HighCVE-2025-64343conda · constructor(conda) Constructor: Excessive permissions during and after installation(conda) Constructor is a tool that enables users to create installers for conda package collections. In versions 3.12.2 and below, the installation directory inherits permissions from its parent directory. Outside of restricted directories, the permissions are very permissive and often allow write access by authenticated users. Any logged in user can make modifications during the installation for both single-user and all-user installations. This constitutes a local attack vector if the installation is in a directory local users have access to. For single-user installations in a shared directory, these permissions persist after the installation. This issue is fixed in version 3.13.0.EPSS0.13%UnknownCVE-2025-49823conda · constructorConda Constructor Command Injection via Unsanitized User Input (Low)(conda) Constructor is a tool which allows constructing an installer for a collection of conda packages. Prior to version 3.11.3, shell installer scripts process the installation prefix (user_prefix) using an eval statement, which executes unsanitized user input as shell code. Although the script runs with user privileges (not root), an attacker could exploit this by injecting arbitrary commands through a malicious path during installation. Exploitation requires explicit user action. This issue has been patched in version 3.11.3.EPSS0.16%
