CVE-2026-13551: Baptism Management System SQLi Flaw

CVE-2026-13551 Overview

CVE-2026-13551 is a SQL injection vulnerability in itsourcecode Baptism Information Management System 1.0. The flaw resides in the /editBaptism.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 attacks against exposed instances. The vulnerability is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Remote unauthenticated attackers can inject SQL through the ID parameter of /editBaptism.php, potentially disclosing, modifying, or destroying database contents.

Technical Details for CVE-2026-13551

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw in a PHP-based web application. The /editBaptism.php endpoint accepts an ID argument through an HTTP request and concatenates it into a SQL statement without parameterization or input validation. An attacker can supply crafted SQL syntax as the value of ID, altering the intended query logic executed by the backend database.

Because the attack originates from the network and requires no authentication or user interaction, adversaries can automate exploitation using standard tooling such as sqlmap. Successful exploitation can lead to unauthorized read and write access to records including personal information stored in the baptism management database.

Root Cause

The root cause is the direct inclusion of user-supplied input in a SQL query string. The application does not use prepared statements, parameterized queries, or an allow-list validation routine on the ID parameter. This design flaw is categorized under [CWE-74], improper neutralization of special elements in a downstream component.

Attack Vector

An attacker sends an HTTP request to /editBaptism.php with a manipulated ID value containing SQL metacharacters. The malicious payload is passed to the database engine, which executes attacker-controlled query fragments. No credentials or prior session are required, and the request can be issued from any network position that reaches the web application.

No verified proof-of-concept code is available in the referenced sources. Refer to the GitHub CVE Issue Discussion and VulDB CVE #CVE-2026-13551 for additional technical context.

Detection Methods for CVE-2026-13551

Indicators of Compromise

HTTP requests to /editBaptism.php containing SQL metacharacters such as single quotes, UNION SELECT, --, OR 1=1, or hex-encoded payloads in the ID parameter.
Unusual database error messages surfacing in application logs referencing malformed queries against the baptism records table.
Repeated automated requests from a single source targeting editBaptism.php with varying ID payloads, consistent with sqlmap or similar tooling.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID query parameter for SQL injection signatures and block anomalous payloads.
Enable database query logging and alert on queries containing tautologies, stacked statements, or UNION operators originating from the application service account.
Correlate web server access logs with database error logs to identify injection attempts and successful data exfiltration patterns.

Monitoring Recommendations

Monitor outbound traffic from the web server for unexpected large responses that may indicate data exfiltration via injected queries.
Track authentication and access anomalies on the underlying MySQL or MariaDB server, particularly unusual SELECT volumes from the application account.
Baseline normal request patterns to /editBaptism.php and alert on deviations in parameter length, character set, or request frequency.

How to Mitigate CVE-2026-13551

Immediate Actions Required

Restrict network access to the Baptism Information Management System, placing it behind authentication or VPN until a patch is available.
Deploy WAF signatures blocking SQL injection payloads targeting the ID parameter of /editBaptism.php.
Audit database logs for prior exploitation attempts and rotate any credentials that may have been exposed.

Patch Information

No official vendor patch has been referenced in the NVD entry at the time of publication. Organizations running itsourcecode Baptism Information Management System 1.0 should monitor the IT Source Code Resource and the GitHub CVE Issue Discussion for updates. Until a fix is released, apply the workarounds below.

Workarounds

Modify /editBaptism.php to use parameterized queries or PDO prepared statements instead of string concatenation for the ID value.
Cast the ID parameter to an integer server-side (for example, $id = (int)$_GET['ID'];) before using it in any SQL statement.
Enforce least privilege on the database account used by the application, restricting it to only the tables and operations required for baptism record management.
Consider taking the application offline if it processes sensitive personal data and no compensating controls can be implemented.
