Drupal Core Critical Vulnerability High Exploitation Risk | MSSP Advisory

Drupal released emergency security patches today for a critical vulnerability affecting Drupal 10.2 and 10.3 with exploitation risk so high that attackers may weaponize it within hours of disclosure. The bug impacts Drupal core functionality and carries a maximum 25/25 CVSS score for exploitability. Drupal explicitly warned that proof-of-concept exploits could appear immediately after technical details become public.

Your clients running Drupal sites face immediate compromise risk from a vulnerability that security researchers rate as highly exploitable within hours. Any MSSP managing web properties needs to patch every Drupal instance before threat actors reverse engineer the fix into working exploits. Client websites going offline from emergency patching beats explaining a breach tomorrow morning.
