Cybersecurity Briefing for November 21, 2022: Vulnerabilities and Threats Abound

Lead Story: CISA Highlights Critical Vulnerabilities

On November 21, 2022, the Cybersecurity and Infrastructure Security Agency (CISA) published a bulletin detailing several high-severity vulnerabilities that pose significant risks. Notably, the WPQA Builder WordPress plugin was flagged for lacking CSRF security checks, potentially allowing unauthorized actions on behalf of users. Additionally, multiple SQL injection vulnerabilities were identified in AeroCMS, which could lead to unauthorized access to sensitive data.
