## What is CVE-2026-1958?

CVE-2026-1958 is a high-severity vulnerability in BRI KlinikaXP, published on 23 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-798 (Use of Hard-coded Credentials)

What it is: CVE-2026-1958 is a high-severity vulnerability in BRI KlinikaXP, published on 23 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-1958 in the wild and no public exploit code.

Affected product: BRI KlinikaXP. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
