How to Fix CVE-2020-15147
To remediate this vulnerability, upgrade all affected Red DiscordBot dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install Red-DiscordBot>=3.3.12Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show Red-DiscordBotHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2020-15147, inspect your installed packages using pip:
pip show Red-DiscordBotAnalyze the terminal output to locate any version of Red DiscordBot in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.12), your application is affected.
Note: The pip show Red-DiscordBot command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Red DiscordBot, 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.

By abusing this exploit, it's possible to perform destructive actions and/or access sensitive information.\n\n### Patches\nThis critical exploit has been fixed on version ``3.3.12`` & ``3.4``.\n\n### Workarounds\nUnloading the Streams module with ``unload streams`` can render this exploit not accessible. We still highly recommend updating to ``3.3.12`` or ``3.4`` to completely patch this issue.\n\n### References\n* https://github.com/Cog-Creators/Red-DiscordBot/pull/4183\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Cog-Creators/Red-DiscordBot](https://github.com/Cog-Creators/Red-DiscordBot)\n* Over on our [Discord server](https://discord.gg/red)",
