CVE-2026-15676 Overview
CVE-2026-15676 is a SQL injection vulnerability in code-projects Online Job Portal versions up to 1.0. The flaw resides in an unspecified function within the /Admin/DeleteUser.php file. An unauthenticated remote attacker can manipulate input parameters to inject arbitrary SQL statements into the underlying database query. Public exploit details have been released, increasing the likelihood of opportunistic attacks against exposed installations. The weakness is categorized under [CWE-74] for improper neutralization of special elements in output used by a downstream component.
Critical Impact
Remote, unauthenticated attackers can inject SQL queries through /Admin/DeleteUser.php to read, modify, or delete database records in Online Job Portal deployments.
Affected Products
- code-projects Online Job Portal versions up to and including 1.0
- Administrative component /Admin/DeleteUser.php
- Deployments exposing the admin interface to untrusted networks
Discovery Timeline
- 2026-07-14 - CVE-2026-15676 published to the National Vulnerability Database

Technical Details for CVE-2026-15676
Vulnerability Analysis
The vulnerability affects the administrative user deletion workflow in code-projects Online Job Portal. When an HTTP request reaches /Admin/DeleteUser.php, one or more request parameters flow directly into a SQL statement without proper sanitization or parameterization. This allows an attacker to alter query semantics by injecting SQL syntax through the vulnerable parameter.
Exploitation requires only network access to the admin endpoint. The public availability of exploit information means threat actors can weaponize the flaw with minimal effort. Successful injection can expose stored credentials, personal applicant data, and job postings maintained by the portal.
Root Cause
The root cause is failure to neutralize special SQL characters in user-controllable input before concatenating that input into a database query. The vulnerable code path in /Admin/DeleteUser.php does not use prepared statements or parameter binding, permitting query manipulation through crafted input values.
Attack Vector
The attack vector is network based and does not require authentication or user interaction. An attacker sends a crafted HTTP request to /Admin/DeleteUser.php containing SQL metacharacters or query fragments in the targeted parameter. The manipulated input alters the executed SQL, enabling data extraction, modification, or deletion depending on the underlying database privileges. Public exploit documentation is referenced through VulDB CVE-2026-15676 and the GitHub issue MY-CVE #4.
Detection Methods for CVE-2026-15676
Indicators of Compromise
- HTTP requests to /Admin/DeleteUser.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or %27
- Unexpected 500-series responses or database error messages returned from the DeleteUser endpoint
- Sudden mass deletion or modification of user records in the Online Job Portal database
Detection Strategies
- Deploy web application firewall rules that flag SQL injection patterns targeting /Admin/*.php paths
- Review web server access logs for repeated requests to /Admin/DeleteUser.php from a single source with anomalous query strings
- Enable database query auditing to capture unusual DELETE, UNION, or information_schema queries originating from the portal application
Monitoring Recommendations
- Alert on unauthenticated access attempts to any file under the /Admin/ directory
- Monitor outbound database connections for volumes inconsistent with normal admin activity
- Track file integrity of PHP files within the portal installation to catch webshell drops following exploitation
How to Mitigate CVE-2026-15676
Immediate Actions Required
- Restrict network access to the /Admin/ directory using IP allowlists or VPN-only reachability
- Place the Online Job Portal behind a web application firewall with SQL injection signatures enabled
- Rotate database credentials and administrative account passwords if compromise is suspected
- Audit the users, applications, and postings tables for unauthorized changes
Patch Information
No official vendor patch has been published in the referenced advisories at the time of NVD publication. Consult the Code Projects Resource Hub and the VulDB entry for CVE-2026-15676 for future updates. Organizations should consider replacing the affected component or applying source-level fixes that convert vulnerable queries to parameterized statements.
Workarounds
- Modify /Admin/DeleteUser.php to use prepared statements with bound parameters instead of string concatenation
- Enforce strict server-side input validation for numeric identifiers such as user IDs
- Disable or remove the vulnerable endpoint if the delete-user function is not required for operations
- Apply least-privilege database accounts so the web application cannot execute destructive statements beyond its scope
