{"id":"CVE-2026-55550","summary":"NextCRM has RBAC Bypass in MCP Product Tools that Allows Low-Privileged Users to Modify the CRM Product Catalog","details":"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.","aliases":["GHSA-wv63-cq38-qg58"],"modified":"2026-07-23T03:56:39.902462394Z","published":"2026-07-20T21:02:16.513Z","database_specific":{"cwe_ids":["CWE-269","CWE-284","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55550.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55550.json"},{"type":"ADVISORY","url":"https://github.com/pdovhomilja/nextcrm-app/security/advisories/GHSA-wv63-cq38-qg58"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55550"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pdovhomilja/nextcrm-app","events":[{"introduced":"6f11b4d58383af52dffd02ab491813cea9667c9f"},{"last_affected":"6f11b4d58383af52dffd02ab491813cea9667c9f"}],"database_specific":{"extracted_events":[{"introduced":"= 0.12.1"},{"last_affected":"= 0.12.1"}],"source":"AFFECTED_FIELD"}}],"versions":["= 0.12.1","v0.12.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55550.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L"}]}
