Description

A flaw was found in spice-server. Multiple migration data handlers use client-supplied offsets from SPICE_MSGC_MIGRATE_DATA messages without bounds validation, allowing a malicious authenticated SPICE client during VM live migration to read arbitrary heap memory or trigger heap corruption via out-of-bounds read and write operations on the message buffer.

CVE-2026-97640

The WPConsent – Cookie Banner & Cookie Consent for Privacy Compliance (GDPR / CCPA / EU Compliance Cookie Notice) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Simple HTML DOM Parser Noise-Key Restoration (mXSS) in all versions up to, and including, 1.1.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Script Blocking feature to be enabled, and the exploit chain depends on an attacker submitting two coordinated comments — one embedding event-handler syntax inside an allowed element and one placing the deterministic ___noise___ restoration key inside an allowed attribute — with the key offset confirmable via an unauthenticated wpconsent_debug=1 request.
