Analyst readout for executives and security teams
Plain-English summary
CVE-2026-9542 is a SQL injection issue in CodeAstro Leave Management System 1.0. A remote authenticated user may be able to manipulate the email_id field in /admin/add_staff.php and affect the database. Public proof-of-concept material is referenced, but the supplied sources do not show confirmed active exploitation.
Executive priority
Handle as a moderate-priority remediation item, higher if the application is internet-facing or used for HR data. Public exploit availability increases urgency, but the supplied evidence indicates authentication is required and does not confirm active exploitation.
Technical view
The vulnerability affects an unknown function in /admin/add_staff.php where the email_id argument can be manipulated for SQL injection. The record lists CWE-89 and CWE-74, CVSS v2 6.5, network access, low complexity, and authenticated access required. Scope is CodeAstro Leave Management System 1.0 only, based on supplied evidence.
Likely exposure
Exposure is likely limited to organizations running CodeAstro Leave Management System 1.0 with the admin staff-add route reachable. The CVSS vector indicates authenticated access is required. The bundle provides no internet-wide exposure data, hosted-service details, or evidence of other affected versions.
Exploitation context
The source bundle says exploit material is public and could be used for attacks. KEV is false, and no cited source in the bundle confirms active exploitation. Treat this as elevated watchlist risk because public proof-of-concept availability can accelerate opportunistic testing.
Researcher notes
Evidence is thin: the affected function is unnamed, remediation is not specified, and exploit details are referenced but should not be reproduced. Confirm authentication and role requirements locally. Do not generalize beyond CodeAstro Leave Management System 1.0 without additional vendor evidence.
Mitigation direction
- Check CodeAstro and VulDB guidance for any vendor patch or advisory.
- Restrict /admin access to trusted administrators and trusted networks.
- Review /admin/add_staff.php database handling around email_id.
- Use parameterized database queries if maintaining the application code.
- Monitor admin actions and database errors involving staff creation.
Validation and detection
- Inventory systems for CodeAstro Leave Management System 1.0.
- Confirm whether /admin/add_staff.php exists and is reachable.
- Verify whether admin routes require authentication and least privilege.
- Review logs for unusual staff-creation attempts or database errors.
- Track CVE, VulDB, and vendor pages for updates.
