CVE-2026-40505 · MuPDF < 1.27 mutool ANSI Injection via Metadata

This page contains facts from public vulnerability sources. Check the original advisory before updating.

MuPDF before 1.27 contains an ANSI injection vulnerability in mutool that allows attackers to inject arbitrary ANSI escape sequences through crafted PDF metadata fields. Attackers can embed malicious ANSI escape codes in PDF metadata that are passed unsanitized to terminal output when running mutool info, enabling them to manipulate terminal display for social engineering attacks such as presenting fake prompts or spoofed commands.
