CVE-2026-57527 (GCVE-0-2026-57527)
Vulnerability from nvd – Published: 2026-06-26 14:43 – Updated: 2026-06-26 16:31 X_Open Source

Title
ZAP ViewState Add-on Insecure Deserialization via JSFViewState.decode()
Summary
Zed Attack Proxy (ZAP) ViewState add-on before version 4 contains an insecure deserialization vulnerability that allows attackers who control a proxied web server to achieve arbitrary code execution by embedding a malicious serialized Java object in the javax.faces.ViewState HTTP response parameter. The JSFViewState.decode() method base64-decodes the ViewState value and passes it directly to ObjectInputStream.readObject() without a deserialization filter, allowlist, or type restriction, causing the malicious object to be deserialized within the ZAP JVM when the Desktop UI renders the ViewState panel.
