CVE-2026-81726
NLTK through 3.10.3 contains a path traversal vulnerability in its model-artifact APIs. The root cause is that TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs bypass pathsec enforcement by performing raw file operations on caller-controlled paths, allowing attack...
Linux Distros Unpatched Vulnerability : CVE-2026-81726
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on...
PT-2026-82621
Name of the Vulnerable Software and Affected Versions NLTK versions prior to 3.10.4 Description Path traversal occurs in model-artifact APIs when pathsec is enabled. The issue arises from the use of raw file operations on caller-controlled paths, which allows bypassing pathsec enforcement. This...
