CVE-2026-44424
MEDIUMCVE-2026-44424 is a medium-severity (CVSS 6.5) vulnerability in github.com/shellhub-io/shellhub. O3 Security confirms whether CVE-2026-44424 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
ShellHub: Cross-tenant IDOR in `GET /api/devices/:uid` discloses device data of any namespace
Blast Radius
github.com/shellhub-io/shellhubReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/devices/:uid returns the full device object whenever the caller is authenticated, without verifying that the device belongs to the caller's namespace (tenant). Any authenticated user (JWT or API Key) who knows or can guess a device UID can read device metadata from any other namespace. This vulnerability is fixed in 0.24.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/shellhub-io/shellhub. 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.
Fix
Update github.com/shellhub-io/shellhub to 0.24.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44424 is resolved across your whole dependency graph.
Workarounds
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-2026-44424 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-2026-44424. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
