CVE-2026-10261 Overview
CVE-2026-10261 is a SQL injection vulnerability in CodeAstro Online Job Portal 1.0. The flaw resides in the /users/application_status.php script, where the ID parameter is passed directly into a database query without proper sanitization. Remote attackers can manipulate this argument to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed deployments. This issue is tracked 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 ID parameter in application_status.php, potentially exposing or modifying applicant data stored in the portal database.
Affected Products
- CodeAstro Online Job Portal 1.0
- Deployments exposing /users/application_status.php to untrusted networks
- Installations without input validation patches applied

Technical Details for CVE-2026-10261
Vulnerability Analysis
The vulnerability exists in the user-facing application status page at /users/application_status.php. The script accepts an ID argument over HTTP and incorporates it into a backend SQL query without parameterization or sanitization. An attacker can supply crafted input containing SQL metacharacters to alter query logic.
Because the endpoint requires no authentication and the attack travels over the network, exploitation can be automated. Successful injection can disclose database records, bypass logic that depends on query results, or modify stored data depending on database privileges granted to the web application user.
Root Cause
The root cause is improper neutralization of input used in a SQL statement [CWE-74]. The application concatenates the ID request parameter into a query string rather than using prepared statements with bound parameters. Any single quote, comment sequence, or UNION clause supplied by the attacker is interpreted by the database engine.
Attack Vector
The attack is remote and unauthenticated. An attacker issues an HTTP request to application_status.php with a malicious ID value, for example appending boolean conditions or UNION SELECT statements. The injected payload executes within the database context of the Job Portal application, allowing data extraction or tampering. A public proof of concept is referenced in the GitHub CVE Issue Discussion and the VulDB CVE-2026-10261 entry.
Detection Methods for CVE-2026-10261
Indicators of Compromise
- HTTP requests to /users/application_status.php containing SQL metacharacters such as ', --, ;, UNION, or SELECT in the ID parameter
- Unusual outbound database errors or stack traces returned in HTTP responses from the portal
- Spikes in request volume against application_status.php from a single source address
Detection Strategies
- Inspect web server access logs for suspicious ID values, including URL-encoded SQL syntax and time-based payloads such as SLEEP( or BENCHMARK(
- Deploy a Web Application Firewall (WAF) rule set tuned for SQL injection patterns targeting PHP applications
- Correlate database error events with corresponding HTTP requests to identify exploitation attempts
Monitoring Recommendations
- Monitor database audit logs for unexpected queries originating from the Job Portal service account
- Alert on HTTP 500 responses from application_status.php that coincide with parameter manipulation
- Track authentication anomalies on the database layer that may indicate data exfiltration following injection
How to Mitigate CVE-2026-10261
Immediate Actions Required
- Restrict external access to /users/application_status.php until a code-level fix is applied
- Place the application behind a WAF with SQL injection signatures enabled in blocking mode
- Rotate database credentials used by the Job Portal if log review shows evidence of exploitation
- Review applicant records for unauthorized modifications or disclosures
Patch Information
No official vendor patch has been published in the referenced advisories at the time of CVE assignment. Administrators should consult the CodeAstro Security Resource and the VulDB Vulnerability #367541 entry for vendor updates. Until a patch is released, custom code remediation is required: replace string concatenation in application_status.php with prepared statements using PDO or mysqli parameter binding, and cast the ID value to an integer before use.
Workarounds
- Enforce strict server-side input validation that limits the ID parameter to numeric values only
- Apply least-privilege database permissions so the web user cannot read sensitive tables or execute administrative statements
- Disable verbose SQL error messages in PHP configuration to reduce information leakage to attackers
# Configuration example: restrict ID parameter to digits via Apache mod_rewrite
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)ID=([^0-9&]|%27|%22|--) [NC]
RewriteRule ^users/application_status\.php$ - [F,L]
