CVE-2026-54768 PUBLISHED

WPGraphQL has deprecated `user` field on SendPasswordResetEmailPayload that leaks user existence + profile (defeats explicit anti-enumeration design)

Assigner: GitHub_M
Reserved: 15.06.2026 Published: 31.07.2026 Updated: 31.07.2026

WPGraphQL provides a GraphQL API for WordPress sites. From 2.0.0 until 2.15.1, the deprecated user field on SendPasswordResetEmailPayload lets an unauthenticated caller distinguish existing author-class accounts through the sendPasswordResetEmail mutation and obtain public profile fields. This issue is fixed in version 2.15.1.
