CVE-2026-97877

Status: DeferredMedium (5.5)—

A vulnerability was determined in zhistaredu StarTraining up to 3.8.1. This issue affects the function UserLoginService.createToken of the file application.yml of the component JWT Token Handler. This manipulation of the argument user_id/company_id causes use of hard-coded password. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
