While the vulnerability allows for a denial of service (DoS) attack, it requires an attacker to craft a malicious JWE Token with a high compression ratio. This specific condition limits the practical exploitability of the vulnerability to some extent, as it demands a more sophisticated attack approach than common vulnerabilities. Nonetheless, if exploited, the vulnerability can lead to significant memory exhaustion and increased server processing time, impacting the overall performance and availability of the affected system.",
