How to Fix CVE-2024-24786

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

google.golang.org/protobuf fixed: 1.33.0 
Upgrade google.golang.org/protobuf to 1.33.0
google.golang.org/protobuf/encoding/protojson fixed: 1.33.0 
Upgrade google.golang.org/protobuf/encoding/protojson to 1.33.0
google.golang.org/protobuf/internal/encoding/json fixed: 1.33.0 
Upgrade google.golang.org/protobuf/internal/encoding/json to 1.33.0
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 google.golang.org/protobuf

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-24786, inspect your project dependencies for Google.golang.org/protobuf:

inspect dependencies for google.golang.org/protobuf

Analyze the terminal output to locate any version of Google.golang.org/protobuf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.33.0), 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-835: Loop with Unreachable Exit Condition ('Infinite Loop'), where the product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. In Google.golang.org/protobuf, 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 protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.
