## What is CVE-2022-31140?

CVE-2022-31140 is a high-severity vulnerability in CuyZ Valinor, published on 11 Jul 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Valinor is a PHP library that helps to map any input into a strongly-typed value object structure. Prior to version 0.12.0, Valinor can use `Throwable#getMessage()` when it should not have permission to do so. This is a problem with cases such as an SQL exception showing an SQL snippet, a database connection exception showing database IP address/username/password, or a timeout detail / out of memory detail. Attackers could use this information for potential data exfiltration, denial of service attacks, enumeration attacks, etc. Version 0.12.0 contains a patch for this vulnerability.

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.
