## What is CVE-2026-82069?

CVE-2026-82069 is a medium-severity 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's query statistics serialization on the router allows users with monitoring privileges to access unredacted search query text from other users' operations. An improper conditional check in the serialization logic causes the data redaction mechanism to be bypassed when processing search queries through the sharded cluster router. This results in sensitive query literals being stored and made accessible through the query statistics interface.

Weakness: CWE-212 (Improper Removal of Sensitive Information Before Storage or Transfer)

Check this codebase for CVE-2026-82069 and fix it if it is affected.

What it is: CVE-2026-82069 is a medium-severity 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-2026-82069 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.
