CVE-2026-65915 is fixed in nltk on 1 platform by DEBIAN-CVE-2026-65915 (version 3.10.0-1), released August 22, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
