What is CVE-2025-58367?

DeepDiff, a tool for identifying differences within Python data, is susceptible to a vulnerability that allows for class pollution through its Delta class constructor. When exploited, it can lead to Denial of Service and Remote Code Execution due to insecure Pickle deserialization. Specifically, attackers can manipulate the deepdiff.serialization.SAFE_TO_IMPORT attribute to include unsafe classes, potentially enabling the execution of arbitrary Python code if user-controlled input is processed. This vulnerability affects all DeepDiff versions from 5.0.0 to 8.6.0 and has been resolved in version 8.6.1.

Human OS v1.0:
Ageing Is an Unpatched Zero-Day Vulnerability.

Remediate biological technical debt. Prime Ageing uses 95% high-purity SIRT6 activation to maintain genomic integrity and bolster systemic resilience.
