CVE-2023-4645Network attack vector

Sensitive-data disclosure via missing ai_ajax authorization

Published Oct 19, 2023 · Updated Apr 8, 2026

Missing authorization in the ai_ajax function in Spacetime Ad Inserter 2.7.30 and earlier allows remote attackers to read sensitive data. The function returns post titles and slugs, protected-post passwords, usernames, roles, and the plugin license key without an authorization check. Remote debugging must be enabled for the license key to be exposed, and that option is disabled by default.
