AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N

Name of the Vulnerable Software and Affected Versions Firefly III version 4.7.17.3

Description The issue allows an attacker to enumerate local files due to the lack of protocol scheme sanitization, such as for file:/// URLs. This is related to fints url in import/job/configuration and import/create/fints.

Recommendations For Firefly III version 4.7.17.3, consider restricting access to the fints url parameter in the import/job/configuration and import/create/fints endpoints to minimize the risk of exploitation. Additionally, as a temporary workaround, consider sanitizing the protocol scheme for file:/// URLs to prevent local file enumeration.
