Description
A vulnerability has been found in openstatusHQ openstatus up to f04c827112f30a11d571ebdad3892826034d6265. Affected by this vulnerability is an unknown functionality of the file apps/status-page/src/lib/proxy/resolve-custom-domain-rewrite.ts. The manipulation leads to server-side request forgery. The attack may be initiated remotely. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The identifier of the patch is 86f370c9c20074c3c3fdec53a359874b8e670fd4. It is suggested to install a patch to address this issue. This issue got fixed with a silent patch.
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-2026-90486 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-2026-90486 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-2026-90486. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
