Information disclosure in affected PaperCut NG/MF releases allows remote authenticated users to read server files via a crafted API request. PaperCut identifies a specially formed API payload and CWE-76, but has not disclosed the endpoint, affected parser, or incorrect code operation. Exploitation requires reconnaissance to obtain a system token, applies only to Linux and macOS servers, and has no reported impact beyond file confidentiality.
