{"id":"CVE-2023-0556","state":"PUBLISHED","title":"ContentStudio <= 1.2.5 - Missing Authorization","description":"The ContentStudio plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions in versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to obtain the blog metadata (via the function cstu_get_metadata) that includes the plugin's contentstudio_token. Knowing this token allows for other interactions with the plugin such as creating posts in versions prior to 1.2.5, which added other requirements to posting and updating.","publishedAt":"2023-01-27T21:08:16.313Z","updatedAt":"2026-04-08T16:52:55.776Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["contentstudio ContentStudio"],"affected":[{"vendor":"contentstudio","product":"ContentStudio","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/52db8d41-859a-4d68-8b83-3d3af8f1bf64?source=cve","https://plugins.trac.wordpress.org/browser/contentstudio/tags/1.2.1/contentstudio-plugin.php#L517","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=2851006%40contentstudio%2Ftrunk&old=2844028%40contentstudio%2Ftrunk&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/52db8d41-859a-4d68-8b83-3d3af8f1bf64"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/0xxx/CVE-2023-0556.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-0556","state":"PUBLISHED","datePublished":"2023-01-27T21:08:16.313Z","dateUpdated":"2026-04-08T16:52:55.776Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2023-01-27T21:02:03.555Z"},"containers":{"cna":{"title":"ContentStudio <= 1.2.5 - Missing Authorization","descriptions":[{"lang":"en","value":"The ContentStudio plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions in versions up to, and including, 1.2.5.
