CVE-2026-89286Network attack vectorHinoki check available

Unauthenticated data disclosure via publicly accessible logs

Published Oct 19, 2026 · Updated Oct 19, 2026

Log exposure in NexPlugs FormFlow for GoHighLevel 1.0.0 and earlier allows remote attackers to read CRM data via unauthenticated requests. The WordPress plugin writes connected-CRM identifiers and a third-party access token to a log in the publicly accessible uploads directory without restricting access. Token disclosure requires a linked integration and a reachable log; the established impact is disclosure of its contents, not execution on the WordPress host.
