Name of the Vulnerable Software and Affected Versions Firefly III versions prior to 4.7.17.3

Description The issue is related to stored XSS due to the lack of filtration of user-supplied data in image file content. The JavaScript code is executed during attachments/view/$file id$ attachment viewing. It is noted that an attacker must have the same access rights as the user to execute the vulnerability.

Recommendations For versions prior to 4.7.17.3, update to version 4.7.17.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the attachments/view/$file id$ endpoint to minimize the risk of exploitation. Avoid using user-supplied data in image file content until the issue is resolved.
