CVE-2026-109703

WPGraphQL before 2.24.1 contains a missing authorization vulnerability in the createComment mutation that allows unauthenticated attackers to comment on non-public posts by bypassing post status checks. An attacker can attach comments to draft, private, trashed or password-protected posts to leak hidden titles via moderator notifications, enumerate post IDs and backdate comments or mark them as pingbacks.

WPGraphQL before 2.24.1 contains a missing rate limiting vulnerability that allows unauthenticated attackers to flood password reset emails by aliasing the sendPasswordResetEmail mutation. An attacker can send one HTTP request with many aliases, bypassing batch_limit, to exhaust mail provider quota and repeatedly rotate reset keys, blocking legitimate password recovery.

WPGraphQL before 2.24.2 contains an information disclosure vulnerability that allows unauthenticated attackers to determine object existence through distinct error responses. An attacker can iterate IDs against deleteMediaItem, updateMediaItem, deleteComment and updateComment mutations to discover hidden draft, private, trashed posts, custom post types and unapproved comments.

The WPGraphQL plugin for WordPress prior to 2.22.2 does not enforce object-level capabilities in the updatePost mutation. An authenticated Contributor can publish their own drafts without editorial approval or modify their own previously published posts despite lacking edit_published_posts.

In WPGraphQL for WordPress versions 2.0.0 to 2.15.1, the deprecated user field on SendPasswordResetEmailPayload lets an unauthenticated caller distinguish existing author-class accounts and obtain public profile fields.

WPGraphQL versions below 2.11.1 are vulnerable to unauthenticated SQL Injection.

A Cross-Site Request Forgery (CSRF) vulnerability in WPGraphQL allows attackers to perform unauthorized actions. This issue affects WPGraphQL from n/a through 2.5.3.
