Prior to 3.0.18, early return on missing user during login flow allowed an attacker to enumerate valid user accounts via response timing discrepancy. When an email address existed in the database, the backend performed a bcrypt password comparison before returning a 401 Unauthorized, adding ~370 ms of latency. When the email did not exist, the backend returned immediately (~10 ms). This ~14\u00d7 timing difference could be detected without any difference in HTTP status codes or response bodies. This vulnerability is fixed in 3.0.18.<\/p>\n<p>  Severity: 5.3 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-45410 Published : May 28, 2026, 10:17 p.m. | 15\u00a0minutes ago Description :TREK is a collaborative travel planner.
