CVE-2026-123276 · Package
NO FIX YET · SEE WHAT TO DO
In JetBrains CLion before 2026.3 and 2026.2.4.1, a crafted GDB server debug profile could execute code even while Safe Mode was on. An attacker who gets a developer to open a malicious project or profile could run commands on that developer's machine.

It checks your repository and tells you if you’re affected, with the fix.
Developers who use JetBrains CLion and open projects from sources they do not fully trust, since the flaw is triggered by a crafted debug profile in the project. Teams that only open their own version-controlled projects and do not run unknown debug configurations have a lower exposure. The sources do not describe a server-side or network-reachable path.
