Organizations using the affected versions of Nuss are strongly advised to apply the vendor-supplied patch immediately. As a temporary mitigation, organizations can also use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block malicious serialized objects. However, these are not long-term solutions, and applying the patch should be the ultimate goal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The Common Vulnerabilities and Exposures (CVE) system has recently identified a critical vulnerability, CVE-2025-52827, within uxper Nuss.
