## What is CVE-2022-24849?

CVE-2022-24849 is a medium-severity vulnerability in Aiko-IT-Systems DisCatSharp, published on 14 Apr 2022. 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

DisCatSharp is a Discord API wrapper for .NET. Users of versions 9.8.5, 9.8.6, 9.9.0 and previously published prereleases of 10.0.0 who have used either one of the two `RequireDisCatSharpDeveloperAttribute`s or the `BaseDiscordClient.LibraryDeveloperTeam` have potentially had their bot token sent to a web server not affiliated with Discord. This server is owned and operated by DisCatSharp's development team. The tokens were not logged, yet it is still advisable to reset the tokens of potentially affected bots. 9.9.1 has been released to patch the issue for the current stable release and the current 10.0.0 prereleases are also no longer affected. Users unable to upgrade should remove all uses of the two `RequireDisCatSharpDeveloperAttribute`s and all direct calls to `BaseDiscordClient.LibraryDeveloperTeam`.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

- DisCatSharp (NuGet): affected from 9.8.5; fixed in 9.9.1

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.
