## What is CVE-2026-125119?

CVE-2026-125119 is a high-severity vulnerability in Automattic mongoose, published on 9 Nov 2026. 

### Official description

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. From 6.0.0 until 6.13.12, 7.8.13, 8.24.7, and 9.11.4, Mongoose stores the connection-level sanitizeFilter option in Connection.config, but Query.prototype._castConditions() and query casting check other option locations and do not read that configuration. An application that enables sanitizeFilter through mongoose.connect() or createConnection() and passes an attacker-controlled object into a query filter therefore receives a connection that reports the defense as enabled while query selector objects remain unsanitized. A crafted password value using a query operator can match an account record without the expected literal password, while global configuration through mongoose.set('sanitizeFilter') and per-query Model.find().sanitizeFilter() remain unaffected. This issue is fixed in versions 6.13.12, 7.8.13, 8.24.7, and 9.11.4.

Weakness: CWE-943 (Improper Neutralization of Special Elements in Data Query Logic)

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.
