**Vulnerability Summary for the Week of December 15, 2025**
The Cybersecurity and Infrastructure Security Agency (CISA) Vulnerability Bulletin provides a comprehensive summary of new vulnerabilities that have been recorded in the past week. This bulletin serves as a crucial resource for organizations to stay informed about potential security threats and take proactive measures to protect their systems.
It's essential to note that, in some cases, the vulnerabilities listed in this bulletin may not yet have assigned CVSS (Common Vulnerability Scoring System) scores. The Common Vulnerabilities and Exposures (CVE) vulnerability naming standard is used to organize these vulnerabilities according to severity, as determined by the CVSS standard.
The division of high, medium, and low severities corresponds to the following score ranges:
- High: CVSS scores ranging from 9.0-10.0
- Medium: CVSS scores ranging from 4.0-8.9
- Low: CVSS scores below 4.0
The information provided in this bulletin is compiled from various sources, including external open-source reports and CISA analysis. In some cases, additional information may be included, such as identifying details, values, definitions, and related links.
When available, patch information is also provided to facilitate timely mitigation of these vulnerabilities. It's essential for organizations to stay up-to-date with the latest security patches and updates to ensure their systems remain secure.
