Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
knexnpmDescription
knex.js versions before 0.19.5 are vulnerable to SQL Injection attack. Identifiers are escaped incorrectly as part of the MSSQL dialect, allowing attackers to craft a malicious query to the host DB.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for knex, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update knex to 0.19.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2019-10757 is resolved across your whole dependency graph.
Workarounds
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
