CVE-2026-75986: Online Job Portal System SQLi Vulnerability

CVE-2026-75986 Overview

CVE-2026-75986 is a SQL injection vulnerability in code-projects Online Job Portal System 1.0. The flaw resides in the password recovery component, specifically within the /ForPass.php file. Attackers can manipulate the txtUserName parameter to inject arbitrary SQL statements into the backend database query.

The vulnerability is remotely exploitable without authentication or user interaction. Public disclosure of the exploit technique has occurred, increasing the likelihood of opportunistic scanning and abuse. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can inject SQL through the txtUserName parameter in /ForPass.php, potentially exposing credentials and user records stored in the application database.

Affected Products

code-projects Online Job Portal System 1.0
/ForPass.php password recovery component
Deployments exposing the password recovery endpoint to untrusted networks

Technical Details for CVE-2026-75986

Vulnerability Analysis

The vulnerability affects the password recovery workflow of the Online Job Portal System. When a user submits a request to recover credentials, the application reads the txtUserName parameter and passes it into a backend SQL query without proper neutralization. This allows an attacker to break out of the intended query context and append arbitrary SQL clauses.

Because the endpoint is reachable pre-authentication, an attacker only needs network access to the web application. The EPSS probability is 0.328%, indicating early-stage exploitation likelihood consistent with a newly disclosed public flaw. Successful exploitation exposes stored credentials, user records, and other data that the application account can read.

Root Cause

The root cause is improper neutralization of user-supplied input in a downstream SQL component [CWE-74]. The ForPass.php handler concatenates or interpolates the txtUserName value into a SQL statement rather than using parameterized queries or prepared statements. Any special characters submitted by the client become part of the SQL grammar executed by the database.

Attack Vector

Exploitation is performed over the network by sending a crafted HTTP request to /ForPass.php with a malicious txtUserName value. The attacker supplies SQL metacharacters and payload fragments to alter query logic, extract data via UNION-based or boolean-based techniques, or enumerate schema through error-based responses. No credentials or user interaction are required.

Detection Methods for CVE-2026-75986

Indicators of Compromise

HTTP POST or GET requests to /ForPass.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the txtUserName parameter.
Web server or application logs showing repeated failed password recovery attempts with unusual username values or encoded payloads.
Database error messages returned in HTTP responses referencing SQL syntax near the txtUserName value.

Detection Strategies

Inspect access logs for /ForPass.php requests where the txtUserName parameter contains SQL keywords, comment sequences, or URL-encoded quotes.
Deploy web application firewall rules that flag SQL injection patterns targeting the password recovery endpoint.
Correlate spikes in /ForPass.php traffic with subsequent anomalous database read volume from the application service account.

Monitoring Recommendations

Enable verbose logging on the web tier and forward events to a centralized log platform for query-based hunting.
Alert on any HTTP 500 responses originating from ForPass.php, which often indicate broken SQL statements produced during injection attempts.
Monitor the application database user for unexpected SELECT volume against user credential tables.

How to Mitigate CVE-2026-75986

Immediate Actions Required

Restrict network access to the /ForPass.php endpoint until a code-level fix is applied, using firewall rules or reverse-proxy allowlists.
Rotate credentials and reset session tokens for any accounts that may have been exposed through the vulnerable query.
Audit the application database service account and reduce its permissions to the minimum required for password recovery.

Patch Information

No vendor patch is documented in the enriched data for CVE-2026-75986. Administrators should monitor the code-projects site and the VulDB Vulnerability #391905 entry for future advisories. Until a fix is issued, apply compensating controls at the network and application layers.

Workarounds

Rewrite the ForPass.php query to use parameterized statements or prepared statements with bound parameters for txtUserName.
Add server-side input validation that rejects non-alphanumeric characters in username fields before any database interaction.
Deploy a web application firewall signature that blocks SQL injection payloads targeting the txtUserName parameter on /ForPass.php.
