Privilege Escalation in 多说社会化评论框 (WordPress plugin) (CVE-2026-14482)
Summary
Vulnerability in 多说社会化评论框 (WordPress plugin) (CVE-2026-14482). Successful exploitation can lead to full system takeover. Exploitable via update_option.
Original description
The description as published by the source.
The 多说社会化评论框 plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2. The vulnerability exists due to a missing capability and nonce check on a directly web-accessible API endpoint, combined with a trivially forgeable HMAC-SHA1 signature keyed on an always-empty WordPress option, which allows the endpoint's update_option handler to pass attacker-controlled option and value parameters directly to WordPress's update_option function without any allowlist or sanitization. This makes it possible for unauthenticated attackers to update arbitrary WordPress options — such as setting default_role to administrator and enabling open registration — and subsequently register an account with full administrator privileges.
