  "details" : [ "A flaw was found in NLTK. A Server-Side Request Forgery (SSRF) vulnerability allows an attacker to influence a URL passed to NLTK's network-loading helpers. This occurs because the `nltk.pathsec.validate_network_url()` function fails to properly identify and reject IP addresses within the RFC 6598 shared address space (100.64.0.0/10). This could lead to the exposure of non-public infrastructure reachable from the application host, resulting in confidentiality exposure." ],
