CVE-2026-75930Network attack vector

Subscriber-level post overwrite via unchecked campaign_post authorization

Published Aug 25, 2026 · Updated Aug 25, 2026

Authorization bypass in Roxnor FundEngine 1.8.1 and earlier allows remote authenticated users to modify arbitrary WordPress posts and pages. The campaign_post handler accepts attacker-selected post identifiers, titles, content, and post_author values without verifying post-edit authority. Subscriber-level access and a REST nonce available to any logged-in account are sufficient to overwrite site content and seize post ownership.
