{"id":"UBUNTU-CVE-2026-61637","details":"Icinga Web 2 is an open source monitoring web interface, framework and command-line interface. Prior to versions 2.12.7 and 2.13.1, an attacker can craft a URL that, once visited by an authenticated user (or one that is able to authenticate), allows to manipulate the backend to redirect the user to any location. For this to succeed, the victim's locale in Icinga Web must be different from en_US. This issue has been patched in versions 2.12.7 and 2.13.1.","modified":"2026-11-12T23:47:41.053821670Z","published":"2026-11-12T00:00:00Z","upstream":["CVE-2026-61637"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-61637"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-61637"},{"type":"REPORT","url":"https://github.com/Icinga/icingaweb2/security/advisories/GHSA-w7c2-xjv9-q8fv"}],"affected":[{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0-1ubuntu1","2.1.0-1ubuntu1.1","2.1.0-1ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.1.0-1ubuntu1.2","binary_name":"icingaweb2"},{"binary_name":"icingaweb2-module-monitoring","binary_version":"2.1.0-1ubuntu1.2"},{"binary_name":"php-icinga","binary_version":"2.1.0-1ubuntu1.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}},{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1-1","2.4.1-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.1-1ubuntu0.1","binary_name":"icingacli"},{"binary_version":"2.4.1-1ubuntu0.1","binary_name":"icingaweb2"},{"binary_name":"icingaweb2-common","binary_version":"2.4.1-1ubuntu0.1"},{"binary_version":"2.4.1-1ubuntu0.1","binary_name":"icingaweb2-module-monitoring"},{"binary_name":"php-icinga","binary_version":"2.4.1-1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}},{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.1-1","2.7.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"icingacli","binary_version":"2.7.3-1"},{"binary_name":"icingaweb2","binary_version":"2.7.3-1"},{"binary_name":"icingaweb2-common","binary_version":"2.7.3-1"},{"binary_name":"icingaweb2-module-monitoring","binary_version":"2.7.3-1"},{"binary_name":"php-icinga","binary_version":"2.7.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}},{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.2-2","2.9.3-1","2.9.4-1","2.9.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"icingacli","binary_version":"2.9.5-1"},{"binary_name":"icingaweb2","binary_version":"2.9.5-1"},{"binary_name":"icingaweb2-common","binary_version":"2.9.5-1"},{"binary_version":"2.9.5-1","binary_name":"icingaweb2-module-monitoring"},{"binary_name":"php-icinga","binary_version":"2.9.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}},{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.11.4-3","2.12.0-1","2.12.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"icingacli","binary_version":"2.12.1-1"},{"binary_name":"icingaweb2","binary_version":"2.12.1-1"},{"binary_name":"icingaweb2-common","binary_version":"2.12.1-1"},{"binary_name":"icingaweb2-module-monitoring","binary_version":"2.12.1-1"},{"binary_name":"php-icinga","binary_version":"2.12.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}},{"package":{"name":"icingaweb2","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/icingaweb2?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12.4-2","2.12.5-1","2.12.6-1"],"ecosystem_specific":{"binaries":[{"binary_name":"icingacli","binary_version":"2.12.6-1"},{"binary_name":"icingaweb2","binary_version":"2.12.6-1"},{"binary_version":"2.12.6-1","binary_name":"icingaweb2-common"},{"binary_version":"2.12.6-1","binary_name":"icingaweb2-module-monitoring"},{"binary_name":"php-icinga","binary_version":"2.12.6-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-61637.json"}}],"schema_version":"1.9.2","severity":[{"type":"Ubuntu","score":"medium"}]}
