CVE-2026-27013 is a stored Cross-Site Scripting (XSS) vulnerability in Fabric.js, a Javascript HTML5 canvas library, affecting versions prior to 7.2.0. It arises when user-controlled JSON is loaded and subsequently exported to SVG, allowing unescaped values to inject arbitrary SVG elements and event handlers. This can lead to arbitrary JavaScript execution in a victim's browser session. The vulnerability has a CVSS score of 6.1 (Medium), indicating a low attack complexity and requiring user interaction, but with a high potential for impact on confidentiality and integrity. The attack vector is network-based, and no authentication is required. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal.
