CVE-2026-97030
Description
A flaw was found in Go's html/template component. This vulnerability allows cross-site scripting (XSS) due to improper escaping of the 'yield' keyword during template processing. A remote attacker could exploit this flaw by providing crafted input to an affected template, leading to arbitrary script execution in a user's web browser.
Statement
This vulnerability is rated as Moderate severity because exploitation requires victim interaction through a web browser and is contingent on an application processing untrusted input within templates that employ the 'yield' keyword. In Red Hat environments, Go is predominantly utilized for backend management daemons, container tooling, and command-line utilities rather than serving dynamic web interfaces via this package. Consequently, typical deployments do not expose web-rendered content to untrusted clients, substantially limiting the attack surface across supported products.
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).
