CVSS v3.1
8.7
High
| Vector | AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
ZITADEL versions prior to 2.38.2
ZITADEL versions prior to 2.39.2
Description
ZITADEL is an identity infrastructure management system where users can upload their own avatar image using various image types, including SVG. SVG can include scripts, such as javascript, which can be executed during rendering. Due to a missing security header, an attacker could inject code to an SVG to gain access to the victim’s account in certain scenarios. A victim would need to directly open the malicious image in the browser, where a single session in ZITADEL needs to be active for this exploit to work. If the possible victim had multiple or no active sessions in ZITADEL, the attack would not succeed.
Recommendations
For versions prior to 2.38.2, update to version 2.38.2 or later to resolve the issue.
For versions prior to 2.39.2, update to version 2.39.2 or later to resolve the issue.
As a temporary workaround, consider restricting the upload of SVG images or disabling the rendering of SVG images in the browser until a patch is applied.
