CVE-2026-19718Network attack vector

Unauthenticated site takeover via weak connection keys

Published Aug 26, 2026 · Updated Aug 26, 2026

Authentication bypass in three BlogVault WordPress plugins before 6.65 allows remote attackers to gain site administrator access. The connection mechanism exposes data derived from the site-binding secret and generates that secret with a weak pseudo-random number generator. No authentication is required; recovering the connection key permits administrative control of the linked WordPress site.
