Api Platform Json Api
Monthly
Cross-user attribute structure leakage in API Platform Core's JSON:API and HAL serializers exposes the schema layout of security-gated properties to lower-privileged users through improper cache reuse. Versions from 2.6.0 up to 4.1.29, 4.2.26, and 4.3.12 are affected across the core, hal, and json-api packages. The component structure computed for a higher-privileged user's request can be served from cache to a subsequent lower-privileged user's request, bypassing the per-request evaluation of #[ApiProperty(security: ...)] predicates. No public exploit identified at time of analysis; vendor-released patches are available.
