Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In DisCatSharp, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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 `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. ### 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 `RequireDisCatSharpDeveloperAttribute`s 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. ### For more information If you have any questions or comments about this advisory: * Join our [Discord server](https://discord.gg/GGYSywkxwN) * Email us at [ottero@aitsys.dev](mailto:ottero@aitsys.dev)
