## What is CVE-2021-32691?

CVE-2021-32691 is a high-severity authentication bypass vulnerability in ApollosProject apollos-apps, published on 16 Jun 2021. 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

Apollos Apps is an open source platform for launching church-related apps. In Apollos Apps versions prior to 2.20.0, new user registrations are able to access anyone's account by only knowing their basic profile information (name, birthday, gender, etc). This includes all app functionality within the app, as well as any authenticated links to Rock-based webpages (such as giving and events). There is a patch in version 2.20.0. As a workaround, one can patch one's server by overriding the `create` data source method on the `People` class.

Weakness: CWE-287 (Improper Authentication), CWE-303 (Incorrect Implementation of Authentication Algorithm)

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.
