CVE-2026-8656 Details
Description
Versions of the package jsondiffpatch before 0.7.6 are vulnerable to Cross-site Scripting (XSS) via the annotated formatter due to improper sanitization of JSON values and property names. If an application compares untrusted JSON/object data and renders annotated formatter output in the DOM, attacker-controlled HTML can be interpreted by the browser, resulting in XSS.
A cross-site scripting (XSS) vulnerability has been identified in the jsondiffpatch package, specifically in versions prior to 0.7.6. The issue arises in the annotated formatter, where improper sanitization of JSON values and property names allows for the injection of attacker-controlled HTML. When applications compare untrusted JSON data and render the annotated formatter output in the DOM, this can be exploited to execute malicious scripts in the user's browser.
Users are advised to upgrade jsondiffpatch to version 0.7.6 or higher.
