How to Fix CVE-2026-77564

To remediate this vulnerability, upgrade all affected Talos Linux dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/talos-systems/talos fixed: 1.14.0-alpha.0.0.20260513110206-76080416beee
Upgrade github.com/talos-systems/talos to 1.14.0-alpha.0.0.20260513110206-76080416beee
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/talos-systems/talos

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-77564, inspect your project dependencies for Talos Linux:

inspect dependencies for github.com/talos-systems/talos

Analyze the terminal output to locate any version of Talos Linux in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.14.0-alpha.0.0.20260513110206-76080416beee), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-312: Cleartext Storage of Sensitive Information, where the product stores sensitive information in cleartext within a resource that might be accessible to another control sphere. In Talos Linux, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary When generating a support bundle with `talosctl support` the credentials entered for private registries are included in the bundle. ### Details Within the generated support bundle, inside `resources/registryconfigs.cri.talos.dev.yaml` the `auth` field of the spec is retained. The same, potentially sensitive information is present within `etcfilespecs.files.talos.dev.yaml`. ### PoC Simply run `talosctl -n [...] support` on a cluster with a `RegistryAuthConfig` resource ### Impact The problem itself is minor, however, anyone who has ever uploaded a support.zip bundle on a github issue, slack thread or public forum could have potentially leaked their internal authentication parameters for a private registry. In most situations, if the network and credentials are set correctly, this should not be a problem. On the other hand, if the affected registry is publicly accessible, and the provided credentials have write access to it, this could lead to possibly serious consequences, from denial of service, to data loss and possibly existing tag hijacking leading to supply chain compromise, for the affected parties which were under the impression that the support bundle is redacted of sensitive information and thus can be shared publicly. ### Notes Talos 1.14+ by default encrypts the support bundle to the age recipients specified (defaulting to siderolabs GitHub org members), so the impact is even lower. ### Environment - Talos version: v1.13.0 - Kubernetes version: 1.35.3 - Platform: amd64
