Jorani vulnerabilities

Jorani before 1.0.4 contains a missing authorization vulnerability in Contracts::import() that allows any authenticated user to import days off into any contract from an arbitrary URL. Attackers can submit a contract id and URL via POST to overwrite non-working-day calendars and abuse get_headers() and fopen() for server-side request forgery against internal hosts.

Jorani before 1.0.4 contains a missing authorization vulnerability in the Hr controller's exportLeaves, exportOvertime and exportEmployees actions, allowing any authenticated user to export HR data. Attackers can request hr/exportEmployees or hr/exportLeaves/{id} and hr/exportOvertime/{id} to download employee names, emails, contracts, managers, and any employee's leave and overtime records.

Jorani before 1.0.4 contains an insecure direct object reference vulnerability that allows authenticated users to modify, delete, and view other employees' requests by authorizing by operation name only. Attackers can supply numeric request ids to Leaves::edit(), Extra::edit(), Leaves::delete(), Extra::delete(), and Leaves::history() to tamper with colleagues' leave and overtime requests and read leave history.

Jorani 1.0.3 contains a reflected cross-site scripting vulnerability in the language parameter that allows attackers to inject malicious scripts. Attackers can craft XSS payloads in the language parameter to execute arbitrary JavaScript and potentially steal user session information.
