CVE-2020-16253 — Vulnerability in pghero — CVE Details

HIGH

PgHero gem allows CSRF

Published August 5, 2020Updated February 16, 2024Source: osv

Summary

The PgHero gem through 2.6.0 for Ruby allows CSRF. PgHero normally uses the `protect_from_forgery` method from Rails to prevent CSRF. However, this defaults to `:null_session`, which has no effect on non-session based authentication methods. Thus the ruby gem is vulnerable with non-session based authentication methods like basic authentication.
