  "title": "Pickle safety-check bypass in fickling",
  "summary": "fickling releases through 0.1.12 can incorrectly approve malicious pickle data when assessing calls exposed through trusted standard-library modules. An attacker who can provide a pickle that an application passes to fickling.load() may cause code execution or file writes with the application's privileges.",
  "mitigation": "Do not use affected fickling versions as the sole safety gate for untrusted pickle data; reject untrusted pickles or process them in a strongly isolated environment. Apply a vendor release that removes this trust behavior when one is available.",
