Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.

Description

When running in debug mode and the debug-embed (off by default) feature is not enabled, the generated get method does not check that the input path is a child of the folder given.

This allows attackers to read arbitrary files in the file system if they have control over the filename given. The following code will print the contents of your /etc/passwd if adjusted with a correct number of ../s depending on where it is run from.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rust-embed, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update rust-embed to 6.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xrg3-hmf3-rvgw is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
