{"id":"CVE-2026-14482","state":"PUBLISHED","title":"多说社会化评论框 <= 1.2 - Unauthenticated Privilege Escalation via api.php 'option'/'value' Parameters","description":"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.","publishedAt":"2026-07-08T04:30:50.223Z","updatedAt":"2026-07-08T13:57:46.333Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["shen2 多说社会化评论框"],"affected":[{"vendor":"shen2","product":"多说社会化评论框","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/732c7ccd-de50-4e27-8cb9-3bb0ed30f0b4?source=cve","https://plugins.trac.wordpress.org/browser/duoshuo/tags/1.2/LocalServer.php#L49","https://plugins.trac.wordpress.org/browser/duoshuo/tags/1.2/LocalServer.php#L54","https://plugins.trac.wordpress.org/browser/duoshuo/tags/1.2/api.php#L40"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14482.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14482","state":"PUBLISHED","datePublished":"2026-07-08T04:30:50.223Z","dateUpdated":"2026-07-08T13:57:46.333Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-02T16:25:33.538Z"},"containers":{"cna":{"title":"多说社会化评论框 <= 1.2 - Unauthenticated Privilege Escalation via api.php 'option'/'value' Parameters","descriptions":[{"lang":"en","value":"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.
