CVE-2026-46347: Intranda Goobi viewer weak password generation in reset flow

CVE-2026-46347 · Severity: medium · CVSS 6.8 · Published 2026-10-23

Goobi viewer is a web application for displaying digitized library materials. Prior to version 26.05, the application generates password reset tokens with insufficient randomness, allowing an attacker who observes the approximate time of a password reset request to brute-force the new password. An attacker would need the victim to initiate a password reset and would need to infer the server time from network metadata or email timestamps.

Technologies: Intranda Goobi viewer. Vendors: Intranda.

How to fix

Fixed in: 26.05

Technical details

The vulnerability is weak entropy in password generation during the password reset flow. The application generated reset passwords from only 4 bytes of random data encoded as 8 hex characters (~16 bits of entropy), and used predictable time-based seeding. An attacker with knowledge of the approximate reset time can enumerate possible passwords. The fix increases the random data to 7 bytes (56 bits of entropy) and replaces time-based generation with SecureRandom.
