CVE-2023-38877 is a high-severity vulnerability in n/a, published on 28 Sep 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

A host header injection vulnerability exists in gugoan's Economizzer v.0.9-beta1 and commit 3730880 (April 2023). By sending a specially crafted host header in the reset password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This allows an attacker to reset other users' passwords.

Check this codebase for CVE-2023-38877 and fix it if it is affected.

What it is: CVE-2023-38877 is a high-severity vulnerability in n/a, published on 28 Sep 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-2023-38877 exists.

Affected packages and fixed versions:

- gugoan/economizzer (Packagist): affected all versions up to 0.9-beta1; 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.
