{"id":"CVE-2026-15948","state":"PUBLISHED","title":"Hydra Booking <= 1.2.2 - Authenticated (Host+) Stored Cross-Site Scripting via 'first_name' Parameter","description":"The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'first_name' parameter in all versions up to, and including, 1.2.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with host-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The tfhb_host role required to exploit this vulnerability can be self-assigned by any visitor via the plugin's public Signup shortcode, making this effectively exploitable by unauthenticated users who complete the registration flow.","publishedAt":"2026-08-15T03:25:58.930Z","updatedAt":"2026-08-17T16:07:11.999Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themefic Hydra Booking — Appointment Scheduling & Booking Calendar"],"affected":[{"vendor":"themefic","product":"Hydra Booking — Appointment Scheduling & Booking Calendar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8331fe3f-e943-4f4c-887f-761f3e18eb79?source=cve","https://plugins.trac.wordpress.org/browser/hydra-booking/trunk/app/Content/Archive/archive-page-tfhb-host.php#L30","https://plugins.trac.wordpress.org/browser/hydra-booking/trunk/admin/Controller/HostsController.php#L495","https://plugins.trac.wordpress.org/browser/hydra-booking/trunk/admin/Controller/HostsController.php#L77","https://plugins.trac.wordpress.org/changeset?reponame=&old=3632543%40hydra-booking&new=3632543%40hydra-booking"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15948.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15948","state":"PUBLISHED","datePublished":"2026-08-15T03:25:58.930Z","dateUpdated":"2026-08-17T16:07:11.999Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-16T13:01:32.821Z"},"containers":{"cna":{"title":"Hydra Booking <= 1.2.2 - Authenticated (Host+) Stored Cross-Site Scripting via 'first_name' Parameter","descriptions":[{"lang":"en","value":"The Hydra Booking — Appointment Scheduling & Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'first_name' parameter in all versions up to, and including, 1.2.2 due to insufficient input sanitization and output escaping.
