Attackers can send a POST request to the team-invitations route specifying the admin role for a second account, bypassing privilege-level validation in InviteTeamMember, causing the second account upon invitation acceptance to be attached to the team with full admin-level create, read, update, and delete access over all team-scoped data.","publishedAt":"2026-09-29T19:13:13.767Z","updatedAt":"2026-09-30T19:27:52.083Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Liberu Software Liberu CRM"],"affected":[{"vendor":"Liberu Software","product":"Liberu CRM","packageURL":"pkg:github/liberusoftware/crm-laravel","defaultStatus":"unaffected","versions":[{"version":"0.9.1","status":"affected","lessThan":"10.0.0","versionType":"semver"}],"repo":"https://github.com/liberusoftware/crm-laravel"}],"references":["https://github.com/liberusoftware/crm-laravel/issues/708","https://github.com/liberusoftware/crm-laravel/releases/tag/v10.0.0","https://github.com/liberusoftware/crm-laravel/commit/0846d067ae2e9c437e8555e54a4ec6517927b3d4","https://www.vulncheck.com/advisories/liberu-crm-broken-access-control-via-teampolicy-addteammember"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61519.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61519","state":"PUBLISHED","datePublished":"2026-09-29T19:13:13.767Z","dateUpdated":"2026-09-30T19:27:52.083Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-07-10T15:43:36.628Z"},"containers":{"cna":{"title":"Liberu CRM 0.9.1 < 10.0.0 Broken Access Control via TeamPolicy::addTeamMember()","descriptions":[{"lang":"en","value":"Liberu CRM 0.9.1 before 10.0.0 contains a broken access control vulnerability that allows any user holding a pending team invitation to invite additional attacker-controlled accounts with elevated privileges by exploiting a flawed authorization predicate in TeamPolicy::addTeamMember() that grants invitation rights based solely on the existence of a pending invitation email match.
