CVE-2026-113812
Description
A flaw was found in Mozilla::CA. The Certificate Authority (CA) bundle includes a root certificate linked to compromised intermediate certificates. A remote attacker capable of intercepting or redirecting network traffic could exploit this flaw using the compromised keys to impersonate a Transport Layer Security (TLS) server, leading to the interception or disclosure of sensitive encrypted communications.
Security Bulletin
Statement
Red Hat Enterprise Linux is not affected because perl-Mozilla-CA RPM packages do not bundle its own CA certificates; instead, downstream patches redirect certificate verification to the system trust store provided by the ca-certificates package.
Mitigation
See the security bulletin for a detailed mitigation procedure.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Authentication
Technical Impact: Bypass Protection Mechanism; Gain Privileges or Assume Identity
When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The product might connect to a malicious host while believing it is a trusted host, or the product might be deceived into accepting spoofed data that appears to originate from a trusted host.
