Last modified
CVE-2026-81726 is a high-severity vulnerability rated 7/10 on the CVSS scale. NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled.. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
