### Impact A malicious homeserver can craft a room or room structure such that the predecessors form a cycle. The matrix-js-sdk's `getRoomUpgradeHistory` function will infinitely recurse in this case, causing the code to hang. This method is public but also called by the 'leaveRoomChain()' method, so leaving a room will also trigger the bug. Even if the CVSS score would be 4.1 ([AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:N/A:L](https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:N/A:L&version=3.1)) we classify this as High severity issue. ### Patches This was patched in matrix-js-sdk 34.3.1. ### Workarounds Sanity check rooms before passing them to the matrix-js-sdk or avoid calling either `getRoomUpgradeHistory` or `leaveRoomChain`. ### References N/A.

# Attack Vector Then, let me briefly explain the reasons for the errors mentioned above: 1. The 'kubectl edit' command was used to patch the namespace, but this operation requires both 'get' and 'patch' permissions, hence the error. One should use methods like 'curl' to directly send a PATCH request; 2. The webhook does not intercept patch operations on 'kube-system' because 'kube-system' does not have an ownerReference. # Below are my detailed reproduction steps 1. Create a test cluster `kind create cluster --image=kindest/node:v1.24.15 --name=k8s` 2. Install the capsule `helm install capsule projectcapsule/capsule -n capsule-system --create-namespace` 3. Create a tenant ``` kubectl create -f - << EOF apiVersion: capsule.clastix.io/v1beta2 kind: Tenant metadata: name: tenant1 spec: owners: - name: alice kind: User EOF ``` 4. Create user alice ``` ./create-user.sh alice tenant1 capsule.clastix.io export KUBECONFIG=alice-tenant1.kubeconfig ``` 5. Patch kube-system (The first ...
