CVE-2026-53873 · picklescan - Arbitrary Code Execution via profile.run() Blocklist Bypass

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
