As a result, in the face of a malicious request with an (invalid) OIDC identity token in the payload containing many period characters, a call to extractIssuerURL incurs allocations to the tune of O(n) bytes (where n stands for the length | [email protected] | 7.5 | 0.18% | 2025-12-04 | 2026-06-17 |
