| CVE-2026-32133 | 2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Prior to 6.1.0, a blind SSRF vulnerability exists in 2FAuth that allows authenticated users to make arbitrary HTTP requests from the server to internal networks and cloud metadata endpoints. The image parameter in OTP URL is not properly validated for internal / private IP addresses before making HTTP requests. While the previous fix added response validation to ensure only valid images are | [email protected] | 7.8 | 0.07% | 2026-03-11 | 2026-03-13 |
| CVE-2025-45731 | A group deletion race condition in 2FAuth v5.5.0 causes data inconsistencies and orphaned accounts when a group is deleted while other operations are pending. | [email protected] | 6.5 | 0.33% | 2025-07-24 | 2026-01-20 |
| CVE-2024-52598 | 2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Two interconnected vulnerabilities exist in version 5.4.1 a SSRF and URI validation bypass issue. The endpoint at POST /api/v1/twofaccounts/preview allows setting a remote URI to retrieve the image of a 2fa site. By abusing this functionality, it is possible to force the application to make a GET request to an arbitrary URL, whose content will be stored in an image file in the server if it l | [email protected] | 7.5 | 0.17% | 2024-11-20 | 2025-08-04 |
| CVE-2024-52597 | 2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Versions prior to 5.4.1 are vulnerable to stored cross-site scripting due to improper headers in direct access to uploaded SVGs. The application allows uploading images in several places. One of the accepted types of image is SVG, which allows JS scripting. Therefore, by uploading a malicious SVG which contains JS code, an attacker which is able to drive a victim to the uploaded image could | [email protected] | 6.1 | 0.83% | 2024-11-20 | 2025-08-04 |
| CVE-2023-36816 | 2FA is a Web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Cross site scripting (XSS) injection can be done via the account/service field. This was tested in docker-compose environment. This vulnerability has been patched in version 4.0.3. | [email protected] | 6.1 | 0.53% | 2023-07-03 | 2024-11-21 |
