## What is CVE-2019-0996?

CVE-2019-0996 is a medium-severity vulnerability in Microsoft Azure DevOps Server 2019, published on 12 Jun 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A spoofing vulnerability exists in Azure DevOps Server when it improperly handles requests to authorize applications, resulting in a cross-site request forgery. An attacker who successfully exploited this vulnerability could bypass OAuth protections and register an application on behalf of the targeted user.
To exploit this vulnerability, an attacker would need to create a page specifically designed to cause a cross-site request. The attacker would then need to convince a targeted user to click a link to the malicious page.
The update addresses the vulnerability by modifying how Azure DevOps Server protects application registration requests.

Weakness: CWE-352 (Cross-Site Request Forgery)

Check this codebase for CVE-2019-0996 and fix it if it is affected.

What it is: CVE-2019-0996 is a medium-severity vulnerability in Microsoft Azure DevOps Server 2019, published on 12 Jun 2019. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2019-0996 in the wild and no public exploit code.

Affected product: Microsoft Azure DevOps Server 2019. 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.
