CVE-2026-71248 Harsh21Patel CVE debrief

Who should care

Security teams and administrators responsible for Inventory-Management-System-PHP installations should prioritize patching or mitigating this vulnerability to prevent potential authentication bypass and arbitrary product deletion.

Technical summary

The login.php file in Inventory-Management-System-PHP constructs its authentication query via direct string concatenation of raw POST parameters, allowing authentication bypass via a payload such as email=' OR 1=1 LIMIT 1-- -. Separately, delete.php executes mysqli_query($db, 'DELETE FROM product WHERE product_id=' . $_GET['id']) with no authentication check and no validation of the id parameter, allowing an unauthenticated attacker to delete arbitrary product rows or perform blind SQL injection via payloads such as id=0 OR SLEEP(5).

Defensive priority

Critical vulnerability in Inventory-Management-System-PHP, allowing authentication bypass and arbitrary product deletion via SQL injection.

Recommended defensive actions

• Verify the authenticity of user input in login.php and delete.php
• Implement parameterized queries or prepared statements to prevent SQL injection
• Add authentication checks to delete.php
• Validate and sanitize the id parameter in delete.php
• Consider applying patches or updates from the vendor, if available
