Cross-site scripting (XSS) vulnerability in blocks/html/block_html.php in Snoopy 1.2.3, as used in Moodle 1.6 before 1.6.9, 1.7 before 1.7.7, 1.8 before 1.8.8, and 1.9 before 1.9.4, allows remote attackers to inject arbitrary web script or HTML via an HTML block, which is not properly handled when the "Login as" feature is used to visit a MyMoodle or Blog page.

Security readout for executives and security teams

This is a legacy Moodle cross-site scripting issue. In affected 1.6, 1.7, 1.8, and 1.9 releases, an HTML block could inject script or HTML when a privileged user used Moodle's "Login as" feature and visited MyMoodle or Blog pages. Exposure is mainly organizations still running very old Moodle 1.6 before 1.6.9, 1.7 before 1.7.7, 1.8 before 1.8.8, or 1.9 before 1.9.4. Modern Moodle deployments are not shown as affected in the provided sources. Treat this as a legacy-platform risk. It is not supported by evidence of active exploitation in the provided sources, but any internet-accessible Moodle 1.x instance should be upgraded or retired because the vulnerable versions are very old. Mitigation focus: Upgrade affected Moodle branches to the fixed versions named in the advisory data.; Review Moodle vendor security guidance for any branch-specific remediation details.; Restrict administrative impersonation features where business operations allow..
