CISA Adds One Known Exploited Vulnerability to Catalog

CISA Advisories [CISA KEV] | CVSS 9.8 | CVE-2026-87902

❓ Why Should I Care?
Yes, if you run WordPress Core versions 5.8.0 to 6.2.3: this vulnerability allows attackers to remotely execute files, potentially taking full control of your server.

🎯 Affected versions: 5.8.0 to 6.2.3
Not affected: 6.2.4 and later

🎭 In plain English:

🔧 Prerequisites:

• Running WordPress Core versions 5.8.0 to 6.2.3
• Publicly accessible web server

⏱ Urgency: High urgency due to active exploitation and the risk of full server compromise.
