What is CVE-2026-66825?
CVE-2026-66825 is a medium-severity cross-site scripting vulnerability in pivotick, published on 27 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Pivotick contains a cross-site scripting vulnerability in the sidebar property-list component. Values associated with link-like properties, such as url, uri, href, link, website, or homepage, were rendered as hyperlinks without validating their URL scheme.
An attacker able to supply or influence node or edge property data could provide a malicious value using the javascript: scheme, including variants obfuscated with whitespace or control characters. If a user clicked the generated property link, attacker-controlled JavaScript could execute in the context of the Pivotick application.
Successful exploitation could allow the attacker to access information available to the victim’s browser session or perform actions with the victim’s privileges. The vulnerability was addressed by normalizing property values and preventing URLs with non-allowlisted schemes from being rendered as clickable links.
