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.","published_at":"2026-02-19T19:38:19.711000Z","last_modified_at":null,"cvss_v3_score":7.6,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:L","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79","CWE-116"],"nvd_references":["https://github.com/fabricjs/fabric.js/security/advisories/GHSA-hfvx-25r5-qc3w","https://github.com/fabricjs/fabric.js/commit/7e1a122defd8feefe4eb7eaf0c180d7b0aeb6fee","https://github.com/fabricjs/fabric.js/releases/tag/v720"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:30.261368Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"fabricjs","vendor_name":"fabricjs","product_slug":"fabric.js","product_name":"fabric.js","version_start":"< 7.2.0","version_start_inclusive":true,"version_end":"< 7.2.0","version_end_inclusive":true,"cpe23_uri":"cve5:fabricjs:fabric.js:< 7.2.0:< 7.2.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/fabricjs/fabric.js/security/advisories/GHSA-hfvx-25r5-qc3w","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/fabricjs/fabric.js/commit/7e1a122defd8feefe4eb7eaf0c180d7b0aeb6fee","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/fabricjs/fabric.js/releases/tag/v720","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-19T19:38:19.711000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:17.441167Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:17.441167Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:17.441167Z","label":"CVSS score revised","source":"cvelistv5"}]}
