SUSE CVE-2026-78682

NLTK before 3.10.3 contains a server-side request forgery vulnerability in nltk.pathsec.urlopen and callers nltk.data.load, nltk.downloader.Downloader.index/download when an HTTP proxy is configured. pathsec.urlopen validates the requested hostname locally, but proxy-handler inheritance disables...

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...

The vulnerabilities of the functions pathsec.urlopen(), nltk.data.load(), Downloader.index(), and Downloader.download() in the NLTK library for symbolic and statistical processing of natural language allow attackers to perform SSRF attacks.

The vulnerabilities of the functions pathsec.urlopen, nltk.data.load, Downloader.index, and Downloader.download in the NLTK library for symbolic and statistical processing of natural language are related to insufficient validation of requests on the server side. Exploiting these vulnerabilities...
