Horilla: Server-Side Template Injection (SSTI) in Mail Preview Endpoints Allows Authenticated Users to Disclose Password Hashes and Server Metadata

Assigner: GitHub_M
Reserved: 16.07.2026 Published: 25.09.2026 Updated: 25.09.2026

Horilla is an HR and CRM software. From 1.0.0 until 1.6.0 and 2.0.0, the get_mail_preview handlers in recruitment/views/actions.py and employee/not_in_out_dashboard.py render a user-controlled body at /recruitment/get-mail-preview/ and /employee/get-employee-mail-preview with the full request object in the Django template context. An authenticated user with a valid CSRF token can use template attribute traversal to read request.user.password, request.META, and related-user attributes, exposing password hashes, personal data, and server request metadata. Django template restrictions prevent arbitrary code execution through this primitive, so the demonstrated impact is information disclosure and possible offline password cracking or account compromise. This issue is fixed in versions 1.6.0 and 2.0.0.
