Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Picklescan versions before 0.0.25 can be bypassed by a malicious pickle that uses the linecache and ssl.get_server_certificate functions, which are not on its blacklist. When a victim deserializes such a model, the payload can read local files and leak their contents through DNS lookups to an attacker-controlled domain. Upgrade picklescan to version 0.0.25 or later.
