    jsondiffpatch patch APIs are vulnerable to prototype pollution

    CVE-2026-8657 · GHSA-j4fx-xxwh-2485

    Affected
    • npm jsondiffpatch < 0.7.6
    Fixed in
    0.7.6· Vendor fix available
    Issue
    Versions of the package jsondiffpatch before 0.7.6 are vulnerable to Prototype Pollution via the jsondiffpatch.patch() and jsondiffpatch/formatters/jsonpatch.patch() APIs. An attacker can perform prototype pollution by supplying crafted delta or JSON Patch documents, as attacker-controlled property names and path segments are used to traverse and modify objects without restricting access to special properties like proto or constructor.prototype, allowing modification of Object.prototype.

    Recommended action: Upgrade to 0.7.6 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
