Parameters

See plugin common configurations for configuration options available to all plugins.

allow_origins
string
default: *
Comma-separated string of origins to allow CORS.
If allow_credential is set to true, you can forcefully allow CORS on all origins by configuring the field to ** but sensitive data, such as authentication tokens or cookies, can get exposed to any malicious website.
You can also configure allow origins on a global scale using the plugin metadata, which configures the allow origins for all cors plugin instances. See the example for more details.
allow_methods
string
default: *
Comma-separated string of HTTP request methods to allow CORS.
If allow_credential is set to true, you can forcefully allow CORS on all methods by configuring the field to **, but a malicious actor can use HTTP methods, such as PUT or DELETE, to make unexpected modifications to shared resource and pose a security threat.
allow_headers
string
default: *
Comma-separated string of HTTP headers allowed in requests.
If allow_credential is set to true, you can forcefully allow CORS on all request headers by configuring the field to **, but it can potentially allow malicious headers to be sent to the server.
expose_headers
string
default: *
Comma-separated string of HTTP headers that should be made available in response to a cross-origin request.
If allow_credential is set to true, you can forcefully allow CORS on all response headers by configuring the field to **.
max_age
integer
default: 5
Maximum time in seconds for which the results of a preflight request can be cached. If the time is within this limit, the browser will check the cached result. To disable caching, set max_age to -1.
Note that the maximum value allowed is browser-dependent. See Access-Control-Max-Age for more details.
allow_credential
boolean
If true, allow requests to include credentials, such as cookies. According to CORS specification, when allow_credentials is set to true, you cannot use * for other CORS attributes.
To allow all origins, set the field to **. This can potentially allow sensitive user data, such as authentication tokens or cookies, to be exposed to malicious actors.
allow_origins_by_regex
array[string]
RegEx to match origins that allow CORS. When configured, only domains in this range will be allowed and any configuration in allow_origins will be ignored.
For example, ['.*\.test.com$'] can match all subdomains of test.com.
allow_origins_by_metadata
array[string]
Origins to enable CORS referenced from allow_origins set in the plugin metadata. For example, if allow_origins: {'EXAMPLE': 'https://example.com'} is set in the plugin metadata, then ['EXAMPLE'] can be used to allow CORS on the origin https://example.com.
timing_allow_origins
string
Comma-separated string of origins to allow to access the resource timing information. See Timing-Allow-Origin for more details.
timing_allow_origins_by_regex
array[string]
RegEx to match with origin for enabling access to the resource timing information. When configured, only domains matching the RegEx will be allowed and any configuration in timing_allow_origins will be ignored.
For example, ['.*\.test.com'] can match all subdomain of test.com.
