Description
Impact
A path traversal (directory traversal) vulnerability affects fides versions lower than 2.15.1, allowing remote attackers to access arbitrary files on the fides webserver container's filesystem.
Patches
The vulnerability is patched in fides 2.15.1. Users should upgrade to this version.
Workarounds
If the Fides webserver API is not directly accessible to attackers and is instead deployed behind a reverse proxy as recommended in Ethyca's security best practice documentation, and the reverse proxy is an AWS application load balancer, the vulnerability can't be exploited by these attackers. An AWS application load balancer will reject this attack with a 400 error.
Additionally, any secrets supplied to the container using environment variables rather than a fides.toml configuration file are not affected by this vulnerability.
