## What is CVE-2019-17633?

CVE-2019-17633 is a high-severity vulnerability in The Eclipse Foundation Eclipse Che, published on 19 Dec 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

For Eclipse Che versions 6.16 to 7.3.0, with both authentication and TLS disabled, visiting a malicious web site could trigger the start of an arbitrary Che workspace. Che with no authentication and no TLS is not usually deployed on a public network but is often used for local installations (e.g. on personal laptops). In that case, even if the Che API is not exposed externally, some javascript running in the local browser is able to send requests to it.

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

What it is: CVE-2019-17633 is a high-severity vulnerability in The Eclipse Foundation Eclipse Che, published on 19 Dec 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-2019-17633 in the wild and no public exploit code.

Affected product: The Eclipse Foundation Eclipse Che. 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.
