{"cve":"CVE-2026-15948","nvd":{"published":"2026-08-15T04:18:08.773","modified":"2026-08-20T12:48:10.287","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["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/browser/hydra-booking/trunk/app/Content/Archive/archive-page-tfhb-host.php#L30","https://plugins.trac.wordpress.org/changeset?reponame=&old=3632543%40hydra-booking&new=3632543%40hydra-booking","https://www.wordfence.com/threat-intel/vulnerabilities/id/8331fe3f-e943-4f4c-887f-761f3e18eb79?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-15948","score":0.00361,"percentile":0.29902,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
