## What is CVE-2024-1646?

CVE-2024-1646 is a high-severity authentication bypass vulnerability in parisneo/lollms-webui, published on 16 Apr 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

parisneo/lollms-webui is vulnerable to authentication bypass due to insufficient protection over sensitive endpoints. The application checks if the host parameter is not '0.0.0.0' to restrict access, which is inadequate when the application is bound to a specific interface, allowing unauthorized access to endpoints such as '/restart_program', '/update_software', '/check_update', '/start_recording', and '/stop_recording'. This vulnerability can lead to denial of service, unauthorized disabling or overriding of recordings, and potentially other impacts if certain features are enabled in the configuration.

Weakness: CWE-288 (Authentication Bypass Using an Alternate Path or Channel)

Affected product: parisneo/lollms-webui. 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.
