The \u591a\u8bf4\u793e\u4f1a\u5316\u8bc4\u8bba\u6846 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 \u2014 such as setting `default_role` to `administrator` and enabling open registration \u2014 and subsequently register an account with full administrator privileges.<\/p>\n","protected":false},"excerpt":{"rendered":"
