CVE-2019-12437Network attack vector

Cross-site request forgery via leading GraphQL fragment

Published Feb 19, 2020 · Updated Aug 4, 2024

CSRF in Silverstripe GraphQL before 2.0.5 and 3.1.2 allows remote attackers to execute mutations through an authenticated user session. The GraphQL mutation check treats a leading fragment as non-mutating, so middleware accepts the request without an X-CSRF-TOKEN header. Exploitation requires user interaction and an authenticated browser session; successful mutations can alter or delete data permitted to that user.
