GHSA-QVV7-CG9C-W4X3 Natural Language Toolkit (NLTK): DNS-rebinding SSRF filter bypass in nltk.pathsec.urlopen (nltk.download / nltk.data.load) defeats ENFORCE mode

Summary nltk.pathsec provides an SSRF filter that NLTK documents as a security control, blocking loopback, private, link-local, and multicast ranges including obfuscated forms and recommending strict ENFORCE mode for security-sensitive environments. The filter is bypassable by DNS rebinding:...

GHSA-6HM5-JGCP-P838 Natural Language Toolkit (NLTK): Path Traversal in NKJPCorpusReader leads to Arbitrary File Read and bypasses the nltk.pathsec sandbox (ENFORCE=True)

Summary A path-traversal vulnerability in NKJPCorpusReader allows an attacker who can influence the fileids argument of its public read methods header, raw, words, sents, taggedwords to read files outside the corpus root. The reader builds the file path with no containment check and opens it with...

GHSA-XH95-F55M-82FW Natural Language Toolkit (NLTK) has path traversal in FramenetCorpusReader.frame() that allows arbitrary XML file read, bypassing the nltk.pathsec sandbox (ENFORCE=True)

Summary FramenetCorpusReader.framename interpolates a caller-supplied frame name into an XML file path that is read with the builtin open, bypassing CorpusReader.open and the nltk.pathsec sandbox — including strict ENFORCE=True mode. A ../ sequence in the name escapes the corpus root, yielding an...

Improper Access Control

github.com/kyverno/kyverno is vulnerable to Improper Access Control. The vulnerability is due to incorrect handling of multiple policy exceptions in enforce mode, which allows an attacker to bypass enforced policies by leveraging a less restrictive exception even when a more restrictive exception...

GHSA-GG4X-FGG2-H9W9 Bypassing Kyverno Policies via Double Policy Exceptions

Summary If a cluster has a Kyverno policy in enforce mode and there are two exceptions, this allows the policy to be bypassed, even if the first exception is more restrictive than the second. Details The following policy was applied: yaml apiVersion: kyverno.io/v1 kind: ClusterPolicy metadata:...
