{"id":"CVE-2026-8884","state":"PUBLISHED","title":"Instant-Quote.co Quotation Page <= 1.3.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The Instant-Quote.co Quotation Page plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output 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. A Contributor-level user can trigger execution against higher-privileged users by embedding the malicious shortcode in a post submitted for review, causing the injected scripts to execute when an administrator previews or views the post.","publishedAt":"2026-05-27T05:31:34.514Z","updatedAt":"2026-05-27T10:30:49.935Z","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":["neilmccutcheon Instant-Quote.co Quotation Page"],"affected":[{"vendor":"neilmccutcheon","product":"Instant-Quote.co Quotation Page","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.3.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f7140053-a3c3-44c4-bc83-2e9b9e8853d6?source=cve","https://plugins.trac.wordpress.org/browser/iq-quotation-page/trunk/IQ-quotation-page.php#L429","https://plugins.trac.wordpress.org/browser/iq-quotation-page/trunk/IQ-quotation-page.php#L339"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8884.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8884","state":"PUBLISHED","datePublished":"2026-05-27T05:31:34.514Z","dateUpdated":"2026-05-27T10:30:49.935Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-18T20:34:29.934Z"},"containers":{"cna":{"title":"Instant-Quote.co Quotation Page <= 1.3.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The Instant-Quote.co Quotation Page plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Shortcode Attributes in all versions up to, and including, 1.3.4 due to insufficient input sanitization and output escaping.
