Security readout for executives and security teams
Plain-English summary
CVE-2026-1422 is a SQL injection issue in the login page of code-projects Online Examination System 1.0. A remote attacker may manipulate the login “User” field to affect the database. Public proof-of-concept material is referenced, but the provided sources do not show confirmed active exploitation.
Executive priority
Treat as high priority if this examination system is in use or internet-facing. The issue targets authentication, has public exploit information, and could affect database confidentiality, integrity, and availability. If the product is not deployed, document non-exposure and monitor for inherited code reuse.
Technical view
The vulnerability affects /index.php in the Login Page component. Manipulation of the User argument can cause SQL injection. VulDB lists remote, unauthenticated exploitation with low attack complexity and CVSS 2.0 score 7.5. CWE mappings include CWE-89 and CWE-74. No vendor patch is identified in the provided sources.
Likely exposure
Exposure is most likely where code-projects Online Examination System 1.0 is deployed and the login page is reachable over a network, especially the internet. Organizations using derivative or copied source code should also review whether the same login logic exists.
Exploitation context
The source bundle states a public exploit exists and could be used. CISA KEV is false, and no cited source confirms active exploitation. Risk is elevated because the login page is typically exposed and the attack requires no authentication.
Researcher notes
Evidence comes primarily from VulDB, CVE records, and a public GitHub reference. The affected version is listed as 1.0. Patch status is not established in the supplied sources. Avoid assuming broader product versions or confirmed exploitation without additional vendor or telemetry evidence.
Mitigation direction
- Check code-projects and VulDB pages for any vendor guidance or updated release.
- Remove public internet exposure for the application if not required.
- Restrict access to the login page with network controls where feasible.
- Review and fix database queries handling the User field using parameterized queries.
- Monitor web and database logs for abnormal login-page database errors.
Validation and detection
- Inventory systems running code-projects Online Examination System 1.0.
- Confirm whether /index.php login is reachable from untrusted networks.
- Review login code for unsafe handling of the User parameter.
- Check logs for suspicious login attempts and SQL error patterns.
- Verify whether any local customizations already remediate SQL injection.
