Password cracking via single-round SHA-256 hashes
Published Mar 27, 2024 · Updated Aug 2, 2024
Insufficient password hashing in Serverpod before 1.2.6 allows attackers to crack stored passwords after database compromise. Emails.generatePasswordHash performs one SHA-256 operation over the password and a shared server salt, optionally adding the email address, without a per-hash random salt or work factor. Exploitation requires access to the authentication database; the resulting exposure is limited to recoverable account passwords.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <1.2.6
- Affected versionversion=< 1.2.6
