AI-suggested
Upgrade to Concrete CMS Community Store version 2.7.8 or later, where the token generation method has been corrected to use secure random values. Patch status is confirmed by the version range indicating affected versions are prior to 2.7.8.
Description
Concrete CMS Community Store before 2.7.8 derives digital product download tokens from order creation timestamps instead of random values, making tokens predictable. Unauthenticated attackers can enumerate sequential order and file identifiers to calculate valid download tokens and retrieve digital goods purchased by other customers.
