Insecure Sensitive HTTP Header Sanitization

Summary

A flaw was found in foreman-mcp-server. This component utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers, which are treated as authentication credentials, at an informational level. The other, when debug logging is enabled, incompletely sanitizes HTTP request headers, leading to the cleartext logging of sensitive information such as authorization tokens and API keys. This vulnerability can result in a confidentiality breach, as sensitive authentication data is persisted in plain text within container logs, increasing the risk if logs are forwarded to a centralized platform.

This Moderate impact flaw in `foreman-mcp-server` within Red Hat Satellite can lead to a confidentiality breach. The component logs sensitive session identifiers, which are treated as authentication credentials, at an informational level by default. Additionally, when debug logging is enabled, HTTP request headers containing authorization tokens and API keys are incompletely sanitized and logged in cleartext. This exposes sensitive authentication data in plain text within container logs, increasing risk if logs are aggregated or accessed by unauthorized parties. Red Hat severity: Moderate — CVSS 6.2 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-532. Fixed by RHSA-2026:28438 — update the affected packages (`sudo dnf update`). Affected Red Hat products: Red Hat Satellite 6.19.
