Doc Text:
A flaw was found in Scapy. This vulnerability allows arbitrary code execution due to insecure deserialization, which occurs when converting stored data back into an active program object without proper validation. By tricking a user into loading a maliciously crafted session file, an attacker can execute arbitrary Python commands with the permissions of the application.

Description OSIDB Bzimport 2026-11-13 20:41:58 UTC
Scapy before 2.7.0 contains an insecure deserialization vulnerability in the load_session function that allows attackers to execute code by supplying a malicious pickle session file. Attackers can trick users into loading a crafted .pkl.gz file via the -s option or conf.session, executing embedded Python code through __reduce__().
