## What is CVE-2019-11278?

CVE-2019-11278 is a high-severity vulnerability in Cloud Foundry UAA Release (OSS), published on 26 Sep 2019. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

CF UAA versions prior to 74.1.0, allow external input to be directly queried against. A remote malicious user with 'client.write' and 'groups.update' can craft a SCIM query, which leaks information that allows an escalation of privileges, ultimately allowing the malicious user to gain control of UAA scopes they should not have.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Check this codebase for CVE-2019-11278 and fix it if it is affected.

What it is: CVE-2019-11278 is a high-severity vulnerability in Cloud Foundry UAA Release (OSS), published on 26 Sep 2019. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-11278 in the wild and no public exploit code.

Affected product: Cloud Foundry UAA Release (OSS). No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
