plugins that bridge user-facing interfaces with backend data structures and file storage. A meaningful share of the vendor's disclosed vulnerabilities reach serious severity outcomes, and the exposure frequently acquires public exploit availability due to the transparent nature of WordPress plugin development and the broad attack surface presented by internet-facing sites. Current exploitation activity, severity distribution, and exposure breadth are shown alongside this summary.
