How to Fix CVE-2022-28948

To remediate this vulnerability, upgrade all affected Gopkg.in/yaml.v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

gopkg.in/yaml.v3 fixed: 3.0.1 
Upgrade gopkg.in/yaml.v3 to 3.0.1
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 gopkg.in/yaml.v3

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-28948, inspect your project dependencies for Gopkg.in/yaml.v3:

inspect dependencies for gopkg.in/yaml.v3

Analyze the terminal output to locate any version of Gopkg.in/yaml.v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.1), 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Gopkg.in/yaml.v3, 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

An issue in the Unmarshal function in Go-Yaml v3 can cause a program to panic when attempting to deserialize invalid input.
