Summary
The affected software is the Advanced Custom Fields: Extended WordPress plugin and its PRO edition, which let site visitors submit front-end forms. The flaw allows anyone without a login to trigger execution of arbitrary WordPress shortcodes on the server when they submit a vulnerable form, potentially exposing site data or enabling unintended server-side actions.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
The Advanced Custom Fields: Extended and Advanced Custom Fields: Extended PRO WordPress plugins from 0.9.2.4 to 0.9.2.7 do not consistently disable shortcode processing in the confirmation message of their front-end forms, allowing unauthenticated visitors to have arbitrary shortcodes executed server-side when they submit a form whose stored configuration does not carry the relevant setting.
