No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)

CWE-89 · Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Root cause

The query text is built by concatenating user input. The database cannot tell where the data ends and the command begins.

The bug in code

The whole CWE-89 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

Fixed

ts
const owner = req.query.owner;const rows = await db.query(  "SELECT * FROM files WHERE owner = $1",  [owner]);
