High [CVE-2026-12112] Active Session Hijacking via Insecure Session State Reuse
CVE-2026-12112Source published Source updated
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. Due to this reason, this flaw has been rated with an important severity. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-287. Affected Red Hat products: Red Hat Satellite 6.18; Red Hat Satellite 6.19. Red Hat fixing advisory: RHSA-2026:28405, RHSA-2026:28438.
