CVE-2026-126042
VNote 3.11.0 before 4.12.0 OS Command Injection via Tasks Magic Variables
VNote 3.11.0 before 4.12.0 contains an OS command injection vulnerability in its Tasks feature: magic variables such as ${bufferName} and ${selectedText} are substituted into a shell command string without escaping. Attackers can share a notebook containing a note whose filename or text includes shell metacharacters such as $(...), backticks, ; or |, executing commands as the victim when they run a task referencing these variables.
