CVE-2026-110638 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
doc-recog through 1.1.6 contains an OS command injection vulnerability that allows attackers to execute commands by supplying crafted document paths to recog() or tag(). Attackers can embed $(...) or backtick command substitution in the file path, which DocData._readPDF passes to a shell-based pdftotext exec call, running commands with Node.js process privileges.
