Prior to \n5.2.2 and 4.5.2, the function parse.ParseUnverified splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request whose Authorization header consists of Bearer  followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. This issue is fixed in 5.2.2 and 4.5.2.\n\ud83d\udccf Published: 2025-03-21T21:42:01.382Z\n\ud83d\udccf Modified: 2025-03-21T21:42:01.382Z\n\ud83d\udd17 References:\n1. https://github.com/golang-jwt/jwt/security/advisories/GHSA-mh63-6h87-95cp\n2. https://github.com/golang-jwt/jwt/commit/0951d184286dece21f73c85673fd308786ffe9c3", "creation_timestamp": "2025-03-21T22:21:05.000000Z"}
