CVE-2023-36827: Fides vulnerable to Path Traversal in Webserver API
First published: Wed Jul 05 2023(Updated: )
### 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](https://docs.ethyca.com/docs/configuration/security-practices#reverse-proxy), 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.
