|---|---|---|---|---|---|---|
| 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 | 30.68% | 2025-02-03 | 2026-01-23 |
| CVE-2024-54123 | Backdrop CMS before 1.28.4 and 1.29.x before 1.29.2 allows XSS via an SVG document, if the SVG tag is allowed for a text format. | [email protected] | 6.1 | 0.57% | 2024-11-29 | 2026-04-06 |
| 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 |
| CVE-2022-42095 | Backdrop CMS version 1.23.0 was discovered to contain a stored cross-site scripting (XSS) vulnerability via the Page content. | [email protected] | 4.8 | 10.91% | 2022-11-23 | 2025-04-28 |

| CVE-2022-42092 | Backdrop CMS 1.22.0 has Unrestricted File Upload vulnerability via 'themes' that allows attackers to Remote Code Execution. Note: Third parties dispute this and argue that advanced permissions are required. | [email protected] | 7.2 | 3.96% | 2022-10-07 | 2024-11-21 |
| CVE-2022-34530 | An issue in the login and reset password functionality of Backdrop CMS v1.22.0 allows attackers to enumerate usernames via password reset requests and distinct responses returned based on usernames. | [email protected] | 5.3 | 0.24% | 2022-08-01 | 2024-11-21 |
| CVE-2019-19903 | An issue was discovered in Backdrop CMS 1.14.x before 1.14.2. It doesn't sufficiently filter output when displaying file type descriptions created by administrators. An attacker could potentially craft a specialized description, then have an administrator execute scripting when viewing the list of file types, aka XSS. This vulnerability is mitigated by the fact that an attacker must have a role with the "Administer file types" permission. | [email protected] | 4.8 | 0.35% | 2019-12-19 | 2024-11-21 |
| CVE-2019-19902 | An issue was discovered in Backdrop CMS 1.13.x before 1.13.5 and 1.14.x before 1.14.2. It 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 | [email protected] | 7.2 | 0.61% | 2019-12-19 | 2024-11-21 |

It doesn't sufficiently filter output when displaying certain block descriptions created by administrators. An attacker could potentially craft a specialized description, then have an administrator execute scripting when configuring a layout, aka XSS. This issue is mitigated by the fact that the attacker would be required to have the permission to create custom blocks, which is typically an administrative task | [email protected] | 4.8 | 0.35% | 2019-12-19 | 2024-11-21 |
| CVE-2019-19900 | An issue was discovered in Backdrop CMS 1.13.x before 1.13.5 and 1.14.x before 1.14.2. It doesn't sufficiently filter output when displaying content type names in the content creation interface. An attacker could potentially craft a specialized content type name, then have an editor execute scripting when creating content, aka XSS. This vulnerability is mitigated by the fact that an attacker must have a role with the "Administer content types" permission. | [email protected] | 4.8 | 0.35% | 2019-12-19 | 2024-11-21 |
| CVE-2019-14771 | Backdrop CMS 1.12.x before 1.12.8 and 1.13.x before 1.13.3 allows the upload of entire-site configuration archives through the user interface or command line.
