## What is GHSA-8c8c-4vfj-rrpc?

GHSA-8c8c-4vfj-rrpc is a cross-site scripting vulnerability in redis-commander, published on 1 Sep 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Affected versions of `redis-commander` contain a cross-site scripting vulnerability in the `highlighterId` paramter of the clipboard.swf component on hosts serving Redis Commander.

Mitigating factors:
Flash must be installed / enabled for this to work. The below proof of concept was verified to work using Firefox 57.0 on Windows 10 by manually installing the [Flash NPAPI Windows plugin](https://get.adobe.com/flashplayer/otherversions/)

What it is: GHSA-8c8c-4vfj-rrpc is a cross-site scripting vulnerability in redis-commander, published on 1 Sep 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of GHSA-8c8c-4vfj-rrpc in the wild and no public exploit code.

Affected packages and fixed versions:
- redis-commander (npm): affected from 0.0.0; fixed in 0.5.0
- redis-commander (npm): affected from 0.0.0; fixed in 0.5.0

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.
