What is CVE-2026-33793?

A vulnerability in the user interface (UI) of Juniper Networks Junos OS and Junos OS Evolved enables a local, low-privileged attacker to escalate privileges to root. When a configuration permits unsigned Python op scripts, a non-root user can execute harmful op scripts, gaining root-equivalent access and compromising the system's integrity. This includes multiple versions across both Junos OS and Junos OS Evolved, making it crucial for users to apply the latest updates to mitigate this security risk.

Affected Version(s)

Junos OS 0 < 22.4R3-S7

Junos OS 23.2 < 23.2R2-S4

Junos OS 23.4 < 23.4R2-S6
