| Package | Affected versions | Patched versions |
|---|---|---|
| backdrop/backdrop | < 1.24.2 | 1.24.2 |
| backdrop cms | < 1.24.2 | 1.24.2 |
A stored Cross-site scripting (XSS) issue in Text Editors and Formats in Backdrop CMS before 1.24.2 allows remote attackers to inject arbitrary web script or HTML via the name parameter. When a user is editing any content type (e.g., page, post, or card) as an admin, the stored XSS payload is executed upon selecting a malicious text formatting option.
NOTE: the vendor disputes the security relevance of this finding because "any administrator that can configure a text format could easily allow Full HTML anywhere."
