What is CVE-2026-53940?

Prior to version 26.5.2, the Conda package manager accepted unvalidated entry-point commands from Python package metadata. This design flaw allowed malicious packages to exploit path traversal or absolute command paths, potentially executing harmful code outside the intended installation prefix. An attacker could overwrite existing entry points or write executable commands to unauthorized paths, leading to execution with the privileges of the installing user. This vulnerability was addressed in version 26.5.2.

Affected Version(s)
