CVE-2026-2233
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the draft_post() function in all versions up to, and including, 4.2.8. This makes it possible for unauthenticated attackers to modify arbitrary posts (e.g. unpublish published posts and overwrite the contents) via the 'post_id' parameter.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe User Frontend WordPress plugin has a broken access control vulnerability in the draft_post() function, which lacks proper capability checks. This allows unauthenticated attackers to modify arbitrary posts by supplying a post_id parameter, enabling unpublishing of posts or content overwrite.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the plugin to a version beyond 4.2.8 once a patch is released. Until then, consider disabling the plugin or implementing WAF rules to block requests to the vulnerable endpoint.
