## What is CVE-2024-37162?

CVE-2024-37162 is a medium-severity vulnerability in IdoPesok zsa, published on 7 Jun 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

zsa is a library for building typesafe server actions in Next.js. All users are impacted. The zsa application transfers the parse error stack from the server to the client in production build mode. This can potentially reveal sensitive information about the server environment, such as the machine username and directory paths. An attacker could exploit this vulnerability to gain unauthorized access to sensitive server information. This information could be used to plan further attacks or gain a deeper understanding of the server infrastructure. This has been patched on `0.3.3`.

Weakness: CWE-209 (Generation of Error Message Containing Sensitive Information)

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.
