RHSA-2025%3A9541 PUBLISHED CVSS 7.5 HIGH

A flaw was found in the `golang.org/x/oauth2/jws` package in the token parsing component. This vulnerability is made possible because of the use of `strings.Split(token, ".")` to split JWT tokens, which can lead to excessive memory consumption when processing maliciously crafted tokens with a large number of `.` characters. An attacker could exploit this functionality by sending numerous malformed tokens and can trigger memory exhaustion and a Denial of Service.
