## What is GHSA-f5cv-xrv9-r8w7?

GHSA-f5cv-xrv9-r8w7 is a SQL injection vulnerability in express-cart, published on 1 Sep 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Versions of `express-cart` before 1.1.8 are vulnerable to NoSQL injection. 

The vulnerability is caused by the lack of user input sanitization in the login handlers. In both cases, the customer login and the admin login, parameters from the JSON body are sent directly into the MongoDB query which allows to insert operators. 

These operators can be used to extract the value of the field blindly in the same manner of a blind SQL injection. In this case, the `$regex` operator is used to guess each character of the token from the start.

## Recommendation

Update to version 1.1.8 or later.

Affected packages and fixed versions:
- express-cart (npm): affected all versions; fixed in 1.1.8
- express-cart (npm): affected all versions; fixed in 1.1.8

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
