| CVE-2026-35206 | Helm is a package manager for Charts for Kubernetes. In Helm versions <=3.20.1 and <=4.1.3, a specially crafted Chart will cause helm pull --untar [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the --destination and --untardir flags), rather than the expected output directory suffixed by the chart's name. This vulnerability is fixed in 3.20.2 and 4.1.4. | [email protected] | 4.8 | 0.01% | 2026-04-09 | 2026-04-16 |
| CVE-2026-35205 | Helm is a package manager for Charts for Kubernetes. From 4.0.0 to 4.1.3, Helm will install plugins missing provenance (.prov file) when signature verification is required. This vulnerability is fixed in 4.1.4. | [email protected] | 8.4 | 0.01% | 2026-04-09 | 2026-04-17 |
| CVE-2026-35204 | Helm is a package manager for Charts for Kubernetes. From 4.0.0 to 4.1.3, a specially crafted Helm plugin, when installed or updated, will cause Helm to write the contents of the plugin to an arbitrary filesystem location. To prevent this, validate that the plugin.yaml of the Helm plugin does not include a version: field containing POSIX dot-dot path separators ie. "/../".

| CVE-2025-55199 | Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero. | [email protected] | 6.5 | 0.03% | 2025-08-14 | 2025-08-21 |
| CVE-2025-55198 | Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, when parsing Chart.yaml and index.yaml files, an improper validation of type error can lead to a panic. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring YAML files are formatted as Helm expects prior to processing them with Helm. | [email protected] | 6.5 | 0.02% | 2025-08-14 | 2025-08-21 |
| CVE-2025-53547 | Helm is a package manager for Charts for Kubernetes. Prior to 3.18.4, a specially crafted Chart.yaml file along with a specially linked Chart.lock file can lead to local code execution when dependencies are updated. Fields in a Chart.yaml file, that are carried over to a Chart.lock file when dependencies are updated and this file is written, can be crafted in a way that can cause execution if that same content were in a file that is executed (e.g., a bash.rc file or shell script).

| CVE-2025-32387 | Helm is a package manager for Charts for Kubernetes. A JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow.

| CVE-2025-32386 | Helm is a tool for managing Charts. A chart archive file can be crafted in a manner where it expands to be significantly larger uncompressed than compressed (e.g., >800x difference). When Helm loads this specially crafted chart, memory can be exhausted causing the application to terminate.

| CVE-2019-25210 | An issue was discovered in Cloud Native Computing Foundation (CNCF) Helm through 3.13.3. It displays values of secrets when the --dry-run flag is used. This is a security concern in some use cases, such as a --dry-run call by a CI/CD tool. NOTE: the vendor's position is that this behavior was introduced intentionally, and cannot be removed without breaking backwards compatibility (some users may be relying on these values). Also, it is not the Helm Project's responsibility if a user decides to u | [email protected] | 6.5 | 0.22% | 2024-03-03 | 2025-02-11 |
| CVE-2024-26147 | Helm is a package manager for Charts for Kubernetes. Versions prior to 3.14.2 contain an uninitialized variable vulnerability when Helm parses index and plugin yaml files missing expected content. When either an `index.yaml` file or a plugins `plugin.yaml` file were missing all metadata a panic would occur in Helm. In the Helm SDK, this is found when using the `LoadIndexFile` or `DownloadIndexFile` functions in the `repo` package or the `LoadDir` function in the `plugin` package.

| CVE-2024-25620 | Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources. When either the Helm client or SDK is used to save a chart whose name within the `Chart.yaml` file includes a relative path change, the chart would be saved outside its expected directory based on the changes in the relative path. The validation and linting did not detect the path changes in the name. This issue has been resolved in Helm v3.14.1.

The function is able to accept a hostname and return an IP address for that hostname. To get the IP address the function performs a DNS lookup.

| CVE-2022-23526 | Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to NULL Pointer Dereference in the_chartutil_ package that can cause a segmentation violation. The _chartutil_ package contains a parser that loads a JSON Schema validation file. For example, the Helm client when rendering a chart will validate its values with the schema file. The _chartutil_ package parses the schema file and loads it into structures Go can work with. Some schema files | [email protected] | 5.3 | 0.06% | 2022-12-15 | 2024-11-21 |

| CVE-2022-23524 | Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to Uncontrolled Resource Consumption, resulting in Denial of Service. Input to functions in the _strvals_ package can cause a stack overflow. In Go, a stack overflow cannot be recovered from. Applications that use functions from the _strvals_ package in the Helm SDK can have a Denial of Service attack when they use this package and it panics. This issue has been patched in 3.10.3.

Helm controller is tightly integrated with the Helm SDK. A vulnerability found in the Helm SDK that affects flux2 v0.0.17 until v0.32.0 and helm-controller v0.0.4 until v0.23.0 allows for specific data inputs to cause high memory consumption.

| CVE-2022-36055 | 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.

| CVE-2020-15187 | In Helm before versions 2.16.11 and 3.3.2, a Helm plugin can contain duplicates of the same entry, with the last one always used. If a plugin is compromised, this lowers the level of access that an attacker needs to modify a plugin's install hooks, causing a local execution attack. To perform this attack, an attacker must have write access to the git repository or plugin archive (.tgz) while being downloaded (which can occur during a MITM attack on a non-SSL connection).
