描述

Summary

Eight eMudhra (emSign) intermediate CA certificates have recoverable private keys (Mozilla bug 2083449). Clients whose trust store still contains emSign ECC Root CA - G3, emSign Root TLS CA - G3 or AAA Certificate Services can be impersonated by an on-path attacker.

The following packages are affected

  • certifi earlier than 2026.10.19 (REST transports).
  • httplib2 earlier than 0.32.1, used by google-api-python-client and google-auth-httplib2; its bundled trust store is used when certifi is not installed.
  • grpcio earlier than 1.84.1 (gRPC transports); bundled root store, does not read the operating system trust store.

You can take the following actions to resolve these issues

  • Upgrade certifi to 2026.10.19 or later.
  • Upgrade httplib2 to 0.32.1 or later.
  • Upgrade grpcio to 1.84.1 or later. Patch releases for earlier release lines are being published; see GHSA-2xm2-c8xx-p9vh for the current list of fixed versions.
