Summary
Red Hat Security Advisory: satellite/iop-vulnerability-engine-rhel9 container image available as a Technology Preview
Severity
Important
Notes
Topic: A new satellite/iop-vulnerability-engine-rhel9 container image is now available as a Technology Preview 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.

CVE-2026-34993

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. An attacker could exploit this vulnerability by providing untrusted input to the `CookieJar.load()` function. This could potentially lead to arbitrary code execution, allowing the attacker to run malicious code on the affected system. This issue is most likely to occur in applications that allow attacker-controlled files to be loaded.

CVE-2026-78679

A flaw was found in GitPython. A remote attacker with low privileges can exploit a vulnerability in the `TagReference.create()` function, where a positional reference parameter bypasses a security guard. This allows the attacker to supply a specially crafted reference value, such as `--file=<path>`, to read arbitrary files on the system. The contents of these files are then returned within the annotated tag message, leading to information disclosure.

6.5 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2026-87817

A flaw was found in GitPython. This vulnerability allows a remote attacker to execute arbitrary code. By failing to properly validate the git directory location, GitPython allows attackers to impersonate the git directory using tracked files such as gitdir, commondir, and HEAD. An attacker can then place a malicious pre-commit hook in the tracked hooks directory, which executes when a victim calls index.commit() on a cloned or opened repository.
