    18.0.3, and 18.1 before 18.1.1 that could have allowed unauthenticated attackers to upload arbitrary files
    to public projects by sending crafted API requests, potentially leading to resource abuse and unauthorized
    content storage. (CVE-2025-1754)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
