Security readout for executives and security teams
This is a cross-site scripting issue in older HHVM versions. If an application serializes attacker-controlled strings with WDDX and exposes the output to users, malicious script or HTML could be injected into a browser context. Exposure is most likely in legacy HHVM deployments before 3.5.0 that use WDDX serialization on untrusted input. MediaWiki references provide disclosure context, but the supplied affected-product data is incomplete. Treat this as a legacy-platform cleanup item unless HHVM before 3.5.0 is still internet-facing or used by high-value applications. Active exploitation is not established in the supplied sources. Mitigation focus: Upgrade HHVM to 3.5.0 or later where feasible.; Check upstream HHVM and application vendor guidance for supported fixes.; Audit use of wddx_serialize_value with untrusted strings..
