TIMELINE Jul 20 Reserved by WPScan Aug 2 Published (CNA: WPScan) Aug 3 EXPLOIT PUBLISHED — CVE-2026-16261 (Unknown login-social). Public exploit reference added.
The login-social WordPress plugin through 1.0.4 does not validate password-reset requests against a reset key or the requester's identity, and it issues authentication sessions from unverified third-party sign-in data, allowing unauthenticated attackers to reset any user's password or log in as any existing account, including administrators, and take over the site.
