## What is CVE-2023-34452?

CVE-2023-34452 is a medium-severity cross-site scripting vulnerability in Getgrav Grav, published on 14 Jun 2023. 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

Grav is a flat-file content management system. In versions 1.7.42 and prior, the "/forgot_password" page has a self-reflected cross-site scripting vulnerability that can be exploited by injecting a script into the "email" parameter of the request. While this vulnerability can potentially allow an attacker to execute arbitrary code on the user's browser, the impact is limited as it requires user interaction to trigger the vulnerability. As of time of publication, a patch is not available. Server-side validation should be implemented to prevent this vulnerability.

What it is: CVE-2023-34452 is a medium-severity cross-site scripting vulnerability in Getgrav Grav, published on 14 Jun 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-34452 exists.

Affected product: Getgrav Grav. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
