Last modified

CVE-2026-8656 is a low-severity vulnerability rated 2/10 on the CVSS scale. 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.. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
