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"}]}}}
