[I] bug: openid connect error when 2tabs are open [apisix]

emil191995 opened a new issue, #12360:
URL: https://github.com/apache/apisix/issues/12360

   ### Current Behavior
   
   When I have 2 tabs of my app that redirected to login page and I login in first app second automaticaly redirects to redirect uri and returns 500 error for that page
   
   ### Expected Behavior
   
   the second need to redirect my app page without 500 error
   
   I debuged and found the issue.
   in library openidc when first tab logs in it ends the session and when second comes to redirect_uri page it can not find the session state with the args in request uri cos it is already expired. so the way I solwed in my side is this
   `
           if err then
               if session then
                   session:close()
               end
               if err == "unauthorized request" then
                   if conf.unauth_action == "pass" then
                       return nil
                   end
                   return 401
               end
               if err == "state from argument does not match state restored from session" then
                   ngx.redirect(url)
                   return nil
               end
               core.log.error("OIDC authentication failed: ", err)
               return 500
           end`
   
   ### Error Logs
   
   _No response_
   
   ### Steps to Reproduce
   
   run apisix via docker image
   create route with plugin openid connect (I use keycloak as identity server)
   open 2 tabs of your app 
   login in first
   second redirects to redirect_uri
   
   ### Environment
   
   - APISIX version (run `apisix version`):
   - Operating system (run `uname -a`):
   - OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
   - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
   - APISIX Dashboard version, if relevant:
   - Plugin runner version, for issues related to plugin runners:
   - LuaRocks version, for installation issues (run `luarocks --version`):

   Yes, as I already explained in my previous comment: `due to lua-resty-openidc library being unable to handle the state of 2 or more concurrent login sessions from different tabs of the same browser (see https://github.com/zmartzone/lua-resty-openidc/issues/482)`.
   
   However, Apisix could help mitigating the effect of this issue as I suggested before: `what apisix openid-plugin can do in this case is to catch the error coming from the library and redirect the browser to the originally requested redirect_uri`

   I think this is a problem with the underlying library and has nothing to do with APISIX.

   Hi, I got the same issue as well, which I think is due to `lua-resty-openidc` library being unable to handle the state of 2 or more concurrent login sessions (see [lua-resty-openidc/issues/482](https://github.com/zmartzone/lua-resty-openidc/issues/482)).
   
   When this happens apisix logs show those errors:
   ```
   2025/06/23 15:04:32 [error] 51#51: *125572 [lua] openidc.lua:1106: authenticate(): state from argument: 0719c5fc06a12354487e0a531b31689c does not match state restored from session: 065c3b3ba7625fafe9e670355571841a, client: 10.42.0.3, server: _, request: "GET /callback?state=0719c5fc06a12354487e0a531b31689c&session_state=b0648d29-742a-4c7b-b0d6-6bb07dd0988f&iss=https%3A%2F%2Fportal.10.60.66.58.nip.io%3A31390%2Fauth%2Frealms%2Fmaster&code=1a4bc137-6c1c-4b2c-b92e-da93568e4a72.b0648d29-742a-4c7b-b0d6-6bb07dd0988f.3001bb42-4e21-4549-9201-b285c591db20 HTTP/1.1", host: "portal.10.60.66.58.nip.io:31390"

   ```
   
   The user instead gets a 500 error returned from /callback endpoint call:
   
   `GET https://portal.10.60.66.58.nip.io:31390/callback?state=0719c5fc06a12354487e0a531b31689c&session_state=b0648d29-742a-4c7b-b0d6-6bb07dd0988f&iss=https%3A%2F%2Fportal.10.60.66.58.nip.io%3A31390%2Fauth%2Frealms%2Fmaster&code=1a4bc137-6c1c-4b2c-b92e-da93568e4a72.b0648d29-742a-4c7b-b0d6-6bb07dd0988f.3001bb42-4e21-4549-9201-b285c591db20`
   
   However, the user is actually already logged in despite the error so redirecting the browser to a valid page is enough to bypass it.
   
   IMHO what apisix can do in this case is to catch the error coming from the library and redirect the browser to the originally requested redirect_uri; I believe in most of the cases this will work fine and transparently.
