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

Evidence notes

The login.php file constructs its authentication query via direct string concatenation of raw POST parameters, allowing authentication bypass. Additionally, delete.php executes a DELETE query with no authentication check and no validation of the id parameter, allowing arbitrary product deletion or blind SQL injection.
