Description
Sealos is a Cloud Operating System designed for managing cloud-native applications. In version 4.2.0 and prior, there is a permission flaw in the Sealos billing system, which allows users to control the recharge resource account sealos[.] io/v1/Payment, resulting in the ability to recharge any amount of 1 renminbi (RMB). The charging interface may expose resource information. The namespace of this custom resource would be user's control and may have permission to correct it. It is not clear whether a fix exists.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/labring/sealos. 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 github.com/labring/sealos has shipped for CVE-2023-36815 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-2023-36815 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-2023-36815. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
