CVE-2026-70557
MEDIUMCVE-2026-70557 is a medium-severity (CVSS 6.5) CWE-639 vulnerability. O3 Security confirms whether CVE-2026-70557 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-70557 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-70557 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-70557. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
