AI Analysis
Technical Summary
This vulnerability (CVE-2026-49382) affects JetBrains IntelliJ IDEA versions prior to 2026.1 and is related to template injection in the Copyright plugin, which can lead to code execution. The CVSS score of 4.5 reflects a medium severity with local attack vector and high attack complexity. The vulnerability does not require privileges but does require user interaction. No official fix or patch has been published yet, and no exploits are known to be active.
Potential Impact
