CVE-2025-66436: An SSTI (Server-Side Template Injection) vulnerability exists in the get_terms_and_conditions method of Frappe ERPNext through 15.89.0.

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

An SSTI (Server-Side Template Injection) vulnerability exists in the get_terms_and_conditions method of Frappe ERPNext through 15.89.0. The function renders attacker-controlled Jinja2 templates (terms) using frappe.render_template() with a user-supplied context (doc). Although Frappe uses a custom SandboxedEnvironment, several dangerous globals such as frappe.db.sql are still available in the execution context via get_safe_globals(). An authenticated attacker with access to create or modify a Terms and Conditions document can inject arbitrary Jinja expressions into the terms field, resulting in server-side code execution within a restricted but still unsafe context. This vulnerability can be used to leak database information.
