As a temporary mitigation measure, users can also employ Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) to detect and prevent attempted exploits. However, these measures are not substitutes for applying the vendor-provided patch.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report provides an in-depth look at the critical vulnerability identified as CVE-2025-9365.
