In versions 8.2.6.4 and prior, PUT /smon/check (app/routes/smon/routes.py:117-138) gates only on roxywi_common.check_user_group_for_flask() — which validates that the caller has some group, not that the target check_id belongs to it. The downstream SQL update functions update_smon, update_smonHttp, update_smonTcp, update_smonPing, update_smonDns (app/modules/db/smon.py:515-562) all execute WHERE smon_id = ? with no user_group filter. The DELETE path is correctly filtered (app/modules/db/smon.py:319-327 does WHERE id = ? AND user_group = ?), demonstrating that the maintainers know the right pattern but did not apply it on UPDATE. Therefore any authenticated user can iterate over smon_id values and silently rewrite any other tenant's HTTP / TCP / Ping / DNS monitoring check. At time of publication, there are no publicly available patches."}],"source":{"advisory":"GHSA-856h-mvm2-2h2x","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-856h-mvm2-2h2x","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-10T16:24:46.905909Z","id":"CVE-2026-45550","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-10T16:31:33.373Z"}}]}}
