CVE-2025-45731 2fauth vulnerability CVSS: 0 24 Jul 2025, 14:15 UTC

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.

CVE-2024-52598 2fauth vulnerability CVSS: 0 20 Nov 2024, 15:15 UTC

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 looks like an image. Additionally, the library does some basic validation on the URI, attempting to filter our URIs which do not have an image extension. However, this can be easily bypassed by appending the string `#.svg` to the URI. The combination of these two issues allows an attacker to retrieve URIs accessible from the application, as long as their content type is text based. If not, the request is still sent, but the response is not reflected to the attacker. Version 5.4.1 fixes the issues.

CVE-2024-52597 2fauth vulnerability CVSS: 0 20 Nov 2024, 14:15 UTC

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 compromise that victim's session and access to their tokens. Version 5.4.1 contains a patch for the issue.

CVE-2023-36816 2fauth vulnerability CVSS: 0 03 Jul 2023, 17:15 UTC

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.
