CVE-2026-46347: CWE-330: Use of Insufficiently Random Values in intranda goobi-viewer-core
Description
CVE-2026-46347 affects the intranda goobi-viewer-core web application prior to version 26.05. The vulnerability involves the generation of password reset links with insufficient randomness, allowing an attacker to potentially brute-force the replacement password if they can approximate the server-side generation time. Exploitation requires the victim to have initiated the password reset and the attacker to infer server time from metadata. This issue has been fixed in version 26.05.

Technical Analysis
The Goobi viewer web application prior to version 26.05 generates replacement passwords for password reset links using insufficiently random values. This predictable password generation allows an attacker who can estimate the server-side generation time to brute-force the replacement password. Exploitation requires the victim to have triggered the reset and the attacker to infer server time from network or email metadata. The vulnerability is identified as CWE-330 (Use of Insufficiently Random Values) and has been patched in version 26.05.
Potential Impact
An attacker who can approximate the server-side generation time and whose victim has initiated a password reset may brute-force the replacement password, potentially leading to account compromise. The vulnerability impacts confidentiality and integrity but does not affect availability. The CVSS 3.1 base score is 6.8 (medium severity), reflecting network attack vector, high attack complexity, no privileges required, user interaction required, and high impact on confidentiality and integrity.
Mitigation Recommendations
This vulnerability has been patched in intranda goobi-viewer-core version 26.05. Users should upgrade to version 26.05 or later to remediate the issue. No additional mitigation is required once the patch is applied.
