Low risk6th percentile - higher than 6% of all known CVEs
Summary
Szafir accepts any client or server certificate without performing certificate and hostname validation, allowing HTTPS connections without authenticating the remote server. An attacker can provide an arbitrary SSL/TLS certificate and cause the application to download an update file from their server.
Risk Assessment
The organization is exposed to man-in-the-middle attacks and delivery of malicious updates, which can lead to workstation compromise. The lack of certificate validation completely defeats the protection provided by TLS.
Recommendation
Update Szafir to version 2.0 build 708 or later, which fixes the issue. Until then, restrict trust in update sources and monitor outbound traffic.

See all- CVE-2026-93571Low
Szafir is vulnerable to Path Traversal in the uploaded filename. A man-in-the-middle attacker who can reroute update requests to their server can prepare an arbitrary XML file that will be saved in a location chosen by the attacker. This issue was fixed in version 2.0 build 708.
- CVE-2026-93570High
Szafir and Szafir Weryfikująca are vulnerable to XML External Entity (XXE) injection. When a user signs or verifies a crafted XML file containing a DOCTYPE with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem. This issue was fixed in Szafir version 2.0 build 708. Szafir Weryfikująca is no longer supported (End of Life) and has not been fixed.
