Security readout for executives and security teams
Plain-English summary
CVE-2021-29493 affects the Tickets module in kennnyshiwa-cogs for Red Discordbot. A Discord user with access to the bot could send a crafted message that exposes sensitive information. The published scoring emphasizes confidentiality impact, not service outage or data modification.
Executive priority
Handle as a moderate-priority confidentiality issue. It is not listed as KEV, but affected Discord bots may expose sensitive operational data to low-privileged Discord users. Patch or disable the module promptly where the cog is deployed.
Technical view
The issue is classified as CWE-94 and scored CVSS 3.1 6.5. The vulnerable component is kennnyshiwa-cogs before commit 5a84d60018468e5c0346f7ee74b2b4650a6dade7. Attack prerequisites are low, network-reachable Discord interaction, and low privileges. Sources name the Tickets module and a patched commit.
Likely exposure
Exposure is limited to Red Discordbot deployments using kennnyshiwa-cogs with the Tickets module loaded and code older than the patched commit. Organizations not running this Discord bot cog are not indicated as affected by the provided sources.
Exploitation context
The source bundle says an exploit was found, but KEV is false and no cited source confirms active exploitation in the wild. The available evidence supports treating this as a known, message-triggered confidentiality risk rather than confirmed widespread exploitation.
Researcher notes
The public details identify the affected module, CWE-94 classification, CVSS vector, patched commit, and unload workaround. They do not provide enough evidence to claim integrity or availability impact, active exploitation, or affected products beyond kennnyshiwa-cogs for Red Discordbot.
Mitigation direction
- Upgrade kennnyshiwa-cogs to commit 5a84d60018468e5c0346f7ee74b2b4650a6dade7 or later.
- Unload the Tickets module until the patched version is deployed.
- Review the GitHub advisory for any vendor-maintained update guidance.
- Prioritize bots in servers where untrusted users can interact with Tickets.
Validation and detection
- Inventory Red Discordbot instances for kennnyshiwa-cogs usage.
- Confirm whether the Tickets module is loaded on each bot.
- Verify installed code is at or after commit 5a84d60018468e5c0346f7ee74b2b4650a6dade7.
- Review bot configuration for sensitive data exposed to cog runtime access.
- Check available bot logs for unusual Tickets interactions without reproducing the exploit.
