CVE-2026-7746: Pharmacy Management System SQLi Flaw

CVE-2026-7746 Overview

CVE-2026-7746 is a SQL injection vulnerability in SourceCodester Web-based Pharmacy Product Management System 1.0. The flaw resides in the /product_expiry/edit-admin.php script, where the ID parameter is passed to a database query without proper sanitization. Authenticated attackers can manipulate this parameter remotely to inject arbitrary SQL statements. The exploit is publicly disclosed, increasing the likelihood of opportunistic abuse against exposed installations. The weakness is classified under CWE-74 (Improper Neutralization of Special Elements in Output).

Critical Impact
Remote attackers with low privileges can execute arbitrary SQL queries against the backend database, exposing or modifying pharmacy records.

Technical Details for CVE-2026-7746

Vulnerability Analysis

The vulnerability resides in the administrative product expiry editor of the SourceCodester Web-based Pharmacy Product Management System. The edit-admin.php script accepts an ID parameter from the HTTP request and concatenates it directly into a SQL statement. Because the application does not sanitize, escape, or use parameterized queries, attacker-controlled input becomes part of the executed SQL.

A successful attack allows the threat actor to read arbitrary tables, modify records, or extract authentication data stored in the application database. The attack complexity is low and only requires a network path to the application. The exploit details are publicly available through external disclosure platforms, which increases the risk of automated scanning and exploitation.

Root Cause

The root cause is missing input neutralization on the ID parameter before it is used in a backend SQL query. The application trusts request parameters without applying prepared statements or whitelist validation. This pattern aligns with CWE-74, where untrusted data flows into a downstream interpreter.

Attack Vector

The attack vector is network-based and requires low-level authenticated access to the administrative interface. An attacker sends a crafted HTTP request to /product_expiry/edit-admin.php containing a malicious ID value. The injected payload is executed in the database context, allowing extraction or manipulation of stored data.

No verified proof-of-concept code is included here. Technical details are documented in the GitHub CVE Issue and VulDB #360921.

Detection Methods for CVE-2026-7746

Indicators of Compromise

HTTP requests to /product_expiry/edit-admin.php containing SQL metacharacters such as single quotes, UNION, SELECT, OR 1=1, or comment sequences (--, /*) in the ID parameter.
Web server access logs showing repeated requests to edit-admin.php from a single source with varying ID values.
Database error messages or unusually long response times tied to requests against the affected endpoint.

Detection Strategies

Inspect web application firewall logs for SQL injection signatures targeting the ID query string parameter.
Correlate authentication events with subsequent abnormal database query patterns originating from the application service account.
Apply runtime database query monitoring to flag unexpected UNION-based or boolean-based queries from the pharmacy application.

Monitoring Recommendations

Enable verbose access logging on the web server hosting the pharmacy application and forward logs to a centralized analytics platform.
Alert on outbound database queries that reference system tables such as information_schema from the application user.
Review administrative account activity for unauthorized record modification within the product_expiry workflow.

How to Mitigate CVE-2026-7746

Immediate Actions Required

Restrict network access to the pharmacy application so that only trusted administrative networks can reach /product_expiry/edit-admin.php.
Enforce strong, unique credentials for administrative accounts and rotate any credentials that may have been exposed.
Deploy a web application firewall rule that blocks SQL metacharacters in the ID parameter until a vendor patch is applied.

Patch Information

No official vendor patch is referenced in the published advisory. Operators should monitor the SourceCodester Blog and the VulDB entry for fix availability. Until a patch ships, organizations should consider taking the application offline if it is exposed to untrusted networks.

Workarounds

Modify edit-admin.php to validate that the ID parameter is a strict integer before any database operation.
Replace string-concatenated SQL with parameterized queries or prepared statements throughout the application.
Place the application behind an authenticated reverse proxy that enforces parameter type validation at the edge.
Disable or remove the affected endpoint if the product expiry workflow is not actively used.
