This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, the second shortcode attribute (used as button text) is passed to the `$text` variable without sanitization at line 79 and then output directly into an HTML `value` attribute at line 91 without `esc_attr()` or any other escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}],"title":"Hostel <= 1.1.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'wphostel-book' Shortcode","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/30339c0d-6632-4073-b4d5-3bb4a5b8a58d?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/models/hostel.php#L195"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/trunk/controllers/shortcodes.php#L91"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/controllers/shortcodes.php#L91"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/trunk/controllers/shortcodes.php#L79"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/controllers/shortcodes.php#L79"},{"url":"https://plugins.trac.wordpress.org/browser/hostel/trunk/models/hostel.php#L195"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3480942%40hostel&new=3480942%40hostel"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-07-09T19:36:51.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-10T14:38:57.759016Z","id":"CVE-2026-3907","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-10T14:39:09.572Z"}}]}}
