{"id":"CVE-2026-63000","summary":"REDAXO: Missing CSRF Protection on Package Update Action Allows Forced Addon Updates","details":"REDAXO is a PHP-based content management system. Prior to 5.21.2, rex_api_install_package_update in redaxo/src/addons/install/lib/api/api_package_update.php inherits the false default from rex_api_function::requiresCsrfProtection() instead of requiring a CSRF token. An unauthenticated attacker can cause a logged-in administrator's browser to request a selected package update from the configured REDAXO package server, changing installed addon code or disrupting the site without the administrator's intent. This issue is fixed in version 5.21.2.","aliases":["GHSA-m8r3-22v6-g877"],"modified":"2026-09-30T03:30:25.342873349Z","published":"2026-09-23T14:08:42.402Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63000.json"},"references":[{"type":"WEB","url":"https://github.com/redaxo/core/releases/tag/5.21.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63000.json"},{"type":"ADVISORY","url":"https://github.com/redaxo/core/security/advisories/GHSA-m8r3-22v6-g877"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63000"},{"type":"FIX","url":"https://github.com/redaxo/core/commit/a13abbffbad4fdea46a4edc86cdba3335ca9e8f3"},{"type":"FIX","url":"https://github.com/redaxo/core/pull/6579"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/redaxo/core","events":[{"introduced":"0"},{"fixed":"a13abbffbad4fdea46a4edc86cdba3335ca9e8f3"},{"fixed":"31d61c6a460b6c8daf09baa75d6477fa3a93a68b"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.21.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["5.21.1","5.21.0","5.21.0-beta1","5.20.2","5.20.1","5.20.0","5.19.0","5.18.3","5.18.2","5.18.1","5.18.0","5.17.1","5.17.0","5.16.1","5.16.0","5.16.0-beta1","5.15.0","5.15.0-beta1","5.14.1","5.14.0","5.14.0-beta2","5.14.0-beta1","5.13.2","5.13.1","5.13.0","5.13.0-beta2","5.13.0-beta1","5.12.0","5.12.0-beta3","5.12.0-beta2","5.12.0-beta1","5.11.0","5.11.0-beta1","5.10.0","5.10.0-beta2","5.10.0-beta1","5.9.0","5.9.0-beta2","5.9.0-beta1","5.8.0","5.8.0-beta1","5.7.0","5.7.0-beta3","5.7.0-beta2","5.7.0-beta1","5.6.1","5.6.0","5.6.0-beta1","5.5.1","5.5.0","5.5.0-beta1","5.4.0","5.4.0-beta2","5.4.0-beta1","5.3.0","5.2.0","5.2.0-beta1","5.1.0","5.0.1","5.0.0","5.0.0-rc","5.0.0-beta2","5.0.0-beta1","5.0.0-alpha7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63000.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:H/A:L"}]}
