Apache Kafka Clients accept configuration data for setting the SASL/OAUTHBEARER connection with the brokers, including \"sasl.oauthbearer.token.endpoint.url\" and \"sasl.oauthbearer.jwks.endpoint.url\". Apache Kafka allows clients to read an arbitrary file and return the content in the error log, or sending requests to an unintended location. In applications where Apache Kafka Clients configurations can be specified by an untrusted party, attackers may use the \"sasl.oauthbearer.token.endpoint.url\" and \"sasl.oauthbearer.jwks.endpoint.url\" configuratin to read arbitrary contents of the disk and environment variables or make requests to an unintended location. In particular, this flaw may be used in Apache Kafka Connect to escalate from REST API access to filesystem/environment/URL access, which may be undesirable in certain environments, including SaaS products. \n\nSince Apache Kafka 3.9.1/4.0.0, we have added a system property (\"-Dorg.apache.kafka.sasl.oauthbearer.allowed.urls\") to set the allowed urls in SASL JAAS configuration. In 3.9.1, it accepts all urls by default for backward compatibility. However in 4.0.0 and newer, the default value is empty list and users have to set the allowed urls explicitly.",

  "details": "## Summary\n\nHysteria\u0027s UDP relay treats the destination address as packet-scoped, but ACL and outbound policy are applied only once when a new UDP session is created. After an authenticated client opens a UDP session using an allowed first destination, later packets in the same `Session ID` can be sent to different destinations without re-running ACL evaluation.\n\nThis allows an authenticated user to bypass server-side UDP ACL rules and reach localhost or RFC1918/private-network UDP services from the server\u0027s network perspective, even when those destinations are explicitly rejected by ACL.\n\nVerified on current HEAD at commit `64c396385631579598cc29d5561bff98c439772f`.\n\n## Why this is a security issue\n\nThis report is not based on the assumption that one UDP session must be bound to one destination. The protocol and official client both support per-packet destinations:\n\n- `PROTOCOL.md:93-107` defines each `UDPMessage` as carrying its own `Addr` field.\n- `core/client/udp.go:52-62` exposes `Send(data, addr)`, allowing the same UDP session to send to arbitrary addresses.\n\nThe problem is that the security-relevant destination is packet-scoped, while ACL and outbound authorization are cached at session scope.\n\nThis is also not a `RequestHook`-bypass claim. I understand `RequestHook` is first-packet-oriented. The broader issue is that operator-configured ACL policy intended to block UDP destinations is not enforced on later packets within the same session.\n\nBecause the ACL documentation is presented as the mechanism for handling or blocking client requests, and includes examples of denying `udp/443` and private network CIDRs, operators can reasonably rely on ACL as a UDP egress security boundary. This boundary can currently be bypassed by reusing a previously authorized UDP session.\n\n## Root cause\n\nThe relevant flow appears to be:\n\n- `core/server/udp.go:280-299`: when a new session is created, the first destination is passed through `m.io.Hook(...)`, logged, and then `m.io.UDP(addr)` is called once to create the outbound UDP connection.\n- `core/server/server.go:397-398`: `m.io.UDP(addr)` delegates to `io.Outbound.UDP(reqAddr)`.\n- `app/cmd/server.go:1187-1190`: resolver, ACL, and actual outbounds are intentionally chained through the `Outbound` interface.\n- `core/server/udp.go:125`: the initial outbound connection is created only from the first packet via `DialFunc(firstMsg.Addr, firstMsg.Data)`.\n- `core/server/udp.go:92-111`: later packets in the same session take the current packet address and directly call `e.conn.WriteTo(dfMsg.Data, addr)` without re-running ACL or outbound policy evaluation.\n\nIn other words, destination selection is packet-scoped, but authorization is session-scoped.\n\n## Impact\n\nAny authenticated client that is allowed to use UDP relay can:\n\n- open one UDP session using an allowed first destination;\n- reuse the same session to send packets to destinations that ACL should reject;\n- reach UDP services on `127.0.0.1` or on RFC1918/private-network addresses from the server\u0027s network perspective.\n\nIn real deployments, this can expose internal-only UDP services such as:\n\n- internal DNS resolvers;\n- service discovery endpoints;\n- telemetry or metrics listeners;\n- local administrative daemons;\n- application-specific UDP services intended to be reachable only from localhost or the internal network.\n\nThis breaks the server\u0027s documented ACL-based UDP egress restrictions.\n\n## Reproduction\n\nTwo cases were reproduced with integration tests.\n\n### Case 1: localhost bypass\n\nACL:\n\n```text\ndirect(127.0.0.1, udp/\u003callowedPort\u003e)\nreject(127.0.0.1/32)\n```\n\nSteps:\n\n1. Start one UDP echo service on `127.0.0.1:\u003callowedPort\u003e`.\n2. Start another UDP echo service on `127.0.0.1:\u003cblockedPort\u003e`.\n3. Connect an authenticated Hysteria client and create one UDP session.\n4. Send a packet to the allowed loopback destination to establish the session.\n5. Reuse the same UDP session and send a packet to the blocked loopback destination.\n\nObserved result:\n\n- The second packet is relayed successfully and the blocked loopback service replies.\n\nExpected result:\n\n- The second packet should be rejected because `127.0.0.1/32` is denied by ACL.\n\n### Case 2: private-network bypass\n\nACL:\n\n```text\ndirect(127.0.0.1, udp/\u003callowedPort\u003e)\nreject(10.0.0.0/8)\n```\n\nor the corresponding local RFC1918 range, such as `192.168.0.0/16` or `172.16.0.0/12`.\n\nSteps:\n\n1. Start one UDP echo service on `127.0.0.1:\u003callowedPort\u003e`.\n2. Start another UDP echo service on a real RFC1918 address of the server host.\n3. Connect an authenticated Hysteria client and create one UDP session.\n4. Send a packet to the allowed loopback destination first.\n5. Reuse the same UDP session and send a packet to the RFC1918 destination.\n\nObserved result:\n\n- The private-address packet is relayed successfully and receives a reply.\n\nExpected result:\n\n- The packet should be rejected by ACL.\n\n## PoC and local evidence\n\nA local integration test file was added during verification:\n\n- `core/internal/integration_tests/udp_private_acl_bypass_test.go`\n\nThe two tests are:\n\n- `TestClientServerUDPACLBYPASSLoopback`\n- `TestClientServerUDPACLBYPASSPrivateIPv4`\n\nThey can be executed with:\n\n```bash\ngo test ./core/internal/integration_tests -run \u0027TestClientServerUDPACLBYPASS(Loopback|PrivateIPv4)\u0027 -count=1\n```\n\nThe tests pass locally and demonstrate that a destination blocked by ACL becomes reachable after the session is established with an allowed first destination.\n\n## Suggested fixes\n\nAny of the following would address the issue:\n\n1. Re-evaluate ACL and outbound policy for every defragmented UDP packet before forwarding it with `WriteTo`.\n2. Alternatively, enforce a single immutable destination per UDP session and reject destination changes after the first packet.\n3. Ensure logging and policy hooks are aligned with the chosen model so that policy enforcement and observability reflect the real per-packet destination.\n\n## Severity assessment\n\nSuggested CVSS v3.1 vector: `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L`\n\nThis reflects a network-reachable issue with low attack complexity, requiring only an authenticated client, no victim interaction, and allowing impact beyond the proxy process by exposing localhost and internal-network UDP resources from the server\u0027s trust boundary.",

  "details": "The SSRF protection in `requests-hardened` prior to version 1.2.1 fails to block IP addresses within the RFC 6598 Shared Address Space (`100.64.0.0/10`). An attacker who can supply arbitrary URLs to `requests-hardened` could exploit this gap to access internal services hosted within `100.64.0.0/10`. This is for example relevant in environments such as AWS EKS where `100.64.0.0/10` is commonly used as the default pod CIDR.\n\nThe impact is environment-dependent, deployments that utilize the affected CIDR range for internal networking are exposed to SSRF bypass, while others may not be affected.\n\nThe issue is resolved in version 1.2.1 by extending the IP filtering logic to explicitly block the RFC 6598 range in addition to standard private addresses, as well as blocking all other reserved addresses (such as multicast) to prevent the re-occurrence of similar issues.\n\nVersion 1.2.1 is now blocking the following CIDRs:\n\n- `192.88.99.0/24` - 6to4 relay anycast\n- `100.64.0.0/10` - CG-NAT\n- `5f00::/16` - IPv6 Segment Routing\n- `64:ff9b::/96` - used for IPv6 \u0026 IPv4 translation (NAT64)\n- `2001:20::/28` - ORCHIDv2 (overlay identifiers)\n- `224.0.0.0/4` - multicast\n- `ff00::/8` - multicast\n\n## Resources\n\n- https://github.com/python/cpython/issues/119812\n- https://github.com/saleor/requests-hardened/commit/b7403f88d3b3689e57435b75b51691a160aaeef5 - the fix itself\n- https://github.com/saleor/requests-hardened/commit/a266b3958bb142bca515b3c230fdea19fbda327c - follow up, adding additional support for outdated Python versions (`3.11.9` and `3.10.11` instead of only `3.11.15` and `3.10.20`)\n- https://github.com/saleor/requests-hardened/releases/tag/v1.2.1",

  "details": "## Impact\n\nOn an n8n instance with SSRF protection enabled, the MCP Client node sent requests to a user-supplied endpoint without routing them through that protection and without pinning the resolved address. An authenticated user who could create or edit a workflow could therefore cause the server to connect to internal or otherwise blocked hosts and read the responses back through the workflow, exposing internal services the SSRF protection was meant to protect.\n\n## Patches\n\nThe issue has been fixed in n8n versions 2.31.5 and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Disable the MCP Client node by adding it to the `NODES_EXCLUDE` environment variable.\n- Restrict network egress from the n8n host to block access to internal and link-local address ranges at the network level.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.",
