CVE-2026-14648: SQL Injection in code-projects Online Voting System — Critical Authentication Bypass

Technical summary

CVE-2026-14648 is a SQL injection vulnerability in the test_input function of /authentication.php in code-projects Online Voting System. The vulnerability stems from improper input validation of the adminUserName and adminPassword parameters during the login process (CWE-74: Improper Neutralization of Special Elements in Data Query Logic, CWE-89: SQL Injection). The lack of parameterized queries or input sanitization allows attackers to inject arbitrary SQL commands. The attack vector is network-based, requires no authentication prerequisites, and does not depend on user interaction. The CVSS v3.1 score of 7.3 (HIGH) reflects the combination of remote exploitability, low attack complexity, and partial impact across confidentiality, integrity, and availability.

Business impact

Organizations relying on code-projects Online Voting System for elections, surveys, or administrative voting processes face exposure of voter records, election data tampering, and potential system compromise. Attackers can extract sensitive information such as administrator credentials, voter details, and voting records. In regulated environments, such breaches trigger mandatory incident notification, reputational damage, and compliance violations. The public availability of exploit code accelerates the timeline to widespread attacks.

Affected systems

code-projects Online Voting System versions 0.x through 1.0 are affected. Verify your exact version against the vendor's release notes. Organizations should inventory all instances of this software, including test, staging, and production deployments, to determine exposure.

Exploitability

The vulnerability is highly exploitable. It requires only network access and no valid credentials to trigger; an attacker can target the login page directly. Proof-of-concept code has been publicly disclosed, lowering the barrier to exploitation. Automated scanning and mass exploitation are probable within days of public disclosure.

Remediation

Immediately upgrade to a patched version released by code-projects after 2026-07-06 (the modification date). If a patch is unavailable, isolate affected systems from the internet or implement a Web Application Firewall (WAF) rule to reject requests containing SQL metacharacters in the adminUserName and adminPassword fields. Apply input validation and parameterized queries to the authentication module as a compensating control. Perform a forensic audit to detect unauthorized access and database modifications.

Patch guidance

Check the code-projects project repository or vendor advisory for versions released after 2026-07-06. Patched versions should implement prepared statements or parameterized queries for all database interactions in the authentication component. Before deploying patches, test thoroughly in a non-production environment. Document all changes and retain backups for rollback purposes. After patching, change all administrator credentials to invalidate any compromised accounts.

Detection guidance

Monitor authentication logs for failed login attempts with unusual adminUserName or adminPassword values containing SQL keywords such as UNION, SELECT, OR, DROP, or comment sequences (-- or /*). Detect HTTP requests to /authentication.php with encoded or obfuscated payloads. Review web application firewall and intrusion detection system alerts for SQL injection patterns. Query your database audit logs for unexpected schema changes, privilege escalations, or data exfiltration post-2026-07-04. Consider deploying a WAF rule set specifically for SQL injection to provide temporary protection until patching is complete.

Why prioritize this

This vulnerability merits immediate attention due to its HIGH severity, remote exploitability, public exploit availability, and direct impact on the authentication boundary. The absence of authentication requirements and the criticality of voting systems in organizational processes demand rapid remediation. The disclosure date (2026-07-04) and modification date (2026-07-06) suggest active monitoring and potential rapid exploitation in the wild.

Risk score, explained

The CVSS v3.1 score of 7.3 (HIGH) reflects: Network-based attack vector with low attack complexity, no privileges required, no user interaction needed, partial compromise of confidentiality, integrity, and availability. The score does not account for the amplifying factor of public exploit availability and criticality of the affected system (voting/administrative processes), which warrant treating this as higher priority than the base score alone suggests.
