## What is CVE-2026-82062?

CVE-2026-82062 is a high-severity missing authorization vulnerability in Mongodb Mongodb, published on 8 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

A security issue in MongoDB Server allows an authenticated user with elevated internal privileges to bypass a disabled feature gate in the applyOps command by specifying an internal replication mode value that was not intended to be client-selectable. This bypass enables execution of container operations that are disabled by default in production configurations, allowing direct storage-engine writes to arbitrary internal storage tables. The authorization check for these operations validates only the operation's namespace, not the actual storage target, enabling writes to unrelated internal metadata or other collections' data.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2026-82062 and fix it if it is affected.

What it is: CVE-2026-82062 is a high-severity missing authorization vulnerability in Mongodb Mongodb, published on 8 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-82062 in the wild and no public exploit code.

Affected packages and fixed versions:
- mongodb (Bitnami): affected from 8.3.0; fixed in 8.3.9

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.
