Go Jose · Go-Jose · CVE-2025-27144
**Name of the Vulnerable Software and Affected Versions**
Go JOSE versions 4.0.0 through 4.0.4
**Description**
The issue is related to excessive memory consumption when parsing compact JWS or JWE input. The code uses 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.
**Recommendations**
For versions 4.0.0 through 4.0.4, update to version 4.0.5 to fix the issue.
As a temporary workaround, applications could pre-validate that payloads passed to Go JOSE do not contain an excessive number of `.` characters.
