Go to dashboardMozilla::CA versions before 20261020 ship a CA bundle containing the emSign ECC Root CA - G3, which chains to intermediate certificates whose private keys are publicly available. An attacker who can intercept or redirect client traffic could use those keys to impersonate a TLS server to affected Perl clients.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-23 21:57 UTC. All times on this page are UTC.
Perl applications using LWP, HTTP::Tiny or other clients that fall back to the Mozilla::CA bundle for TLS trust. Systems where IO::Socket::SSL finds CA certificates in OpenSSL's default locations are not using the bundle, and the sources do not say whether those locations are affected by the same root.
No product ranges from the sources yet.
perl -MMozilla::CA -e 'print $Mozilla::CA::VERSION' or cpanm --info Mozilla::CA to read the installed version.20261020 or later.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
Mozilla::CA versions before 20261020 for Perl provide a CA certificate bundle containing a root linked to compromised intermediates.
The bundle includes "emSign ECC Root CA - G3", which provides a trust path for intermediate certificates whose private keys are publicly available.
An attacker able to intercept or redirect client traffic may use these keys to impersonate a TLS server.
LWP, HTTP::Tiny and other clients normally use IO::Socket::SSL, which looks for CA certificates in OpenSSL's default locations before falling back to Mozilla::CA.
Configuration and environment variables can override this selection. Users should check which CA store their client uses. If it uses the system store, check for and install the operating system vendor's updates for this incident.
