Directory Traversal

Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Directory Traversal through IPIPANCorpusReader, CrubadanCorpusReader, and LinThesaurusCorpusReader in nltk/corpus/reader/ipipan.py,...

PYSEC-2026-3737

NLTK versions before 3.10.3 contain a path traversal vulnerability in corpus readers that reopen root-derived paths using built-in open instead of nltk.pathsec.open, allowing symlinks to escape trusted roots. Attackers who stage symlinked corpus files under a trusted data root can disclose...

CVE-2026-55540

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.51, ispathwithindirectory uses os.path.abspath rather than os.path.realpath for the workspace boundary. A symlink inside workspace can point outside and still pass the check, allowing readfile and other code tools to access files...

CVE-2026-79676 NLTK before 3.10.3 Path Traversal via Symlink Bypass

NLTK versions before 3.10.3 contain a path traversal vulnerability in corpus readers that reopen root-derived paths using built-in open instead of nltk.pathsec.open, allowing symlinks to escape trusted roots. Attackers who stage symlinked corpus files under a trusted data root can disclose...

CVE-2026-79676

NLTK versions before 3.10.3 are affected by a path traversal vulnerability in its corpus readers. The root cause is that these readers reopen root-derived paths using the built-in open() instead of nltk.pathsec.open(), which fails to resolve symlinks confined to a trusted root. An attacker who ca...

GHSA-CH89-H4R2-C8F8 PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks

Summary PraisonAI's praisonai.code tool wrappers exported as CODETOOLS for agents expose a workspace setting that the module itself treats as a path-traversal security boundary — readfile, writefile, applydiff, and searchreplace explicitly call ispathwithindirectory and return "… is outside the...

CVE-2026-55540 PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.51, ispathwithindirectory uses os.path.abspath rather than os.path.realpath for the workspace boundary. A symlink inside workspace can point outside and still pass the check, allowing readfile and other code tools to access files...

CVE-2026-55540

CVE-2026-55540 is a path traversal vulnerability in PraisonAI , a multi-agent teams system. The function is_path_within_directory() relies on os.path.abspath() instead of os.path.realpath() to enforce the workspace boundary, so a symlink placed inside the workspace can resolve to a path outside i...
