Technical description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.13, an unauthenticated user who tricks another user into visiting a malicious web page could run unauthorized JavaScript in that user's browser. This could allow for unauthorized access to all relevant data available to that user and actions that affect system integrity. The Cross-Site Scripting (XSS) is possible because Splunk Web does not validate the origin and source of messages received by a page message handler. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will.

———lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.1, link attributes in ``lxml.html.defs.link_attrs`` were missing ``xlink:href``, which can be used for URL bypass attacks in embedded SVG/MathML/etc. content. This vulnerability was fixed in lxml 6.1.1 and lxml_html_clean 0.4.5.9h CVE-2026-64972—

———ATutor is vulnerable to Reflected XSS via popup parameter in preview.php. An authenticated attacker can inject a double quote into the popup parameter, break out of the attribute value, and append a new event handler such as onload. The related preview_top.php file sanitises these parameters, but that does not prevent XSS in the parent frameset rendered by preview.php itself. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h CVE-2026-64971—

———ATutor is vulnerable to Reflected XSS in restore functionality. An attacker can provide a specially crafted URL that, when opened, results in arbitrary JavaScript execution in the victim's browser. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h CVE-2026-64970—

———ATutor is vulnerable to Stored Cross Site Scripting in registration functionality. An attacker can register a new account and enter a JavaScript payload in the phone field during registration. When any authenticated user visits the attacker's public profile, the profile template echoes the phone value without output encoding and the browser executes the payload leading to the theft of user's session cookie. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h CVE-2026-77072—

———n8n before 1.123.69, 2.33.4, and 2.34.1 contains a stored cross-site scripting vulnerability in the Form node's completion page. The completion page applied its sandboxing Content-Security-Policy only when respondWith was not set to 'redirect', but responseText was always rendered as raw HTML. An authenticated member could set respondWith to 'redirect' via an expression while keeping responseText populated, causing the completion page to serve unsanitized HTML and script from the n8n origin. Any visitor who submitted the resulting public form would have that script execute same-origin with their session.9h CVE-2026-734026.5 MED
