Deeper analysis
CVE-2026-4842 is a SQL injection vulnerability in itsourcecode Online Enrollment System 1.0, published on 2026-03-26. It affects unknown code in the file /sms/grades/index.php?view=edit&id=1 within the Parameter Handler component, where manipulation of the 'deptid' argument triggers the issue. The vulnerability is classified under CWE-74 and CWE-89.
The vulnerability carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), meaning it can be exploited remotely over the network with low attack complexity, requiring no privileges or user interaction. Remote attackers can manipulate the 'deptid' parameter to inject SQL, potentially achieving low-level impacts on confidentiality, integrity, and availability.
