CVE-2025-66506
Function identity.extractIssuerURL currently 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 with an (invalid) OIDC identity token in the payload containing many period characters, a call to
extractIssuerURLincurs 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. Relevant weakness: CWE-405: Asymmetric Resource Consumption (Amplification)Details
See identity.extractIssuerURL
