What is CVE-2026-67173?
CVE-2026-67173 is a medium-severity server-side request forgery vulnerability in pivotick, published on 28 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Pivotick did not validate the URL scheme of node imagePath values derived from graph data before assigning them to SVG image resources. An attacker able to supply crafted graph data could set an image path to a malicious URI.
When a victim rendered the affected graph, the browser could resolve the attacker-controlled URI and initiate an unintended request or invoke scheme-specific handling in the victim’s context. Depending on the URI, browser behaviour, and installed protocol handlers, exploitation could disclose limited client or network metadata, facilitate rendering-based tracking, or attempt to access local or internal resources.
Exploitation requires a victim to load or render graph data containing the malicious imagePath. The patch normalizes ASCII whitespace and control characters in URI schemes and restricts image paths to relative URLs or the http, https, data, and blob schemes.
