## What is CVE-2020-15147?

CVE-2020-15147 is a high-severity code injection vulnerability in Cog-Creators Red-DiscordBot, published on 21 Aug 2020. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Red Discord Bot before versions 3.3.12 and 3.4 has a Remote Code Execution vulnerability in the Streams module. This exploit allows Discord users with specifically crafted "going live" messages to inject code into the Streams module's going live message. By abusing this exploit, it's possible to perform destructive actions and/or access sensitive information. As a workaround, unloading the Trivia module with `unload streams` can render this exploit not accessible. It is highly recommended updating to 3.3.12 or 3.4 to completely patch this issue.

Weakness: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), CWE-94 (Improper Control of Generation of Code)

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.
