{"id":"CVE-2026-1645","state":"PUBLISHED","title":"Hostel <= 1.1.8 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'custom_currency' Parameter and Localization file URL Setting","description":"The Hostel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_currency' parameter and the 'locale_url' setting in all versions up to, and including, 1.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access, 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":"2026-09-22T07:41:12.398Z","updatedAt":"2026-09-22T14:12:27.374Z","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":["prasunsen Hostel"],"affected":[{"vendor":"prasunsen","product":"Hostel","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/75693bd1-f022-47b9-b498-5ea1bda387e3?source=cve","https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/views/options.php#L17","https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/models/hostel.php#L266","https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/helpers/htmlhelper.php#L275","https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/helpers/htmlhelper.php#L278"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1645.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1645","state":"PUBLISHED","datePublished":"2026-09-22T07:41:12.398Z","dateUpdated":"2026-09-22T14:12:27.374Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-29T18:38:50.307Z"},"containers":{"cna":{"title":"Hostel <= 1.1.8 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'custom_currency' Parameter and Localization file URL Setting","descriptions":[{"lang":"en","value":"The Hostel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_currency' parameter and the 'locale_url' setting in all versions up to, and including, 1.1.8 due to insufficient input sanitization and output escaping.
