CVE-2025-55319: Agentic AI and Visual Studio Code Remote Code Execution Vulnerability

Noroxi assessment

Priority: Monitor (action score 39/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.95% (FIRST EPSS); higher than 61.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Visual Studio Code 1.104.0.

Low priority for now. Upgrade to Visual Studio Code 1.104.0 or later.
