Attackers who capture a validly-signed SAMLResponse can replay it to the ACS endpoint repeatedly within its assertion validity window to log in as the victim, including administrators, without detection since the duplicate message ID check never triggers.</description></item><item><title>CVE-2026-107759: WPO365 | MICROSOFT 365 GRAPH MAILER &lt;= 6.2 - Unauthenticated Stored Cross-Site Scripting via Email Subject via wp_mail</title><link>https://vulnfeed.org/cve/CVE-2026-107759/</link><guid isPermaLink="true">https://vulnfeed.org/cve/CVE-2026-107759/</guid><pubDate>Sat, 31 Oct 2026 08:16:48 +0000</pubDate><description>The WPO365 | MICROSOFT 365 GRAPH MAILER plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &apos;Subject (via wp_mail/PHPMailer, e.g. CF7 your-subject)&apos; parameter in all versions up to, and including, 6.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is stored without authentication via any mail-sending feature that forwards a submitter-controlled subject (e.g. a Contact Form 7 form) when the Graph Mailer is enabled but OAuth authorization has not been completed, a default state immediately after plugin activation.</description></item></channel></rss>
