Reflected XSS via sessionpriv.php URL
Published Apr 14, 2021 · Updated Aug 3, 2024
Cross-site scripting in the Jitsi Meet Moodle plugin 2.7 through 2.8.3 allows remote attackers to inject JavaScript through a crafted URL. The sessionpriv.php module incorporates attacker-controlled URL content into a page without adequate output encoding, so script executes when a user follows the link. Exploitation requires no prior authentication but does require a victim to click the malicious URL; the demonstrated impact is unauthorized script execution in the application context, with confidentiality and integrity exposure but no service interruption.
