Stored script execution via unneutralized tag value
Published Sep 29, 2023 · Updated Sep 23, 2024
Stored cross-site scripting in BeeCMS 4.0 allows remote authenticated users to execute script in an administrator's browser via a tag value. The save_content action stores the tag parameter without neutralizing HTML, and the content_list action later renders and executes the supplied script. An administrative session is required to submit the value, and a subsequent visit to the tag list triggers the stored payload.
