{"id":"CVE-2026-37233","details":"FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eq_xapp_ric_gen_id() in src/ric/iApp/xapp_ric_id.c compares m0-\u003exapp_id against itself (m0-\u003exapp_id) instead of the other argument (m1-\u003exapp_id), effectively ignoring the xApp identity dimension. A malicious xApp connected to the iApp (port 36422) can delete any other xApp's subscriptions by sending an E42_RIC_SUBSCRIPTION_DELETE_REQUEST with a matching ric_gen_id. This breaks multi-tenant isolation in any deployment with multiple xApps sharing the same RIC.","modified":"2026-07-24T03:57:02.917265399Z","published":"2026-06-01T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37233.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/37xxx/CVE-2026-37233.json"},{"type":"ADVISORY","url":"https://github.com/MinamiKotor1/oran-security-advisories-zhongnan-luo/blob/main/advisories/CVE-2026-37233.md"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-37233"},{"type":"PACKAGE","url":"https://gitlab.eurecom.fr/mosaic5g/flexric"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.eurecom.fr/mosaic5g/flexric","events":[{"introduced":"1f04cc558ebc8da9de6a620762bc02f5db4ecb4a"},{"last_affected":"1f04cc558ebc8da9de6a620762bc02f5db4ecb4a"}],"database_specific":{"extracted_events":[{"introduced":"2.0.0"},{"last_affected":"2.0.0"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:mosaic5g:flexric:2.0.0:*:*:*:*:*:*:*"}}],"versions":["2.0.0","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-37233.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
