Low risk20th percentile - higher than 20% of all known CVEs
Summary
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.
Risk Assessment
An attacker can read arbitrary files from the victim's system, potentially leading to leakage of sensitive data such as cryptographic keys or personal information.
Recommendation
Update Szafir to version 2.0 build 708 or later; for Szafir Weryfikująca, which is unsupported, discontinue use or implement compensating controls (e.g., XML file validation).
Other vulnerabilities in Szafir
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-2026-106036Medium
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.
Original NVD description (English source)
Szafir and Szafir Weryfikująca are vulnerable to XML External Entity (XXE) injection. When a user signs or verify 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.
