NLTK: pathsec SSRF protection can be bypassed when a proxy is configured

Summary Current NLTK source reopens SSRF in proxied environments. pathsec.urlopen validates the requested hostname locally, but once proxy inheritance is enabled the real fetch is performed by the proxy rather than by the validated direct-connect socket path. Details - Vulnerability type:...

CVE-2026-78682

A flaw was found in NLTK. When an HTTP proxy is configured, a server-side request forgery SSRF vulnerability exists in the nltk.pathsec.urlopen function. An attacker can exploit this by providing a seemingly valid public URL, which the proxy then forwards to an internal service without proper...
