Functions

func BodyLimit 

func BodyLimit(maxBytes int64) func(http.Handler) http.Handler

BodyLimit limits the maximum size of request bodies. If maxBytes is 0, DefaultMaxBodySize is used.

func CORS 

func CORS(cfg *config.CORSConfig) func(http.Handler) http.Handler

CORS adds CORS headers based on configuration. Deprecated: Use CORSWithEnvironment for production-safe CORS handling.

func CORSWithEnvironment added in v0.1.2 

func CORSWithEnvironment(cfg *config.CORSConfig, appEnv string) func(http.Handler) http.Handler

CORSWithEnvironment creates a CORS middleware that enforces environment-specific rules. In production (APP_ENV=production), wildcard "*" origins are rejected at config validation. This function adds runtime enforcement as a defense-in-depth measure.

func CSRF 

func CSRF(cfg CSRFConfig) func(http.Handler) http.Handler

CSRF returns a middleware that validates CSRF tokens using Double Submit Cookie pattern. It compares the token in the cookie with the token sent in the X-CSRF-Token header. Safe methods (GET, HEAD, OPTIONS) are exempt from CSRF validation.

func CSRFOptional 

func CSRFOptional(cfg CSRFConfig) func(http.Handler) http.Handler

CSRFOptional is like CSRF but only validates if a CSRF cookie is present. Useful for endpoints that can be called both with and without cookies.

func CampaignRoleResolver added in v0.1.3 

func CampaignRoleResolver(roleQuerier CampaignRoleQuerier) func(http.Handler) http.Handler

CampaignRoleResolver creates a middleware that resolves the user's campaign role from the database and stores it in the request context. It uses the {id} URL parameter for the campaign ID. Admin users bypass the DB query entirely.

func ClearCSRFTokenCookie 

func ClearCSRFTokenCookie(w http.ResponseWriter, cfg CSRFConfig)

ClearCSRFTokenCookie removes the CSRF token cookie.

func ConcurrencyLimit added in v0.1.2 

func ConcurrencyLimit(maxConcurrent int) func(http.Handler) http.Handler

ConcurrencyLimit creates a middleware that limits the number of concurrent requests using a semaphore pattern. When the limit is reached, new requests receive a 503 Service Unavailable response.

A maxConcurrent value of 0 or less disables the limit.

func ContextLogger added in v0.1.2 

func ContextLogger(log *logger.Logger) func(http.Handler) http.Handler

ContextLogger injects a request-scoped logger into the request context. The logger is enriched with request_id and user_id (when available). Services can retrieve it via logger.FromContext(ctx) for automatic request correlation in logs.

func Decompress 

func Decompress(config *DecompressConfig) func(http.Handler) http.Handler

Decompress middleware decompresses request bodies based on Content-Encoding header. Supports gzip and zstd compression.

This middleware should be placed BEFORE body limit middleware to properly limit the decompressed size, not the compressed size.

Example: 

router.Use(middleware.Decompress(nil))
router.Use(middleware.BodyLimit(50 * 1024 * 1024)) // 50MB decompressed limit

func DecompressForIngest 

func DecompressForIngest() func(http.Handler) http.Handler

DecompressForIngest is a variant specifically for ingest endpoints. It has a higher size limit (100MB) to accommodate large scan reports. SECURITY: Maintains zipbomb protection with higher limits.

func DistributedRateLimit 

func DistributedRateLimit(cfg DistributedRateLimitConfig) func(http.Handler) http.Handler

DistributedRateLimit creates middleware using Redis-backed rate limiting. Essential for production multi-instance deployments where in-memory rate limiting is insufficient.

Example usage: 

rateLimiter, _ := redis.NewRateLimiter(client, "api", 100, time.Minute, log)
adapter := redis.NewMiddlewareAdapter(rateLimiter)
router.Use(middleware.DistributedRateLimit(middleware.DistributedRateLimitConfig{
    Limiter: adapter,
    Logger:  log,
}))

func EndpointKeyFunc 

func EndpointKeyFunc(r *http.Request) string

EndpointKeyFunc returns a key function that includes the endpoint. Useful for per-endpoint rate limiting.

HasAnyPermission checks if the user has any of the specified permissions.

func HasPermission 

func HasPermission(ctx context.Context, permission string) bool

HasPermission checks if the user has a specific permission. Owner/Admin (IsAdmin flag in JWT) bypass permission checks - they have almost all permissions. Member/Viewer/Custom roles: permissions fetched from DB (not in JWT). For owner-only operations, use IsOwner() or RequireOwner() middleware.

func HasPermissionFromCache 

func HasPermissionFromCache(ctx context.Context, permission string) bool

HasPermissionFromCache checks if user has a permission using fetched permissions. Unlike HasPermission which uses JWT permissions + IsAdmin bypass, this always uses the latest permissions from cache.

NOTE: For backward compatibility, use HasPermission which still works. This function is for explicit cache-based permission checks.

func HasTenantAccess 

func HasTenantAccess(ctx context.Context, tenantID string) bool

HasTenantAccess checks if the user has access to a specific tenant.

func HasTenantRole 

func HasTenantRole(ctx context.Context, tenantID string, requiredRole string) bool

HasTenantRole checks if user has a specific role (or higher) in a tenant.

func IsAdmin 

func IsAdmin(ctx context.Context) bool

IsAdmin checks if the user has admin flag set (owner or admin role). When true, the user bypasses general permission checks. For owner-only operations (team delete, billing), use IsOwner() instead.

func IsOwner 

func IsOwner(ctx context.Context) bool

IsOwner checks if the user has the owner role. Use this for owner-only operations like team deletion, billing management.

func IsPermissionStale 

func IsPermissionStale(ctx context.Context) bool

IsPermissionStale returns true if the JWT permission version doesn't match Redis.

func IsPlatformAdmin 

func IsPlatformAdmin(ctx context.Context) bool

IsPlatformAdmin checks if the user has platform admin privileges. Platform admins can manage platform-wide resources like platform agents. This is typically granted to OpenCTEM staff or system administrators.

Platform admin is determined by: 1. Having "platform_admin" role in RealmAccess (for OIDC/Keycloak) 2. Being the system admin (for local auth - checks specific user IDs or emails)

func Logger 

func Logger(log *logger.Logger) func(http.Handler) http.Handler

Logger logs HTTP requests. This is the simple version that logs all requests.

func LoggerWithConfig 

func LoggerWithConfig(log *logger.Logger, cfg LoggerConfig) func(http.Handler) http.Handler

Metrics returns the Prometheus metrics middleware.

func MustGetAdminUser 

func MustGetAdminUser(ctx context.Context) *admin.AdminUser

MustGetAdminUser extracts admin user from context or panics if not found. Use this in handlers protected by Authenticate() middleware.

func MustGetTenantID 

func MustGetTenantID(ctx context.Context) string

Usage: 

adminRouter.Use(PlatformAdminAuthMiddleware)
adminRouter.Use(PlatformAdminRLSMiddleware(db, log))
adminRouter.Get("/all-findings", handler.ListAllFindings)

func RLSContextMiddleware 

func RLSContextMiddleware(db *sql.DB, log *logger.Logger) func(http.Handler) http.Handler

RLSContextMiddleware sets the PostgreSQL session variable for Row Level Security. This middleware should be applied AFTER authentication middleware.

How it works:

  1. Extracts tenant_id from the authenticated context
  2. Begins a database transaction
  3. Sets `app.current_tenant_id` session variable for RLS policies
  4. Stores the transaction in context for handlers to use
  5. Commits/rollbacks based on response status

Usage in routes: 

router.Use(authMiddleware)
router.Use(RLSContextMiddleware(db, log))
router.Get("/findings", handler.ListFindings)  // RLS automatically filters

func RateLimit 

func RateLimit(cfg *config.RateLimitConfig, log *logger.Logger) func(http.Handler) http.Handler

RateLimit creates a rate limiting middleware from config. Note: For proper cleanup, use RateLimitWithStop instead.

func RateLimitWithStop 

func RateLimitWithStop(cfg *config.RateLimitConfig, log *logger.Logger) (func(http.Handler) http.Handler, func())

RateLimitWithStop creates a rate limiting middleware and returns a stop function. The stop function should be called during graceful shutdown.

func RecoveryWithConfig 

func RecoveryWithConfig(log *logger.Logger, isProduction bool) func(http.Handler) http.Handler

RecoveryWithConfig is like Recovery but accepts a production mode flag. SECURITY: In production, stack traces are omitted to prevent sensitive path/code information from being exposed in logs.

RequireDeletePermission allows owner and admin roles only.

func RequireLocalUser 

func RequireLocalUser() func(http.Handler) http.Handler

RequireLocalUser ensures a local user exists in context. Use this for endpoints that require user data from the local database.

func RequireMembership 

func RequireMembership(tenantRepo tenant.Repository) func(http.Handler) http.Handler

RequireMembership verifies the authenticated user is a member of the tenant AND that the membership is currently active (not suspended). This is the canonical enforcement point for member suspension — it runs on every tenant-scoped request, so suspension takes effect immediately even if the user is holding a still-valid JWT.

Must be used after KeycloakAuth, UserSync, and TenantContext middleware.

func RequireMinTeamRole 

func RequireMinTeamRole(minRole tenant.Role) func(http.Handler) http.Handler

Use this for sensitive operations that only the owner should perform: - TeamDelete: Deleting the tenant - BillingManage: Managing billing settings - GroupsDelete, PermissionSetsDelete, AssignmentRulesDelete: Deleting access control resources

func RequirePlatformAdmin 

func RequirePlatformAdmin() func(http.Handler) http.Handler

RequirePlatformAdmin creates a middleware that requires platform admin access. Platform admins can manage OpenCTEM's shared infrastructure like platform agents. This is for OpenCTEM operators, not regular tenant admins.

RequireRole checks if the user has one of the required roles.

func RequireTeamAdmin 

func RequireTeamAdmin() func(http.Handler) http.Handler

func RequireTenant 

func RequireTenant() func(http.Handler) http.Handler

RequireTenant ensures the request has a valid tenant ID.

func RequireTenantRole 

func RequireTenantRole(roles ...tenant.Role) func(http.Handler) http.Handler

func SetCSRFTokenCookie 

func SetCSRFTokenCookie(w http.ResponseWriter, token string, cfg CSRFConfig)

SetCSRFTokenCookie sets the CSRF token in a JavaScript-readable cookie. This is NOT httpOnly so that frontend JavaScript can read and send it in headers.

func SetCampaignContext added in v0.1.3 

func SetCampaignContext(ctx context.Context, role pentest.CampaignRole, status pentest.CampaignStatus, campaignID string) context.Context

SetCampaignContext returns a context with campaign role, status, and ID set.

func SetTeamDBContext 

func SetTeamDBContext(db *sql.DB) func(http.Handler) http.Handler

SetTeamDBContext sets the team context for database RLS.

func TenantContext 

func TenantContext(tenantRepo tenant.Repository) func(http.Handler) http.Handler

TenantContext extracts tenant ID from URL path parameter and adds to context. It expects the path parameter to be named "tenant" (e.g., /tenants/{tenant}/assets). The {tenant} can be either a tenant ID (UUID) or tenant slug.

func Timeout 

func Timeout(timeout time.Duration) func(http.Handler) http.Handler

Timeout adds a timeout to each request context. If the handler takes longer than the timeout, the request is canceled.

func Tracing added in v0.1.2 

func Tracing(serviceName string) func(http.Handler) http.Handler

Tracing returns an OpenTelemetry tracing middleware that creates spans for each HTTP request and propagates trace context.

func UnifiedAuth 

func UnifiedAuth(cfg UnifiedAuthConfig) func(http.Handler) http.Handler

UnifiedAuth creates an authentication middleware that supports both local and OIDC authentication. The middleware tries to validate tokens based on the configured auth provider: - "local": Only validates local JWT tokens - "oidc": Only validates Keycloak/OIDC tokens - "hybrid": Tries local first, then falls back to OIDC

Token extraction order: 1. Authorization header (Bearer <token>) 2. Query parameter "token" (for SSE/EventSource which can't send headers)

func UserKeyFunc 

func UserKeyFunc(r *http.Request) string

UserKeyFunc returns a key function that uses authenticated user ID. Falls back to IP address for unauthenticated requests.

func UserSync 

func UserSync(userService *app.UserService, log *logger.Logger) func(http.Handler) http.Handler

UserSync middleware syncs authenticated users to the local database. It runs AFTER auth middleware (UnifiedAuth or KeycloakAuth) and creates/updates user records. Performance optimization: - First request: creates user if not exists - Subsequent requests: only updates last_login_at every 24 hours This enables: - Local user management independent of Keycloak - User-specific data (preferences, profile) stored locally - Future migration away from Keycloak Supports both local auth (LocalClaimsKey) and OIDC auth (ClaimsKey).
