How to Fix CVE-2026-46599

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

golang.org/x/image fixed: 0.41.0 
Upgrade golang.org/x/image to 0.41.0
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 golang.org/x/image

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-46599, inspect your project dependencies for Golang.org/x/image:

inspect dependencies for golang.org/x/image

Analyze the terminal output to locate any version of Golang.org/x/image in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.41.0), 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-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Golang.org/x/image, 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

The TIFF decoder does not place a limit on the size of PackBits-compressed data. A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height and encoded size) to make the decoder decode large amounts of compressed data.
