CVE-2026-103526

Published Oct 12, 2026 CVSS 3.1 · 3.7 Low EPSS < 1% KEV · Not listed
Description
In Thelia v2.6.0, both the administrative login and forgotten password endpoints return different responses for invalid usernames and incorrect passwords, allowing unauthenticated attackers to enumerate valid administrator accounts. Because the endpoint also lacks rate limiting or other protections against repeated authentication attempts, username enumeration can be performed efficiently at scale.
