Attackers Chain Two PaperCut Flaws to Execute Code Without Authentication

Malicious actors are exploiting a newly patched security flaw in PaperCut NG and MF to execute arbitrary code on susceptible instances, as the company released a fresh emergency fix with additional hardening. "This vulnerability gives an unauthenticated attacker remote control over PaperCut's...

EUVD-2026-67714

An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG. The application instantiates database driver classes based on configurable driver names without validating against an allowlist of approved drivers. If an attacker can...

CVE-2026-82078 PaperCut MF/NG: Unsafe Dynamic Class Loading in Database Connector

An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG. The application instantiates database driver classes based on configurable driver names without validating against an allowlist of approved drivers. If an attacker can...

CVE-2026-82078

CVE-2026-82078 is an unsafe dynamic class loading vulnerability (CWE-470, CVSS 9.4 Critical) in the database connection utilities of PaperCut NG and PaperCut MF . The application instantiates database driver classes from configurable names without an allowlist, allowing arbitrary Java bytecode to...

VulnCheck KEV: CVE-2026-82078

An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG. The application instantiates database driver classes based on configurable driver names without validating against an allowlist of approved drivers. If an attacker can...

EUVD-2026-26483

The LabOne Q serialization framework uses a class-loading mechanism importcls to dynamically import and instantiate Python classes during deserialization. Prior to the fix, this mechanism accepted arbitrary fully-qualified class names from the serialized data without any validation of the target...
