Summary

Golf may allow attacker to bypass CSRF protections due to weak PRNG

Details

CSRF tokens are generated using math/rand, which is not a cryptographically secure random number generator, allowing an attacker to predict values and bypass CSRF protections with relatively few requests.

Severity

8.8 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
