flawz is a Terminal User Interface (TUI) for browsing the security vulnerabilities (also known as CVEs).

As default it uses the vulnerability database (NVD) from NIST and provides search and listing functionalities in the terminal with different theming options.

For example, to view details on the notorious xz vulnerability:

flawz --feeds 2024 --query xz

Key bindings

Key	Action	Description
k / Up	Scroll Up	Scroll up the list
j / Down	Scroll Down	Scroll down the list
Enter	Select	View the selected CVE details
/	Search	Search for a CVE
