CVE-2026-63432 · Severity: medium · CVSS 6.5 · Published 2026-09-25

Horilla is an HR and CRM software that processes employee recruitment and data. Authenticated users can exploit template rendering vulnerabilities in the mail preview endpoints to read sensitive server data including password hashes, user information, and server metadata through template attribute traversal attacks. While this does not allow code execution, attackers could use exposed password hashes for offline cracking or account compromise.

## Technical details

The get_mail_preview handlers in recruitment/views/actions.py and employee/not_in_out_dashboard.py render user-controlled mail body content in Django templates with the full request object in context, allowing authenticated users with valid CSRF tokens to perform template attribute traversal to access request.user.password, request.META, and related user attributes. Django template restrictions prevent arbitrary code execution through this primitive. The vulnerability affects versions 1.0.0 through 1.6.0 and 2.0.0, and is fixed in versions 1.6.0 and 2.0.0.
