This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The save_ams_license_key AJAX handler performs no capability check and no nonce verification, meaning any authenticated user with Subscriber-level access or above can invoke it to store the malicious payload."}],"title":"AppMySite <= 3.15.3 - Authenticated (Subscriber+) Stored Cross-Site Scripting via save_ams_license_key AJAX Handler","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/34c573f4-bc21-4a5f-a44a-779c523c3212?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/appmysite/tags/3.15.3/includes/views/ams-home.php#L125"},{"url":"https://plugins.trac.wordpress.org/browser/appmysite/tags/3.15.3/includes/class-ams-admin-functions.php#L67"},{"url":"https://plugins.trac.wordpress.org/browser/appmysite/tags/3.15.3/includes/class-ams-admin-functions.php#L34"},{"url":"https://plugins.trac.wordpress.org/browser/appmysite/tags/3.15.3/includes/views/ams-home.php#L222"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3635325%40appmysite&new=3635325%40appmysite"}],"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":"Mitchell"}],"timeline":[{"time":"2026-09-18T18:48:37.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-13770","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-19T13:24:12.263777Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-19T14:01:23.998Z"}}]}}
