Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Race condition

EUVDB-ID: #VU111976

Risk: Low

CVSSv4.0: 0.6 [CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-32441

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists because when using the `Rack::Session::Pool` middleware, simultaneous rack requests can restore a deleted rack session. A remote user can trigger a long running request (within that same session) adjacent to the user logging out, in order to retain illicit access even after a user has attempted to logout.

Mitigation

Update the affected package rubygem-rack to the latest version.
