7.2 highEPSS 71%

High (7.2) in strapi strapi. EPSS 71% chance of exploitation in the next 30 days. Fixed in @strapi/plugin-users-permissions 4.5.6.

Strapi through 4.5.5 allows authenticated Server-Side Template Injection (SSTI) that can be exploited to execute arbitrary code on the server. A remote attacker with access to the Strapi admin panel can inject a crafted payload that executes code on the server into an email template that bypasses the validation checks that should prevent code execution.
