CVE-2026-12112

Опубликовано: 23 июн. 2026
Источник: redhat
CVSS3: 7.8
EPSS Низкий

Описание

A flaw was found in the foreman-mcp-server. A session management vulnerability in the MCP Server allows unauthenticated attackers to hijack active administrative sessions due to an improper cache of authenticated client connections, by trusting a non-secret session ID without re-validating authentication tokens and by logging all newly created session IDs to standard logs. This issue can result in privilege escalation and infrastructure-wide code execution.

Отчет

Success exploitation leads to privilege escalation, granting an unauthenticated attacker the ability to execute infrastructure-wide code execution. Due to this reason, this flaw has been rated with an important severity.

Меры по смягчению последствий

Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
