Vulnerability from csaf_redhat - Published: 2026-08-06 20:11 - Updated: 2026-08-13 22:51
Summary
Red Hat Security Advisory: General availability of the satellite/iop-advisor-frontend-rhel9 container image
Severity
Important
Notes
Topic: A new satellite/iop-advisor-frontend-rhel9 container image is now generally available in the Red Hat container registry.
Details: Red Hat Lightspeed in Satellite analyzes system health and configuration by applying predefined rules to a small set of local data, such as installed packages, running services, and configuration settings. When you install Red Hat Lightspeed in Satellite locally, you can generate Red Hat Lightspeed recommendations without sending system data to Red Hat services.

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the `expand()` function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-loop blocking. This can result in a Denial of Service (DoS) for the affected system.

Impact Important

A flaw was found in fast-uri. This vulnerability occurs because fast-uri fails to properly convert Unicode (Internationalized Domain Name - IDN) hostnames for HTTP-family URLs. This can lead to a situation where security policies, such as denylists or redirect validations, are bypassed when applications use fast-uri to enforce these policies before passing the URL to another parser. A remote attacker could exploit this to circumvent security controls and potentially access unauthorized resources or perform malicious redirects.

CWE-551 - Incorrect Behavior Order: Authorization Before Parsing and Canonicalization
