## What is CVE-2020-1925?

CVE-2020-1925 is a high-severity server-side request forgery vulnerability in Apache Olingo, published on 9 Jan 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Apache Olingo versions 4.0.0 to 4.7.0 provide the AsyncRequestWrapperImpl class which reads a URL from the Location header, and then sends a GET or DELETE request to this URL. It may allow to implement a SSRF attack. If an attacker tricks a client to connect to a malicious server, the server can make the client call any URL including internal resources which are not directly accessible by the attacker.

Weakness: CWE-918 (Server-Side Request Forgery)

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.
