How to Fix CVE-2026-53489

To remediate this vulnerability, upgrade all affected Github.com/containerd/containerd/v2 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/containerd/containerd/v2 fixed: 2.1.9
Upgrade github.com/containerd/containerd/v2 to 2.1.9
github.com/containerd/containerd/v2 fixed: 2.2.5
Upgrade github.com/containerd/containerd/v2 to 2.2.5
github.com/containerd/containerd/v2 fixed: 2.3.2
Upgrade github.com/containerd/containerd/v2 to 2.3.2
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/containerd/containerd/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-53489, inspect your project dependencies for Github.com/containerd/containerd/v2:

inspect dependencies for github.com/containerd/containerd/v2

Analyze the terminal output to locate any version of Github.com/containerd/containerd/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.9), 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-61: UNIX Symbolic Link (Symlink) Following, where the product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. this could allow an attacker to cause the product to operate on unauthorized files. In Github.com/containerd/containerd/v2, 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

### Impact A bug was found in containerd where the CRI plugin restores `container.log` from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via `kubectl logs`. ### Patches This bug has been fixed in the following containerd versions: * 2.3.2 * 2.2.5 * 2.1.9 Users should update to these versions to resolve the issue. ### Workarounds Ensure that only trusted images and checkpoints are used. ### Credits The containerd project would like to thank @gouldnicholas and @davidrxchester, Yuming Zhang and Song Li of Zhejiang University, Sangwon Ryu (@sangwon090), Henry Beberman (@hbeberman) of Microsoft, the GKE Security Team using Gemini, Anthropic Research, in collaboration with Claude, Robert Prast (@robertprast), Kyle Elliott (@kyle-elliott-tob) of Trail of Bits, and Zhenchen Wang (@Plucky923), who independently discovered and responsibly disclosed this issue in accordance with the [containerd security policy](https://github.com/containerd/project/blob/main/SECURITY.md). ### For more information If you have any questions or comments about this advisory: * Open an issue in [containerd](https://github.com/containerd/containerd/issues/new/choose) * Email us at [security@containerd.io](mailto:security@containerd.io) To report a security issue in containerd: * [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new) * Email us at [security@containerd.io](mailto:security@containerd.io)
