{"id":"CVE-2026-41452","summary":"Krayin CRM 2.2.4 Missing Authentication via install/api/admin-config-setup","details":"Krayin CRM 2.2.4 contains a missing authentication vulnerability in the installer middleware that allows unauthenticated remote attackers to overwrite the primary administrator account by sending a crafted HTTP POST request with the X-Requested-With: XMLHttpRequest header to bypass the CanInstall middleware redirect check. Attackers can supply arbitrary name, email, and password values to the admin-config-setup endpoint, which performs an unauthenticated updateOrInsert targeting the hardcoded administrator user ID, enabling full administrative access to all CRM data.","modified":"2026-08-07T11:51:03.652768944Z","published":"2026-08-03T15:43:05.347Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41452.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41452.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41452"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/krayin-crm-missing-authentication-via-install-api-admin-config-setup"},{"type":"PACKAGE","url":"https://github.com/krayin/laravel-crm"},{"type":"EVIDENCE","url":"https://jivasecurity.com/writeups/krayin-installer-bypass-account-takeover-cve-2026-41452"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/krayin/laravel-crm","events":[{"introduced":"0"},{"last_affected":"a282e7c3cf969bf10ccc8ebd636be502a58a5a9b"},{"introduced":"55b48fe86d7f196c32581ed80bb723cf0e18d44e"},{"last_affected":"55b48fe86d7f196c32581ed80bb723cf0e18d44e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.2.0"},{"introduced":"2.2.4"},{"last_affected":"2.2.4"}],"source":"AFFECTED_FIELD"}}],"versions":["2.2.4","v2.2.4","v2.2.0","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.2","v1.3.0","v2.0.1","v2.0.0","v2.0.0-BETA-1","v1.2.4","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41452.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
