A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 25.10 - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: Several security issues were fixed in Rack. Software Description: - ruby-rack: modular Ruby webserver interface Details: Minh Pham Quang discovered that Rack did not correctly handle parsing certain paths, which could lead to a path traversal attack. An attacker could possibly use this issue to leak sensitive information. (CVE-2026-22860) Ali Firas discovered that Rack did not correctly sanitize certain inputs. An attacker could possibly use this issue to execute arbitrary code. (CVE-2026-25500)
