CVE-2026-9073 Red Hat CVE debrief

A flaw was found in foreman-mcp-server, which utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers at an informational level, treating them as authentication credentials. The other, when debug logging is enabled, incompletely sanitizes HTTP request headers, leading to 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. The risk increases if logs are forwarded to a centralized platform. The Common Vulnerability Scoring System (CVSS) score for this vulnerability is 6.2, indicating a MEDIUM severity level.

Who should care

Security teams and administrators responsible for foreman-mcp-server instances should be aware of this vulnerability. They should assess their exposure and take necessary actions to mitigate the risk. Red Hat users may find additional information in the provided errata and security advisories.

Technical summary

The foreman-mcp-server component has two logging mechanisms that can expose sensitive data. The first logs session identifiers as authentication credentials at an informational level. The second, when debug logging is enabled, does not properly sanitize HTTP request headers, leading to cleartext logging of sensitive information like authorization tokens and API keys. This can cause a confidentiality breach, especially if logs are forwarded to a centralized platform. The vulnerability has a CVSS score of 6.2 and a MEDIUM severity level.

Defensive priority

Apply patches or updates to foreman-mcp-server to fix the logging issue. Review and adjust logging configurations to minimize exposure of sensitive information.

Recommended defensive actions

Apply patches or updates to foreman-mcp-server to fix the logging issue.
Review and adjust logging configurations to minimize exposure of sensitive information.
Ensure logs are not forwarded to a centralized platform in plain text.
Consider implementing additional logging security measures, such as encryption or access controls.
Monitor for any suspicious activity related to foreman-mcp-server logs.
