CVE-2026-40505
Description
A flaw was found in MuPDF mutool. This vulnerability allows a local attacker to embed malicious ANSI escape sequences within a PDF's metadata. When a user views the PDF's information using the mutool info command, these unsanitized sequences are processed by the terminal. This can lead to the terminal displaying arbitrary text, which could be used for social engineering attacks, such as presenting fake prompts or spoofed commands to deceive the user.
