CVE-2026-45246Public exploit

Local credential disclosure via permissive config rewrite

Published May 18, 2026 · Updated May 18, 2026

Insecure file permissions in Summarize before 0.15.1 allow local users to read API keys and provider credentials from its configuration. The refresh-free path writes a temporary replacement for ~/.summarize/config.json using process-umask permissions instead of preserving owner-only access. Exposure requires a shared Unix-like host, stored secrets, a permissive umask, and execution of summarize refresh-free; the consequence is credential disclosure.
