CVE-2026-35197Public exploit

Arbitrary command execution via eval-based template parsing

Published Apr 6, 2026 · Updated Apr 6, 2026

Code injection in dye 1.1.0 allows local users to execute arbitrary shell commands through crafted template expressions. The template parser re-executes text between double curly braces as dye commands, and dye_out passes capability arguments to eval without neutralizing shell metacharacters. Exploitation requires untrusted content to enter a template expression and a user or script to process it, causing commands to run with that script's privileges.
