## What is CVE-2022-37767?

CVE-2022-37767 is a critical code injection vulnerability in n/a, published on 12 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Pebble Templates 3.1.5 allows attackers to bypass a protection mechanism and implement arbitrary code execution with springbok. NOTE: the vendor disputes this because input to the Pebble templating engine is intended to include arbitrary Java code, and thus either the input should not arrive from an untrusted source, or else the application using the engine should apply restrictions to the input. The engine is not responsible for validating the input.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2022-37767 and fix it if it is affected.

What it is: CVE-2022-37767 is a critical code injection vulnerability in n/a, published on 12 Sep 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-37767 in the wild and no public exploit code.

Affected packages and fixed versions:
- io.pebbletemplates:pebble (Maven): affected all versions up to 3.1.5; no fix listed
- io.pebbletemplates:pebble (Maven): affected all versions up to 3.1.5; no fix listed

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.
