cve-2026-47241

The cve-2026-47241 tag covers a denial-of-service vulnerability in Ruby’s Net::IMAP client library. The issue affects older net-imap versions and is addressed in releases 0.6.5 and 0.5.15. Coverage focuses on identifying Ruby applications, services, scheduled jobs, CI runners, packaged tools, and vendor bundles that include an affected version. It also highlights the need to update current 0.6-line deployments to 0.6.5, move older pinned deployments to 0.5.15, and confirm the dependency version loaded at runtime rather than relying only on a manifest. The vulnerable command-handling path is described as narrow but relevant to deployed Ruby software.
