  "title": "Dotted attribute-path safety-check bypass in fickling",
  "summary": "fickling through version 0.1.12 can incorrectly approve pickles containing dotted attribute references during safety analysis. An attacker who can supply a pickle that is subsequently loaded through the affected loading path can cause arbitrary code execution despite the safety check.",
  "mitigation": "Do not load untrusted pickles with fickling, including when its safety check reports that they are safe; reject them or process them in an isolated environment. No fixed version is identified in the evidence, so track for a release that explicitly corrects dotted attribute-path analysis before relying on this check.",
