CVE-2025-32792Network attack vector

Host binding disclosure via nonopaque scope Proxy

Published Apr 18, 2025 · Updated Apr 21, 2025

Information disclosure in Endo SES before 1.12.0 allows remote attackers to read host lexical bindings through Compartment code. The Compartment scope Proxy exposes names absent from globalThis to the surrounding lexical scope instead of remaining fully opaque. Exposure requires a page or extension to evaluate attacker-controlled code after declaring top-level const, let, or class bindings, and disclosure is limited to those bindings.
