NVD CRITICAL 9.1 · published 2026-08-28 · 2 on the wire

An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG.

If an attacker can manipulate system configuration parameters, this enables the execution of arbitrary Java bytecode residing on the application classpath under the security context of the PaperCut server process.
