CVE-2026-56255
Capgo before 12.128.2 contains a denial of service vulnerability in the POST /app/demo endpoint that allows authenticated users with org write permissions to create unlimited demo applications without rate limiting or quota enforcement.
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
