Doc Text:
A deserialization flaw was found in python-diskcache. This component uses Python pickle for serialization by default. An attacker with write access to the cache directory can exploit this vulnerability to achieve arbitrary code execution when a victim application reads from the cache. The impact of this flaw is scoped to the user running the tool.
