SCA: security update for fabric (GHSA-hfvx-25r5-qc3w)
medium Tenable Cloud Security Plugin ID 437835
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2026-27013)
