GHSA-3HHW-38PF-PXJ6 NLTK: Symlink-based arbitrary file read in IPIPANCorpusReader, bypasses nltk.pathsec entirely

Summary IPIPANCorpusReader nltk/corpus/reader/ipipan.py exposes public methods, channels, domains, categories, and fileidschannels=..., that accept a caller supplied fileids list and read a file via a completely unprotected builtin open call, with no nltk.pathsec involvement at all. A symlink...

GHSA-F833-7JW8-XWRV NLTK: Symlink-based sandbox bypass in FramenetCorpusReader (bypasses the fix for CVE-2026-54292)

This is a new, distinct vulnerability: a bypass of the fix already published as GHSA-xh95-f55m-82fw "Path traversal in NLTK FramenetCorpusReader.frame allows arbitrary XML file read, bypassing the nltk.pathsec sandbox", not a duplicate of it. Summary The original advisory was fixed PR 3581 by...

libvirt: swtpm privilege escalation via symlink following

A flaw was found in libvirt. A local attacker, specifically a process running as the confined swtpm user, could exploit a symlink-following vulnerability in the virFileChownFiles function. By planting a symbolic link within the swtpm state directory, the attacker could trick the root-level libvir...

NLTK: Symlink escape in CorpusReader allows arbitrary local file read outside the corpus root

Summary nltk.corpus.reader.api.CorpusReader.open can be used to read files outside the intended corpus root via a symlink placed inside that root. Although NLTK blocks absolute paths and .. traversal, the current boundary check is only lexical and does not account for symlink resolution. This lea...
