    ts-deepmerge: Prototype Method Override leads to DoS

    CVE-2026-12644 · GHSA-87mf-gv2c-c62c

    Affected
    • npm ts-deepmerge < 8.0.0
    Fixed in
    8.0.0· Vendor fix available
    Issue
    Versions of the package ts-deepmerge before 8.0.0 are vulnerable to Uncaught Exception due to the improper handling of built-in Object.prototype methods (such as toString, valueOf). When user-controlled input contains these keys with non-function values, the resulting merged object becomes broken — any string context operation throws a TypeError, crashing the application.

    Recommended action: Upgrade to 8.0.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
