This is due to the function being hooked to `admin_init` without any `current_user_can()` check or nonce verification. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the site's Office 365 OAuth mail configuration (access token, refresh token, and user email) via a crafted URL. The configuration option is used during wizard setup of Microsoft365 SMTP, only available in the Pro option of the plugin. This could cause an Administrator to believe an attacker-controlled Azure app is their own, and lead them to connect the plugin to the attacker's account during configuration after upgrading to Pro.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Post SMTP \u003c= 3.8.0 - Missing Authorization to Authenticated (Subscriber+) Office 365 OAuth Configuration Overwrite","id":"CVE-2026-2559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"kalcaddle kodbox Media File Preview Plugin VideoResize.class.php run os command injection","id":"CVE-2026-2560"},"packages":[],"prev":{"headline":"GeekAI net_handler.go Download server-side request forgery","id":"CVE-2026-2558"},"products":["Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP \u0026 Mobile App"],"published":"2026-03-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["saadiqbal"]},"summary":"Authenticated subscribers can overwrite Office 365 OAuth settings due to missing capability checks, potentially hijacking email configuration.","url":"https://insights.sbomify.com/CVE-2026-2559/"}
