This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with author-level access and above, to send arbitrary newsletter emails to users of any WordPress role, including administrators, by forging POST fields during a normal post submission. This allows an attacker-supplied role slug via the newsletters_mailinglistsroles POST field to be passed directly to get_users(), enabling unauthorized mass-mailing and potential phishing against privileged site users through the site's own outbound email channel."}],"title":"Newsletters <= 4.17 - Missing Authorization to Authenticated (Author+) Arbitrary Modification via 'newsletters_mailinglistsroles' POST Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1d3eddce-1b41-4a33-8d57-bd594cf06a06?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/newsletters-lite/tags/4.17/wp-mailinglist.php#L3957"},{"url":"https://plugins.trac.wordpress.org/browser/newsletters-lite/tags/4.17/wp-mailinglist.php#L4114"},{"url":"https://plugins.trac.wordpress.org/browser/newsletters-lite/tags/4.17/wp-mailinglist.php#L3897"},{"url":"https://plugins.trac.wordpress.org/browser/newsletters-lite/tags/4.17/includes/checkinit.php#L63"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3663788%40newsletters-lite&new=3663788%40newsletters-lite"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"timeline":[{"time":"2026-08-18T15:14:28.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-24T22:25:17.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-25T18:03:24.746884Z","id":"CVE-2026-75908","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":"2026-08-25T18:03:51.392Z"}}]}}
