A flaw was found in GO-JOSE. In affected versions, when parsing compact JWS or JWE input, Go JOSE could use excessive memory. 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. This issue could be exploied by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service.
