## What is CVE-2026-45246?

CVE-2026-45246 is a medium-severity vulnerability in steipete summarize, published on 18 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Summarize prior to 0.15.1 contains an insecure file permission vulnerability in the refresh-free configuration rewrite path that allows local users to read sensitive credentials by exploiting default filesystem permissions. When the refresh-free path rewrites the configuration file, it creates the replacement with default process umask permissions instead of preserving the original file permissions, exposing the config file containing API keys and provider credentials to other local users on shared Unix-like systems.
