Real-World Exposure
DisCatSharpReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects NuGet packages — download data is not available via public APIs for these ecosystems.
Description
Impact
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 RequireDisCatSharpDeveloperAttributes 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.
Patches
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.
Workarounds
Remove all uses of the two RequireDisCatSharpDeveloperAttributes and all direct calls to BaseDiscordClient.LibraryDeveloperTeam.
Details
The HttpClient responsible for sending requests to the Discord API was erroneously reused to send requests to our website when DisCatSharp's team members were to be fetched.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for DisCatSharp, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update DisCatSharp to 9.9.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24849 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
