When a researcher discovers a vulnerability, they typically follow a responsible disclosure process. This involves reporting the flaw to the vendor (in this case, PHPGurukul) and allowing them time to develop and release a patch before making the details public. This process explains why we see CVEs (Common Vulnerabilities and Exposures) like (a SQL Injection in an online shopping portal), CVE-2025-52074 (an XSS in a cart function), and CVE-2024-39090 (a CSRF leading to Stored XSS). Each of these represents a flaw that was reported, assigned an ID, and for which a fix was eventually released.
