GHSA-7mxx-3cgm-xxv3: api-platform/core (CVE-2025-23204)

Package	Ecosystem	Affected	Fixed in
api-platform/core	Packagist	>=3.3.8, <3.3.15	3.3.15

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

API Platform Core versions 3.3.8 before 3.3.15 have a GraphQL access-check bug: a security check meant to run after resolvers is replaced by another check because a switch clause lacks a break. Per the source, the impact applies only when a GraphQL operation has a security after resolver and no security check inside security, and the source gives few further details on exploitation. Upgrade api-platform/core to version 3.3.15, which is the listed fixed version.
