CVE-2025-65899: Difuse Kalmia

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

Kalmia CMS version 0.2.0 contains a user enumeration vulnerability in its authentication mechanism. The application returns different error messages for invalid users (user_not_found) versus valid users with incorrect passwords (invalid_password). This observable response discrepancy allows unauthenticated attackers to enumerate valid usernames on the system.
