This is due to insufficient input sanitization in the save_send_notification_flag() function and missing output escaping in the wpp_notification_box() function, which concatenates raw post meta values directly into HTML attribute and textarea contexts. 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":"Web Push Notifications <= 4.39.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'webpushr_notification_title' Post Meta Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/39286096-2efa-450b-b491-b3d40de5a4ae?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/webpushr-web-push-notifications/trunk/include/webpushr_functions.php#L513"},{"url":"https://plugins.trac.wordpress.org/browser/webpushr-web-push-notifications/trunk/include/webpushr_functions.php#L517"},{"url":"https://plugins.trac.wordpress.org/browser/webpushr-web-push-notifications/trunk/include/webpushr_functions.php#L699"},{"url":"https://plugins.trac.wordpress.org/browser/webpushr-web-push-notifications/trunk/include/webpushr_functions.php#L702"}],"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":"2026-07-22T18:44:42.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-23T16:04:44.460075Z","id":"CVE-2026-9729","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-23T16:04:51.114Z"}}]}}
