CVE-2026-34026 — Path traversal in Wertheim SafeController Software allows authenticated users to download arbitrary files

Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains a path traversal vulnerability in the documentName parameter of the /safe/selfservice/openselfservicedocument endpoint. The application constructs a file path using attacker-controlled input without sufficient validation, allowing an authenticated attacker with any role or permission level to traverse out of the intended document directory and download arbitrary files accessible to the application. This includes, but is not limited to, application log files containing sensitive information and application binaries.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.5% (30-day exploitation probability)+6
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
