Published May 30, 2022 · Updated Aug 2, 2024
Stored XSS in Khaled User Meta before 2.4.3 allows remote authenticated users to run scripts through crafted form names or field labels. The plugin stores Form Name and Shared Field Label values without sanitization and renders them in the form editor without output escaping. Administrator access is required to save a payload, which executes in the browser when an administrator edits the affected form or field.
