Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A Local File Inclusion (LFI) vulnerability exists in the '/reinstall_extension' endpoint of the parisneo/lollms-webui application, specifically within the `name` parameter of the `@router.post("/reinstall_extension")` route. This vulnerability allows attackers to inject a malicious `name` parameter, leading to the server loading and executing arbitrary Python files from the upload directory for discussions. This issue arises due to the concatenation of `data.name` directly with `lollmsElfServer.lollms_paths.extensions_zoo_path` and its use as an argument for `ExtensionBuilder().build_extension()`. The server's handling of the `__init__.py` file in arbitrary locations, facilitated by `importlib.machinery.SourceFileLoader`, enables the execution of arbitrary code, such as command execution or creating a reverse-shell connection. This vulnerability affects the latest version of parisneo/lollms-webui and can lead to Remote Code Execution (RCE) when the application is exposed to an external endpoint or the UI, especially when bound to `0.0.0.0` or in `headless mode`. No user interaction is required for exploitation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

Latest version of parisneo/lollms-webui from main branch (commit 41dbb1b3f2e78ea276e5269544e50514252c0c25 or later)

  1. 1. Clone or pull the latest version of the lollms-webui repository: `git pull origin main` or `git clone https://github.com/parisneo/lollms-webui.git`
  2. 2. Verify the fix has been applied by checking that the commit 41dbb1b3f2e78ea276e5269544e50514252c0c25 is included in your version
  3. 3. Look for the patched code in the reinstall_extension endpoint - ensure it now validates and sanitizes the `name` parameter before use
  4. 4. Restart the lollms-webui service to apply the updated code
  5. 5. If the application is exposed externally (bound to 0.0.0.0 or in headless mode), verify the vulnerability is no longer exploitable by testing the /reinstall_extension endpoint with malicious path traversal input
