Last modified
CVE-2026-65915 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. NLTK versions before 3.10.0 contain a logic bug in FileSystemPathPointer.open() where the sandbox validation check compares a normalized path against itself, making the security check permanently inert. Attackers can pass file:// URLs to nltk.data.load() to read arbitrary files accessible to the process user, including credentials and configuration files.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
