CVE-2019-12760 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
parso is a Python parser that supports error recovery and round-trip parsing for different Python versions.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data. A deserialization vulnerability exists in the way parso handles grammar parsing from the cache. Cache loading relies on pickle and, provided that an evil pickle can be written to a cache grammar file and that its parsing can be triggered, this flaw leads to Arbitrary Code Execution.
