CVE-2026-15598Network attack vector

Prototype pollution via unfiltered deep-set paths

Published Jul 13, 2026 · Updated Jul 13, 2026

Prototype pollution in AntV Layout 2.0.0 allows remote authenticated users to modify shared object properties via a crafted path. The exported setNestedValue helper splits the caller-supplied dot path and passes its segments to a deep-set operation without rejecting proto or constructor.prototype. Exploitation requires a downstream application to pass attacker-controlled path data; polluted properties can alter application logic or interrupt service.
