GHSA-cq46-m9x9-j8w2: Scapy Session Loading Vulnerable to Arbitrary Code Execution via Untrusted Pickle Deserialization

October 22, 2025 (updated November 10, 2025)

An unsafe deserialization vulnerability in Scapy <v2.7.0 allows attackers to execute arbitrary code when a malicious session file is locally loaded via the -s option. This requires convincing a user to manually load a malicious session file.
