What is CVE-2026-126042?

VNote versions prior to 4.12.0 are susceptible to an OS command injection vulnerability within the Tasks feature. This issue arises from the improper handling of magic variables like ${bufferName} and ${selectedText} in shell command strings. Malicious actors can embed shell metacharacters within a note's filename or text, which, when executed by a user, can lead to the unintended execution of commands on the victim’s system. Users are recommended to upgrade to version 4.12.0 or later to mitigate this risk.

Affected Version(s)

VNote 3.11.0 < 4.12.0
