**Name of the Vulnerable Software and Affected Versions** Backdrop CMS versions 1.13.x through 1.13.4 Backdrop CMS versions 1.14.x through 1.14.1 **Description** An issue allows the upload of entire-site configuration archives through the user interface or command line. It does not sufficiently check uploaded archives for invalid data, allowing non-configuration scripts to potentially be uploaded to the server. This issue is mitigated by the fact that the attacker would be required to have the "Synchronize, import, and export configuration" permission, a permission that only trusted administrators should be given. Other measures in the product prevent the execution of PHP scripts, so another server-side scripting language must be accessible on the server to execute code. **Recommendations** For Backdrop CMS versions 1.13.x through 1.13.4, update to version 1.13.5 or later. For Backdrop CMS versions 1.14.x through 1.14.1, update to version 1.14.2 or later.

**Name of the Vulnerable Software and Affected Versions** Joomla! versions prior to 3.9.12 **Description** The issue is related to inadequate escaping, which allowed XSS attacks. Specifically, the logo parameter of the default templates was vulnerable to such attacks. **Recommendations** For versions prior to 3.9.12, update to version 3.9.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the logo parameter in the default templates until a patch is applied.
