vulnerabilities

stdlib 1.25.4 (golang) pkg:golang/stdlib@1.25.4 Affected range >=1.25.0-0 <1.25.7 Fixed version 1.25.7 EPSS Score 0.017% EPSS Percentile 4th percentile Description During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake. Affected range <1.25.8 Fixed version 1.25.8 EPSS Score 0.031% EPSS Percentile 9th percentile Description url.Parse insufficiently validated the host/authority component and accepted some invalid URLs. Affected range >=1.25.0 <1.25.5 Fixed version 1.25.5 EPSS Score 0.022% EPSS Percentile 6th percentile Description Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption. Affected range >=1.25.0 <1.25.6 Fixed version 1.25.6 EPSS Score 0.032% EPSS Percentile 9th percentile Description The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.

google.golang.org/grpc 1.78.0 (golang) pkg:golang/google.golang.org/grpc@1.78.0 Improper Authorization Affected range <1.79.3 Fixed version 1.79.3 CVSS Score 9.1 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N EPSS Score 0.011% EPSS Percentile 1st percentile Description Impact What kind of vulnerability is it? Who is impacted? It is an Authorization Bypass resulting from Improper Input Validation of the HTTP/2 :path pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests where the :path omitted the mandatory leading slash (e.g., Service/Method instead of /Service/Method). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official grpc/authz package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with /) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present. Who is impacted? This affects gRPC-Go servers that meet both of the following criteria: They use path-based authorization interceptors, such as the official RBAC implementation in google.golang.org/grpc/authz or custom interceptors relying on info.FullMethod or grpc.Method(ctx). Their security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule). The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed :path headers directly to the gRPC server. Patches Has the problem been patched? What versions should users upgrade to? Yes, the issue has been patched. The fix ensures that any request with a :path that does not start with a leading slash is immediately rejected with a codes.Unimplemented error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string. Users should upgrade to the following versions (or newer): v1.79.3 The latest master branch. It is recommended that all users employing path-based authorization (especially grpc/authz) upgrade as soon as the patch is available in a tagged release. Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading? While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods: 1. Use a Validating Interceptor (Recommended Mitigation) Add an "outermost" interceptor to your server that validates the path before any other authorization logic runs: func pathValidationInterceptor(ctx context.Context, req any, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (any, error) { if info.FullMethod == "" || info.FullMethod[0] != '/' { return nil, status.Errorf(codes.Unimplemented, "malformed method name") } return handler(ctx, req) } // Ensure this is the FIRST interceptor in your chain s := grpc.NewServer( grpc.ChainUnaryInterceptor(pathValidationInterceptor, authzInterceptor), ) 2. Infrastructure-Level Normalization If your gRPC server is behind a reverse proxy or load balancer (such as Envoy, NGINX, or an L7 Cloud Load Balancer), ensure it is configured to enforce strict HTTP/2 compliance for pseudo-headers and reject or normalize requests where the :path header does not start with a leading slash. 3. Policy Hardening Switch to a "default deny" posture in your authorization policies (explicitly listing all allowed paths and denying everything else) to reduce the risk of bypasses via malformed inputs.

go.opentelemetry.io/otel/sdk 1.38.0 (golang) pkg:golang/go.opentelemetry.io/otel/sdk@1.38.0 Untrusted Search Path Affected range >=1.21.0 <1.40.0 Fixed version 1.40.0 CVSS Score 7 CVSS Vector CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H EPSS Score 0.008% EPSS Percentile 1st percentile Description Impact The OpenTelemetry Go SDK in version v1.20.0-1.39.0 is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in sdk/resource/host_id.go executes the ioreg system command using a search path. An attacker with the ability to locally modify the PATH environment variable can achieve Arbitrary Code Execution (ACE) within the context of the application.
