How to Fix GHSA-3227-r97m-8j95

To remediate this vulnerability, upgrade all affected Afire dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

afire fixed: 1.1.0 
Upgrade afire to 1.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for afire

How to Check if You Are Affected

To determine whether your application is affected by GHSA-3227-r97m-8j95, inspect your project dependencies for Afire:

inspect dependencies for afire

Analyze the terminal output to locate any version of Afire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-34: Path Traversal: '....//', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '....//' (doubled dot dot slash) sequences that can resolve to a location that is outside of that directory. In Afire, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact This vulnerability effects the built-in afire serve_static extension allowing paths containing `//....` to bypass the previous path sanitation and request files in higher directories that should not be accessible. ### Patches The issue has been fixed in [afire 1.1.0](https://crates.io/crates/afire/1.1.0). If you can, just update to the newest version of afire. ### Workarounds If you can't update afire you can simply disallow paths containing `/..` with the following middleware. Make sure this is the last middleware added to the server so it runs first, stopping the bad requests. ```rust use afire::prelude::*; struct PathTraversalFix; impl Middleware for PathTraversalFix { fn pre(&self, req: Request) -> MiddleRequest { if req.path.replace("\\", "/").contains("/..") { return MiddleRequest::Send( Response::new() .status(400) .text("Paths containing `..` are not allowed"), ); } MiddleRequest::Continue } } ``` ```rust let mut server = Server::new(host, port); PathTraversalFix.attach(&mut server); ``` ### References You can read about the new changes to afire in 1.1.0 [here](https://connorcode.com/writing/afire/update-3) ### For more information If you have any questions or comments about this advisory you can email me or message me on discord.
