What it is
Your app is built on code libraries: pieces other people wrote, pulled in by name. AI tools sometimes make up a name that sounds right but doesn’t exist, and sometimes pick one that exists but was abandoned years ago, or one with a known security hole. Attackers know this. They register the made-up names and fill them with harmful code, so the next person whose tool remembers the name installs it.
Even real, well-kept libraries need updating. One with a published security hole is an open door with a public map to it.
What it looks like from your side
Setup steps that fail with “package not found”. Warnings during builds that everyone ignores. A security questionnaire asking how you track vulnerable libraries, and no answer. Or nothing at all, until a provider or a customer’s scanner flags it.
What it costs if you ignore it
A harmful library runs with all the access your app has: your database, your keys, your users’ data. An abandoned one means the next security fix never comes. A known hole means you’re relying on nobody bothering to try it. Enterprise buyers ask about this directly, and “we don’t know” fails the questionnaire.
How to check it yourself in 30 seconds
- If your code is on GitHub, open the project and click the Security tab, then Dependabot alerts. If alerts are on, you’ll see a list of known problems in your libraries, each with a severity. If it says alerts are off, turn them on. It’s one click and it’s free.
- Open the file called
package.jsonin your project, orrequirements.txtfor a Python app. It lists the libraries your app uses. Pick two or three names you don’t recognise and search for each on npmjs.com or pypi.org. Check when it was last updated and how many people use it. A library with no page, or one last updated years ago, is worth asking about.
Looking is safe. Don’t click “update all” from any dashboard. A careless upgrade can break the app in ways that are hard to trace.
How I fix it
Every library gets checked against the public lists of known security holes and against what it actually does in your app. Made-up or abandoned ones are replaced. Known holes are patched and the app is retested.
Then an automatic check runs on every change so the list can’t drift again, and the report tells you which libraries matter and which are noise.
Find out before your users do.
