An upstream fix is merged but not yet released — mitigate (WAF / firewall / segmentation) until the release ships, then apply it.

A vulnerability has been found in HKUDS nanobot up to 0.2.1. This affects the function _download_image_data_url of the file nanobot/providers/image_generation.py of the component Provider-returned Image URL Handler. The manipulation leads to server-side request forgery. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of the patch is 5095. It is recommended to apply a patch to fix this issue. The vendor explains: "We confirm that provider-returned image URLs required the same SSRF protections applied to other network retrieval paths. (...) The patch is currently available on main and is planned for the next patch release, v0.3.1."
