Details
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-m273-6v24-x4m4. This link is maintained to preserve external references.
Original Description
picklescan before 0.0.33 contains an arbitrary file writing vulnerability that allows attackers to bypass the dangerous blocklist by using distutils.file_util.write_file. Attackers can construct malicious pickle objects to overwrite critical system files and achieve denial of service or remote code execution.
Severity
9.8 (Critical)
