CVE-2026-0236: Prisma Browser: Code Injection Enables Security Controls Bypass

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Palo Alto Networks Prisma Browser 146.16.6.165.

Low priority for now. Upgrade to Palo Alto Networks Prisma Browser 146.16.6.165 or later.
