Listen to this Post
The vulnerability is a stored Cross-Site Scripting (XSS) flaw within the Frappe LMS Job Form. In versions prior to 2.42.0, the application does not properly sanitize or validate user input in the “Company Website” field. An attacker with authenticated access to the system can submit a job posting containing malicious JavaScript code within this website field. This injected payload is then stored persistently in the application’s database. When a victim, such as another user or administrator, later views the malicious job posting listing, the stored script is served as part of the webpage and executes automatically in the victim’s browser. This execution occurs within the security context of the Frappe LMS site, allowing the attacker’s code to perform actions on behalf of the victim. Successful exploitation can lead to session hijacking, theft of authentication credentials, or unauthorized actions being performed within the victim’s account without their consent.
