CVE-2026-46346: Goobi viewer predictable password reset token

CVE-2026-46346 · Severity: medium · CVSS 6.5 · Published 2026-10-23

Goobi viewer is a web application for displaying digitized content in browsers. An attacker who knows a user's email address can request a password reset and brute-force the reset token, since it is generated from predictable time-based values, allowing unauthorized account takeover.

Technologies: Intranda Goobi viewer. Vendors: Intranda.

How to fix

  • Fixed in: 26.05

Technical details

The password reset token is generated using SHA-256(currentTimeMillis), making it enumerable within a narrow time window. An attacker can request a password reset for a known email, then brute-force the token by trying all possible millisecond values around the request time. The generated password itself was also weak (SHA-256(currentTimeMillis).substring(0,8)), providing only ~10 bits of entropy. The fix replaces time-based generation with cryptographically secure random values via SecureRandom.
