Preliminary research
Bypassing Apache FOP PostScript escaping to reach Ghostscript
AI-collected research leads through 2 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.
Finds an escaping mismatch in Apache FOP's PostScript output that lets attacker-controlled XML inject executable PostScript commands. The write-up develops delimiter and whitespace bypasses and shows how the primitive can be chained with Ghostscript file-system access or a sandbox escape.
