## What is GHSA-7x92-2j68-h32c?

GHSA-7x92-2j68-h32c is a path traversal vulnerability in featurebook, published on 1 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Affected versions of `featurebook` resolve relative file paths, resulting in a directory traversal vulnerability. A malicious actor can use this vulnerability to access files outside of the intended directory root, which may result in the disclosure of private files on the vulnerable system.

The `featurebook` package is not intended to be run in production code nor to be exposed to an untrusted network.

## Proof of Concept
```
GET /../../../../../../../../../../etc/passwd HTTP/1.1
host:foo
```

## Recommendation

No direct patch is currently available.

At this time, the best mitigation is to ensure that `featurebook` is not running in production or exposed to an untrusted network.

## Which versions are affected by GHSA-7x92-2j68-h32c?

2 open source packages ship an affected version, including featurebook.


| Package | Ecosystem | Affected | Fixed in |
| --- | --- | --- | --- |

Affected packages and fixed versions:
- featurebook (npm): affected all versions; no fix listed
- featurebook (npm): affected all versions; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
