CVE-2026-82634: Frappe Framework Development Branch Incorrect Authorization via Jinja Template Preview Endpoint
Frappe Framework development builds contain an authorization flaw in the renderjinjatemplate endpoint that allows low-privileged users to render arbitrary Jinja templates by supplying raw template strings. Attackers with print permission on any document can execute arbitrary SELECT statements against unrelated tables, including reading password hashes from the Auth table.

Frequently Asked Questions
Who can exploit this issue?
A low-privileged authenticated user who has print permission on any document can exploit the affected endpoint. The user does not need permission to the unrelated data they query.
What access can an attacker gain through exploitation?
An attacker can supply arbitrary raw Jinja template strings and execute arbitrary SELECT statements against unrelated database tables. This includes reading password hashes from the __Auth table.
Are production Frappe Framework releases affected?
The available information identifies Frappe Framework development builds as affected. It does not state whether any specific production release is affected.
What is the relevant indicator of exposure?
Exposure depends on whether the deployment includes the vulnerable render_jinja_template behavior and users have print permission on documents. The provided information does not include logging indicators or a method to confirm prior exploitation.
