## What is GHSA-fq3w-p4fg-mw73?

GHSA-fq3w-p4fg-mw73 is a denial of service vulnerability in fixurjavainstall, published on 25 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

### Impact
Affects: Anyone who generates the UNIX man pages in Fuji <= `0.8.0` build with the `dev` crate feature.
Consequences: `/usr/share/man/man8` may be entirely removed & re-created without any of the previous entries.

### Patches
At the time of writing, no new version has been released on crates.io, due to an unrelated CI/CD publishing issue.
Due to the same unrelated publishing issue, no new GitHub Releases version has been released.

### Workarounds
Do not run `fuji manual` on non-`dev` builds for versions <= `0.8.0`.

### Additional Information
This bug results from development-only code being accidentally left in for release use.
Previous versions of Fuji are still "safe" to use, provided that you do not run `fuji manual`.
There is no malicious potential from this, it's just a major annoyance to accidentally remove all your sysadmin man pages.

What it is: GHSA-fq3w-p4fg-mw73 is a denial of service vulnerability in fixurjavainstall, published on 25 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of GHSA-fq3w-p4fg-mw73 in the wild and no public exploit code.

Affected packages and fixed versions:
- fixurjavainstall (crates.io): affected all versions; fixed in 0.8.1
- fixurjavainstall (crates.io): affected all versions; fixed in 0.8.1

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.
