The private keys of eight eMudhra intermediate CA certificates have been compromised. They chain to roots trusted by the Mozilla, Microsoft, Apple and Chrome root programs and by many downstream trust stores.
We are urgently applying patches to Determinate Secure Packages Rolling, 26.05, and 25.11.
