|---|---|---|---|---|---|---|
| CVE-2025-63828 | Host Header Injection vulnerability in Backdrop CMS 1.32.1 allows attackers to manipulate the Host header in password reset requests, leading to redirects to malicious domains and potential session hijacking via cookie injection. | [email protected] | 6.1 | 0.04% | 2025-11-18 | 2025-11-24 |
| CVE-2025-44141 | A Cross-Site Scripting (XSS) vulnerability exists in the node creation form of Backdrop CMS 1.30. | [email protected] | 6.1 | 0.17% | 2025-06-26 | 2026-03-04 |
| CVE-2025-25063 | 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 | [email protected] | 4.4 | 0.61% | 2025-02-03 | 2026-01-23 |
| CVE-2025-25062 | 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 | [email protected] | 4.4 | 36.86% | 2025-02-03 | 2026-01-23 |

| CVE-2023-31045 | 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 Fu | [email protected] | 4.8 | 0.21% | 2023-04-24 | 2026-04-06 |
