PUT requets returning 403

Hello,

Over the last couple of days I've had a couple of app services start returning 403 forbidden errors for PUT requests. These have been running quite nicely for months without any issues - it's just suddenly started with no changes having been made. POST requests work fine. One of the apps was using MSAL for auth, however the other one is just using the standard code in the URL.

Thanks

@Gareth Walker Apology for the delay and any inconvenience with this issue. The product team has updated the code to fix this issue: https://github.com/Azure/azure-functions-host/pull/7270 and the fix will start deploying soon.

You can watch the app service announcement repo to receive notification about new version releases: https://github.com/Azure/app-service-announcements/issues

The workaround would be to pin it to version 3.0.15406: https://learn.microsoft.com/en-us/azure/azure-functions/functions-app-settings#functions_extension_version
