Harvard University's Development Office Hit by Data Breach Following Sophisticated Vishing Campaign

URGENT: CISA Orders 7-Day Patch for Actively Exploited FortiWeb Zero-Day

CRITICAL

Fortinet Discloses Critical FortiWeb Zero-Day (CVE-2025-58034) Under Active Attack; CISA Issues Emergency Directive

Update:

Fortinet has officially patched the actively exploited CVE-2025-58034 in FortiWeb WAF, affecting 7.x and 8.x versions. The vulnerability was initially 'stealth-patched' in routine updates before public disclosure. A critical development is the release of an exploit module for this flaw in the Metasploit framework. This significantly lowers the technical barrier for exploitation, making it accessible to a wider range of threat actors and dramatically increasing the likelihood of widespread attacks. Organizations are urged to apply patches immediately due to the heightened risk.
