How to Fix CVE-2025-27144

To remediate this vulnerability, upgrade all affected Github.com/go jose/go jose/v4 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/go-jose/go-jose/v4 fixed: 4.0.5 
Upgrade github.com/go-jose/go-jose/v4 to 4.0.5
github.com/go-jose/go-jose/v3 fixed: 3.0.4 
Upgrade github.com/go-jose/go-jose/v3 to 3.0.4
github.com/go-jose/go-jose fixed: 3.0.4 
Upgrade github.com/go-jose/go-jose to 3.0.4
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/go-jose/go-jose/v4

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-27144, inspect your project dependencies for Github.com/go jose/go jose/v4:

inspect dependencies for github.com/go-jose/go-jose/v4

Analyze the terminal output to locate any version of Github.com/go jose/go jose/v4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.5), 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/go jose/go jose/v4, 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 When parsing compact JWS or JWE input, go-jose could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of '.' characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service. ### Patches Version 4.0.5 fixes this issue ### Workarounds Applications could pre-validate payloads passed to go-jose do not contain an excessive number of '.' characters. ### References This is the same sort of issue as in the golang.org/x/oauth2/jws package as CVE-2025-22868 and Go issue https://go.dev/issue/71490.
