What to do
AI-suggested
To mitigate CVE-2025-69871, organizations should immediately upgrade MedusaJS to a version where this race condition is fixed once available. In the absence of an official patch, implement concurrency controls such as database-level locking or atomic transactions around the registerUsage() function to ensure the read-check-update sequence is atomic. Employ rate limiting and request throttling on checkout endpoints to reduce the feasibility of concurrent exploitation attempts. Monitor logs for unusual patterns of promotional code usage, especially rapid or simultaneous redemptions. Consider implementing additional server-side validation to cross-check usage counts before finalizing transactions. Engage with the MedusaJS community or maintainers to track patch releases and security advisories. Finally, conduct thorough testing of promotion modules under concurrent load to detect similar race conditions proactively.
Description
A race condition vulnerability exists in MedusaJS Medusa v2.12.2 and earlier in the registerUsage() function of the promotion module. The function performs a non-atomic read-check-update operation when enforcing promotion usage limits. This allows unauthenticated remote attackers to bypass usage limits by sending concurrent checkout requests, resulting in unlimited redemptions of limited-use promotional codes and potential financial loss.
