{"id":"CVE-2023-1259","state":"PUBLISHED","title":"Hotjar <= 1.0.15 - Authenticated (Administrator+) Stored Cross-Site Scripting","description":"The Hotjar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the hotjar_site_id in versions up to, and including, 1.0.15 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","publishedAt":"2023-10-14T11:09:10.321Z","updatedAt":"2026-04-08T17:11:25.715Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["hotjar Hotjar"],"affected":[{"vendor":"hotjar","product":"Hotjar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.15","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9c640bcb-b6bf-4865-b713-32ca846e4ed9?source=cve","https://plugins.trac.wordpress.org/browser/hotjar/tags/1.0.14/includes/class-hotjar.php#L40","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=2983524%40hotjar&new=2983524%40hotjar&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/1xxx/CVE-2023-1259.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-1259","state":"PUBLISHED","datePublished":"2023-10-14T11:09:10.321Z","dateUpdated":"2026-04-08T17:11:25.715Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2023-03-07T19:54:23.323Z"},"containers":{"cna":{"title":"Hotjar <= 1.0.15 - Authenticated (Administrator+) Stored Cross-Site Scripting","descriptions":[{"lang":"en","value":"The Hotjar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the hotjar_site_id in versions up to, and including, 1.0.15 due to insufficient input sanitization and output escaping.
