Oracle published a Security Alert on Oct 24 (CVE-2026-114820, CVSS 9.1) whose Java updates remove the affected eMudhra root CA certificates from the JDK trust store; listed as affected are Java SE 8u511, 11.0.33, 17.0.21, 21.0.13, 25.0.5 and 27.0.1, GraalVM for JDK 17.0.21 and 21.0.13, and GraalVM Enterprise 21.3.20. Oracle's page does not list fixed version numbers and points to its patch availability note and an eMudhra page instead, so check your vendor's build notes. Separately, CPython assigned CVE-2026-115557 (CVSS 9.4) for a defense-in-depth denylist in the ssl module that rejects any chain containing a compromised eMudhra intermediate key; the pull request is approved and marked as a release blocker with backports requested to 3.11-3.15, but it was not merged as of this watch. One aggregator claims a public proof of concept exists for the Java issue; we could not confirm that.

The eight eMudhra intermediate CA keys disclosed on Oct 20 were generated so weakly that anyone can recover them, which means a network attacker could mint certificates those intermediates sign; exposure dates back to April 2025, though no misuse has been found. Browsers block them already, but package managers, CI jobs and API clients that carry their own CA bundle keep trusting the chain until updated. Fixed bundles: certifi 2026.10.19, pip 26.2.2, uv 0.13.4, Node.js 22.23.4/24.22.1/26.12.1, Go 1.27.3/1.26.10, rustls-webpki 0.103.16, webpki-roots 1.0.10, composer/ca-bundle 1.4.16/1.6.0, plus Ubuntu, Debian, Alpine, Fedora and Wolfi ca-certificates. Bun, FreeBSD and Java's JDK cacerts were still unfixed or unconfirmed on Oct 23, and container images keep the old roots until rebuilt.
