Vulnerability Title
picklescan - Arbitrary Code Execution via profile.run() Blocklist Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
picklescan before 1.0.4 contains an incomplete blocklist for the profile module that fails to block the module-level profile.run() function, allowing attackers to achieve arbitrary code execution via exec(). Attackers can craft malicious pickle files calling profile.run(statement) to execute arbitrary Python code while picklescan reports zero security issues.
