Publication date 3 May 2025
Last updated 29 October 2025
Ubuntu priority
Description
Mojolicious versions from 7.28 for Perl will generate weak HMAC session cookie secrets via "mojo generate app" by default When creating a default app skeleton with the "mojo generate app" tool, a weak secret is written to the application's configuration file using the insecure rand() function, and used for authenticating and protecting the integrity of the application's sessions. This may allow an attacker to brute force the application's session keys.
