Description
An attacker can pass a malicious malformed token which causes unexpected memory to be consumed during parsing.
Security Summary
CVE-2025-22868 is a vulnerability in the Go programming language that allows an attacker to pass a malicious malformed token, resulting in unexpected memory consumption during parsing. This issue, associated with CWE-1286, carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating a high-severity denial-of-service risk with no impact on confidentiality or integrity.
