CVE-2026-16261: CWE-287 Improper Authentication in login-social
The login-social WordPress plugin through version 1.0.4 contains an improper authentication vulnerability. It fails to validate password-reset requests against a reset key or verify the requester's identity. Additionally, it issues authentication sessions based on unverified third-party sign-in data. This allows unauthenticated attackers to reset any user's password or log in as any existing user, including administrators, potentially leading to full site takeover.
