CVE-2026-14535

A flaw was found in the fickling library, versions up to and including 0.1.11. A logic error in the security analysis passes allows an attacker to bypass intended safety checks during pickle deserialization. This vulnerability enables the invocation of arbitrary standard library modules, leading ...

CVE-2026-14534

A flaw was found in the fickling library, which is designed to safely handle Python pickle data. The library's security checks in versions up to and including 0.1.10 fail to properly identify and block certain dangerous Python standard library modules during deserialization. This oversight allows...
