{"id":"CVE-2026-70557","summary":"diboot-core Authenticated Arbitrary Field Read via loadRelatedData Discloses Password Hashes and Salts","details":"diboot-core's POST /common/load-related-data endpoint resolves caller-supplied field names to any @TableField column of any entity and returns those values for all rows, with no field or entity allowlist. The only guard, relatedDataSecurityCheck(), returns true unconditionally, so any authenticated user (including a zero-role account) can read @JsonIgnore-annotated secret fields such as IamAccount.authSecret and IamAccount.secretSalt for every account, or arbitrary secret fields of any other entity. Shiro's two-iteration MD5 with an 8-character salt is trivially crackable offline, so the disclosed admin password hashes convert to full administrative takeover. The endpoint is not example code; the official diboot-admin-ui frontend requires it, so deployments following the vendor's recommended integration expose it. The mechanism was renamed relatedData* to attachMore* on the development branch, but attachMoreSecurityCheck() also returns true unconditionally.","modified":"2026-08-09T03:30:36.097226175Z","published":"2026-08-06T19:16:18.724Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70557.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70557.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70557"},{"type":"PACKAGE","url":"https://github.com/dibo-software/diboot"},{"type":"ARTICLE","url":"https://github.com/dibo-software/diboot/issues/104"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dibo-software/diboot","events":[{"introduced":"0"},{"last_affected":"4b37153f6766d60aedc90ff32731f6f52f0ba481"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"3.9.0"}]}}],"versions":["v3.9.0","v3.8.0","v3.7.0","v3.6.0","v3.5.0","v3.4.0","v3.3.0","v3.2.0","v3.1.0","v3.0.0","v2.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-70557.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
