{"cve":"CVE-2026-4078","nvd":{"published":"2026-04-24T08:16:30.373","modified":"2026-06-17T10:55:57.283","status":"Deferred","description":"The ITERAS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple shortcodes (iteras-ordering, iteras-signup, iteras-paywall-login, iteras-selfservice) in all versions up to and including 1.8.2. This is due to insufficient input sanitization and output escaping in the combine_attributes() function. The function directly concatenates shortcode attribute values into JavaScript code within <script> tags using double-quoted string interpolation (line 489: '\"'.$key.'\": \"'.$value.'\"') without any escaping. An attacker can break out of the JavaScript string context by including a double-quote character in a shortcode attribute value and inject arbitrary JavaScript. 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.","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/iteras/tags/1.8.2/public/iteras-public.php#L489","https://plugins.trac.wordpress.org/browser/iteras/tags/1.8.2/public/iteras-public.php#L511","https://plugins.trac.wordpress.org/browser/iteras/tags/1.8.2/public/iteras-public.php#L519","https://plugins.trac.wordpress.org/browser/iteras/tags/1.8.2/public/iteras-public.php#L527","https://plugins.trac.wordpress.org/browser/iteras/tags/1.8.2/public/iteras-public.php#L551"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-4078","score":0.00257,"percentile":0.17411,"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).
