Authorization bypass via overwritten post-resolver check
Published Mar 24, 2025 · Updated Mar 24, 2025
Authorization bypass in API Platform Core 3.3.8 through 3.3.14 allows remote authenticated users to access or alter protected data. AccessCheckerProvider::provide selects securityAfterResolver for the GraphQL resolver stage, but a missing break falls through to the default case and overwrites that expression with security. The bypass requires a GraphQL operation configured only with securityAfterResolver and high-privileged API access; it can expose or alter data that the post-resolver rule protects.
