Why

  • warnVulnerability

    NLTK: Model-artifact APIs bypass pathsec and touch files outside allowed roots

  • warnVulnerability

    NLTK: WekaClassifier passes an unvalidated caller-controlled model path to the weka JVM, bypassing nltk.pathsec containment (fixed in 3.10.4)

Provenance

A registry signature proves the registry served these bytes unaltered. Build provenance proves which workflow built them from which commit; a stolen publishing token can fake the first but not the second.

Signature
Not signed
Build provenance
None, and no earlier version had any
