{"id":"CVE-2026-55550","state":"PUBLISHED","title":"NextCRM has RBAC Bypass in MCP Product Tools that Allows Low-Privileged Users to Modify the CRM Product Catalog","description":"NextCRM is open-source customer relationship management (CRM) software. The CRM product catalog is an organization-wide business object. Normal application server actions restrict product creation, update, and deletion to `manager` and `admin` roles. However, in version 0.12.1, the MCP product tools expose the same write operations through `/api/mcp/mcp` using user-generated Bearer tokens and do not enforce role checks. Any authenticated low-privileged user who can generate an MCP API token can create, modify, archive, or soft-delete products in the shared CRM product catalog. Version 0.12.3 contains a fix.","publishedAt":"2026-07-20T21:02:16.513Z","updatedAt":"2026-07-20T21:41:29.884Z","severity":{"score":7.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["pdovhomilja nextcrm-app"],"affected":[{"vendor":"pdovhomilja","product":"nextcrm-app","versions":[{"version":"= 0.12.1","status":"affected"}]}],"references":["https://github.com/pdovhomilja/nextcrm-app/security/advisories/GHSA-wv63-cq38-qg58"],"weaknesses":["CWE-269","CWE-284","CWE-862"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/55xxx/CVE-2026-55550.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-55550","state":"PUBLISHED","datePublished":"2026-07-20T21:02:16.513Z","dateUpdated":"2026-07-20T21:41:29.884Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-16T23:01:04.075Z"},"containers":{"cna":{"title":"NextCRM has RBAC Bypass in MCP Product Tools that Allows Low-Privileged Users to Modify the CRM Product Catalog","descriptions":[{"lang":"en","value":"NextCRM is open-source customer relationship management (CRM) software.
