CVE-2026-75014 Overview
CVE-2026-75014 is a SQL injection vulnerability in SourceCodester Pet Grooming Management Software 1.0. The flaw resides in /admin/get_barcode_data.php, where the barcode parameter is passed to a database query without proper sanitization. An unauthenticated remote attacker can manipulate the parameter to inject arbitrary SQL statements. Public exploit details have been disclosed through VulDB and a GitHub issue tracker, increasing the likelihood of opportunistic scanning. The weakness is categorized under [CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component (Injection)].
Critical Impact
Remote, unauthenticated attackers can inject SQL through the barcode argument to read, modify, or destroy data managed by the pet grooming application.
Affected Products
- SourceCodester Pet Grooming Management Software 1.0
- Vulnerable endpoint: /admin/get_barcode_data.php
- Vulnerable parameter: barcode

Technical Details for CVE-2026-75014
Vulnerability Analysis
The vulnerability exists in the administrative barcode lookup handler /admin/get_barcode_data.php. The script accepts a user-supplied barcode argument and concatenates it directly into a SQL statement executed against the backend database. Because the argument bypasses parameterization and input sanitization, attacker-controlled content is interpreted as SQL syntax.
An attacker sends a crafted HTTP request containing SQL metacharacters or UNION-based payloads in the barcode value. The database returns rows influenced by the injected clause, enabling data exfiltration or logic manipulation. The endpoint is reachable over the network and does not require authentication or user interaction according to the published attack description.
Successful exploitation impacts the confidentiality, integrity, and availability of the underlying database. Attackers can enumerate schema, dump credentials stored in admin tables, or alter grooming appointment records.
Root Cause
The root cause is improper neutralization of special elements within a downstream SQL query [CWE-74]. The PHP handler builds the query string through direct concatenation of the barcode value rather than using prepared statements or parameter binding. No allow-list validation or type enforcement is applied before the value reaches the database driver.
Attack Vector
The attack vector is network-based. An attacker issues an HTTP GET or POST request to /admin/get_barcode_data.php supplying a malicious barcode parameter. Because the exploit has been published, adversaries can copy proof-of-concept payloads directly from the GitHub CVE Issue Tracker and VulDB Vulnerability Report.
The vulnerability is described in prose only; see the referenced advisories for payload specifics. Exploitation typically involves boolean-based, error-based, or UNION-based SQL injection techniques against the barcode argument.
Detection Methods for CVE-2026-75014
Indicators of Compromise
- HTTP requests to /admin/get_barcode_data.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the barcode parameter.
- Web server access logs showing anomalously long barcode values or URL-encoded SQL keywords.
- Database error messages surfaced in HTTP responses referencing MySQL syntax or table names.
- Unexpected outbound queries from the application database user or spikes in query volume against grooming tables.
Detection Strategies
- Deploy web application firewall (WAF) signatures that match SQL injection patterns targeting the barcode query parameter.
- Enable database query logging and alert on queries generated from /admin/get_barcode_data.php that include UNION or comment sequences.
- Correlate web access logs with authentication events to identify unauthenticated access to the /admin/ path.
Monitoring Recommendations
- Monitor for repeated 500-level HTTP responses from get_barcode_data.php, which often indicate injection probing.
- Track outbound traffic from the web server for unexpected data volumes that may signal database exfiltration.
- Baseline normal barcode values and alert on deviations in length, character class, or encoding.
How to Mitigate CVE-2026-75014
Immediate Actions Required
- Restrict access to /admin/get_barcode_data.php through network ACLs or authentication middleware until a fix is available.
- Deploy WAF rules that block SQL injection payloads on the barcode parameter.
- Audit the database user account used by the application and reduce its privileges to the minimum required.
- Review recent access logs and database audit trails for evidence of prior exploitation.
Patch Information
No vendor patch has been published at the time of writing. SourceCodester distributes source code through the SourceCodester Security Resources portal. Administrators should track the VulDB CVE Details CVE-2026-75014 entry for advisory updates and apply fixes as they become available.
Workarounds
- Rewrite the affected query in /admin/get_barcode_data.php to use prepared statements with bound parameters (PDO::prepare or mysqli_prepare).
- Enforce server-side input validation restricting the barcode parameter to expected alphanumeric character sets and length.
- Place the administrative interface behind a VPN or IP allow-list to remove unauthenticated network exposure.
- Consider replacing the application with a maintained alternative if the vendor does not publish a fix.
