Changelog Entry

Description

[Concisely describe the changes made in this pull request, including any relevant motivation and impact (e.g., fixing a bug, adding a feature, or improving performance)]
Introduced a middleware to enhance the security of web applications by adding configurable HTTP security headers. These headers can be used to mitigate various common web vulnerabilities and improve the overall security posture of the application.

Added

Created middleware to configure certain security response headers on Open-WebUI. The following headers can be configured on the application
- Cache-Control : Controls browser caching policies. Configurable through the CACHE_CONTROL environment variable.
- Referrer-Policy : Configures the amount of referrer information sent during navigation. Configured through the REFERRER_POLICY environment variable.
- HTTP Strict Transport Security (HSTS) : Enforces HTTPS communication. Configurable via the HSTS environment variable.
- X-Frame-Options : Prevents Clickjacking. Configurable using the XFRAME_OPTIONS environment variable to specify options.
- X-Content-Type-Options : Prevents browsers from MIME-sniffing the content-type, forcing them to use the declared Content-Type header. Configurable using the XCONTENT_TYPE environment variable.
- X-Download-Options : Restricts browser behaviours when handling file downloads to prevent executable downloads from running. Configurable using the XDOWNLOAD_OPTIONS environment variable.
- X-Permitted-Cross-Domain-Policies : Limits permissible cross-domain policies to prevent unauthorized resource loading over domains. Configurable using the XPERMITTED_CROSS_DOMAIN_POLICIES environment variable.
