Session cookie issue in Apple's Webkit

Dears,

We are facing some issue in ios 18.4.1. Recently some of our end users who updated their ios devices to 18.4.1 have experienced random 403 errors in runtime. as per our analysis, We identified that these errors are associated with "CSRF token mismatch".

After successful login, the user's CSRF token is causing issue and it was changed in runtime, this causes the cookie mismatch, and the users is getting 403 errors, and the user session is getting invalid suddenly.

let me know if anyone facing the same issue in ios 18.4.1 and let me know Is there any workaround for this issue.

Thanks.
