CVE-2026-27013 is a high-severity vulnerability affecting fabricjs fabric.js. It was published on February 19, 2026 and has a CVSS 3.1 base score of 7.6 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.6, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Fabric.js is a Javascript HTML5 canvas library. Prior to version 7.2.0, Fabric.js applies `escapeXml()` to text content during SVG export (`src/shapes/Text/TextSVGExportMixin.ts:186`) but fails to apply it to other user-controlled string values that are interpolated into SVG attribute markup. When attacker-controlled JSON is loaded via `loadFromJSON()` and later exported via `toSVG()`, the unescaped values break out of XML attributes and inject arbitrary SVG elements including event handlers. Any application that accepts user-supplied JSON (via `loadFromJSON()`, collaborative sharing, import features, CMS plugins) and renders the `toSVG()` output in a browser context (SVG preview, export download rendered in-page, email template, embed) is vulnerable to stored XSS. An attacker can execute arbitrary JavaScript in the victim's browser session. Version 7.2.0 contains a fix.
Remediation
Check the references section for vendor advisories and patches from fabricjs. Update fabric.js to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
