CVE-2025-46595 (GCVE-0-2025-46595)
Vulnerability from cvelistv5 – Published: 2025-04-25 00:00 – Updated: 2025-04-25 14:28
VLAI?
Summary
An XSS issue was discovered in the Flag module before 1.x-3.6.2 for Backdrop CMS. Flag is a module that allows flags to be added to nodes, comments, users, and any other type of entity. It doesn't verify flag links before performing the flag action, or verify that the response returned was provided by the flag module. This can allow crafted HTML to result in Cross Site Scripting. This is mitigated by the fact that an attacker must have a role with permission to create links on the website, for example: create or edit comments or content with a filtered text format.
Severity ?
6.4 (Medium)

Summary
An issue was discovered in the Mail Disguise module before 1.x-1.0.5 for Backdrop CMS. It enables a website to obfuscate email addresses, and should prevent spambots from collecting them. The module doesn't sufficiently validate the data attribute value on links, potentially leading to a Cross Site Scripting (XSS) vulnerability. This is mitigated by the fact an attacker must be able to insert link (<a>) HTML elements containing data attributes into the page.

Summary
An issue was discovered in the Masquerade module before 1.x-1.0.1 for Backdrop CMS. It allows people to temporarily switch to another user account. The module provides a "Masquerade as admin" permission to restrict people (who can masquerade) from switching to an account with administrative privileges. This permission is not always honored and may allow non-administrative users to masquerade as an administrator. This vulnerability is mitigated by the fact that an attacker must have a role with the "Masquerade as user" permission.

CVE-2025-25062 (GCVE-0-2025-25062)

Summary
An XSS issue was discovered in Backdrop CMS 1.28.x before 1.28.5 and 1.29.x before 1.29.3. It doesn't sufficiently isolate long text content when the CKEditor 5 rich text editor is used. This allows a potential attacker to craft specialized HTML and JavaScript that may be executed when an administrator attempts to edit a piece of content. This vulnerability is mitigated by the fact that an attacker must have the ability to create long text content (such as through the node or comment forms) and an administrator must edit (not view) the content that contains the malicious content. This problem only exists when using the CKEditor 5 module.
Severity ?
4.4 (Medium)

Summary
An XSS issue was discovered in Backdrop CMS 1.28.x before 1.28.5 and 1.29.x before 1.29.3. It does not sufficiently validate uploaded SVG images to ensure they do not contain potentially dangerous SVG tags. SVG images can contain clickable links and executable scripting, and using a crafted SVG, it is possible to execute scripting in the browser when an SVG image is viewed. This issue is mitigated by the attacker needing to be able to upload SVG images, and that Backdrop embeds all uploaded SVG images within <img> tags, which prevents scripting from executing. The SVG must be viewed directly by its URL in order to run any embedded scripting.
