CVE-2026-7028 Overview
A SQL Injection vulnerability has been discovered in CodeAstro Online Job Portal 1.0. The vulnerability exists in an unknown function within the file /admin/jobs-admins/delete-jobs.php of the All Jobs Page component. Manipulation of the ID argument enables SQL injection attacks, allowing remote attackers to execute arbitrary SQL queries against the backend database. The exploit has been publicly disclosed and may be actively used in attacks.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, data modification, or deletion of job listings in the portal's administrative interface.
Affected Products
- CodeAstro Online Job Portal 1.0
- /admin/jobs-admins/delete-jobs.php endpoint
- All Jobs Page component

Technical Details for CVE-2026-7028
Vulnerability Analysis
This vulnerability is classified as CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws including SQL injection. The vulnerable endpoint /admin/jobs-admins/delete-jobs.php fails to properly sanitize user-supplied input in the ID parameter before incorporating it into SQL queries.
The attack can be conducted remotely over the network and requires high-level privileges (administrative access) to exploit. While the vulnerability requires administrative credentials, successful exploitation could allow an authenticated attacker to extend their access beyond intended boundaries, extract sensitive data, or corrupt the database.
Root Cause
The root cause of this vulnerability stems from insufficient input validation and lack of parameterized queries in the delete-jobs.php file. When processing the ID parameter from user requests, the application directly concatenates this untrusted input into SQL statements without proper sanitization or the use of prepared statements. This allows attackers to inject malicious SQL syntax that alters the intended query logic.
Attack Vector
The attack is network-accessible and targets the administrative panel of the Online Job Portal. An attacker with administrative credentials can manipulate the ID parameter in requests to /admin/jobs-admins/delete-jobs.php to inject arbitrary SQL commands. Since this is an administrative function related to deleting jobs, the injection point could be exploited to:
- Extract sensitive information from the database through UNION-based or error-based injection techniques
- Modify or delete arbitrary database records beyond the intended job listing
- Potentially escalate privileges or access other database tables containing user credentials

Detection Methods for CVE-2026-7028
Indicators of Compromise
- Unusual SQL error messages in application logs related to /admin/jobs-admins/delete-jobs.php
- Unexpected database query patterns or bulk deletions in job listings
- HTTP requests to the affected endpoint containing SQL syntax characters such as single quotes, semicolons, or SQL keywords (UNION, SELECT, DROP)
- Anomalous access patterns to administrative job management functions
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the ID parameter
- Monitor application logs for SQL syntax errors originating from the delete-jobs.php endpoint
- Deploy database activity monitoring to identify unauthorized or anomalous queries
- Configure intrusion detection systems to alert on common SQL injection payload signatures targeting administrative endpoints
Monitoring Recommendations
- Enable detailed logging for all administrative actions in the Online Job Portal
- Set up real-time alerts for multiple failed or malformed requests to /admin/jobs-admins/delete-jobs.php
- Monitor database audit logs for unexpected DELETE, SELECT, or data exfiltration operations
- Review access logs for administrative accounts showing unusual activity patterns
How to Mitigate CVE-2026-7028
Immediate Actions Required
- Restrict access to the administrative panel to trusted IP addresses only until a patch is available
- Implement additional authentication controls for sensitive administrative functions
- Deploy a Web Application Firewall with SQL injection protection rules enabled
- Review and audit administrative account access and activity logs
Patch Information
As of the last modification date (2026-04-29), no official patch has been released by CodeAstro for this vulnerability. Users should monitor the CodeAstro Homepage for security updates. For additional vulnerability details and potential community patches, refer to VulDB Submission #797969.
Workarounds
- Implement input validation on the ID parameter to accept only numeric values
- Modify the delete-jobs.php file to use prepared statements with parameterized queries instead of direct string concatenation
- Restrict network access to the administrative interface using firewall rules or VPN requirements
- Consider disabling the delete functionality temporarily until proper input sanitization can be implemented
The vulnerability should be addressed by updating the affected code to use parameterized queries. An example mitigation approach for PHP would involve using PDO prepared statements:
# Recommended mitigation: Use prepared statements
# Replace direct query concatenation with parameterized queries
# Example: $stmt = $pdo->prepare("DELETE FROM jobs WHERE id = ?");
# $stmt->execute([$id]);
