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. The exploit requires no user interaction beyond page load, as setting auto_open and consent_enabled to 'yes' in the injected data-box JSON causes the consent box — and the embedded script — to execute immediately on page load."}],"title":"Social Chat <= 8.6.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'consent_message' JSON Attribute in .qlwapp data-box","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f159392b-5bc6-4c12-a924-13ea170bb7fa?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-whatsapp-chat/tags/8.6.1/build/frontend/js/index.js#L2"},{"url":"https://plugins.trac.wordpress.org/browser/wp-whatsapp-chat/tags/8.6.1/lib/controllers/class-frontend.php#L86"},{"url":"https://plugins.trac.wordpress.org/browser/wp-whatsapp-chat/tags/8.5.1/build/frontend/js/index.js#L2"},{"url":"https://plugins.trac.wordpress.org/browser/wp-whatsapp-chat/tags/8.5.1/lib/controllers/class-frontend.php#L86"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&new=3667778%40wp-whatsapp-chat%2Ftags%2F8.6.3&old=3664149%40wp-whatsapp-chat%2Ftags%2F8.6.2"},{"url":"https://plugins.trac.wordpress.org/changeset?old_path=%2Fwp-whatsapp-chat/tags/8.6.2&new_path=%2Fwp-whatsapp-chat/tags/8.6.3"}],"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":"suyoung kim(AhnLab)"}],"timeline":[{"time":"2026-09-04T17:07:05.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-18404","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-07T11:07:50.042940Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-07T11:17:26.202Z"}}]}}
