Description
Payload is a free and open source headless content management system. Payload versions from 3.0.0 before 3.90.0 and canary versions from 4.0.0-canary.0 before 4.0.0-canary.34 use a lower-than-recommended PBKDF2 work factor for password hashing, reducing the computational effort required to test recovered password hashes. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
