CVE-2023-48713 WRITEUP MEDIUM WRITEUP
Knative Serving < 1.10.5 and >=0 <0.39.0 - Denial of Service via /metrics Endpoint
Knative Serving builds on Kubernetes to support deploying and serving of applications and functions as serverless containers. An attacker who controls a pod to a degree where they can control the responses from the /metrics endpoint can cause Denial-of-Service of the autoscaler from an unbound memory allocation bug. This is a DoS vulnerability, where a non-privileged Knative user can cause a DoS for the cluster. This issue has been patched in version 0.39.0.

CVE-2024-37904 WRITEUP MEDIUM WRITEUP
Minder < 0.0.52 - Denial of Service via Git Repository Clone
Minder is an open source Software Supply Chain Security Platform. Minder's Git provider is vulnerable to a denial of service from a maliciously configured GitHub repository. The Git provider clones users repositories using the `github.com/go-git/go-git/v5` library on lines `L55-L89`. The Git provider does the following on the lines `L56-L62`. First, it sets the `CloneOptions`, specifying the url, the depth etc. It then validates the options. It then sets up an in-memory filesystem, to which it clones and Finally, it clones the repository. The `(g *Git) Clone()` method is vulnerable to a DoS attack: A Minder user can instruct Minder to clone a large repository which will exhaust memory and crash the Minder server. The root cause of this vulnerability is a combination of the following conditions: 1. Users can control the Git URL which Minder clones, 2. Minder does not enforce a size limit to the repository, 3. Minder clones the entire repository into memory. This issue has been addressed in commit `7979b43` which has been included in release version v0.0.52. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2024-27093 WRITEUP MEDIUM WRITEUP
Minder < 0.0.31 - Denial of Service via Invalid Repository Upstream ID
Minder is a Software Supply Chain Security Platform. In version 0.0.31 and earlier, it is possible for an attacker to register a repository with a invalid or differing upstream ID, which causes Minder to report the repository as registered, but not remediate any future changes which conflict with policy (because the webhooks for the repo do not match any known repository in the database). When attempting to register a repo with a different repo ID, the registered provider must have admin on the named repo, or a 404 error will result. Similarly, if the stored provider token does not have repo access, then the remediations will not apply successfully. Lastly, it appears that reconciliation actions do not execute against repos with this type of mismatch. This appears to primarily be a potential denial-of-service vulnerability. This vulnerability is patched in version 0.20240226.1425+ref.53868a8.
