Flux CLI allows users to deploy Flux components into a Kubernetes cluster via command-line. The vulnerability allows other applications to replace the Flux deployment information with arbitrary content which is deployed into the target Kubernetes cluster instead. The vulnerability is due to the improper handling of user-supplied input, which results in a path traversal that can be controlled by the attacker. ### Impact Users sharing the same shell between other applications and the Flux CLI commands could be affected by this vulnerability. In some scenarios no errors may be presented, which may cause end users not to realise that something is amiss. ### Workarounds A safe workaround is to execute Flux CLI in ephemeral and isolated shell environments, which can ensure no persistent values exist from previous processes. However, upgrading to the latest version of the CLI is still the recommended mitigation strategy. ### Credits The Flux engineering team found and patched this vulne...

A vulnerability was found in the search-api container in Red Hat Advanced Cluster Management for Kubernetes when a query in the search filter gets parsed by the backend. This flaw allows an attacker to craft specific strings containing special characters that lead to crashing the pod and affects system availability while restarting.

A flaw was found in the Red Hat Advanced Cluster Security for Kubernetes. Notifier secrets were not properly sanitized in the GraphQL API. This flaw allows authenticated ACS users to retrieve Notifiers from the GraphQL API, revealing secrets that can escalate their privileges.

Weave GitOps Enterprise before 0.9.0-rc.5 has a cross-site scripting (XSS) bug allowing a malicious user to inject a javascript: link in the UI. When clicked by a victim user, the script will execute with the victim's permission. The exposure appears in Weave GitOps Enterprise UI via a GitopsCluster dashboard link. An annotation can be added to a GitopsCluster custom resource.

Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources. Fuzz testing, provided by the CNCF, identified input to functions in the _strvals_ package that can cause an out of memory panic. The _strvals_ package contains a parser that turns strings in to Go structures. The _strvals_ package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing an out of memory panic. Applications that use the _strvals_ package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from. The Helm Client will panic with input to `--set`, `--set-string`, and other value setting flags that causes an out of memory panic. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been resolved in 3.9.4. SDK users can validate strings supplied by users won't create large a...
