Title
SurrealDB before 3.1.0 Denial of Service via malformed RPC use
Summary
SurrealDB versions before 3.1.0 contain a denial of service vulnerability in the RPC use handler that panics when db is set without a namespace. Unauthenticated attackers can send a malformed WebSocket message to the /rpc endpoint to crash the server process.

CVE-2026-63403 (GCVE-0-2026-63403)

Title
Faktory: Unrecovered panic in command handlers allows full-server denial of service
Summary
Faktory is a language-agnostic background job server. In versions prior to 1.10.0, the server is vulnerable to an unauthenticated denial of service in which a single malformed command crashes the entire process. Its wire protocol is line-based, and several command handlers slice or index the received line at a fixed offset, such as cmd[5:] for PUSH or qs[0] for QUEUE, without checking that a payload is present. Sending a bare verb with no payload, for example PUSH, ACK, FAIL, BEAT, PUSHB, or QUEUE, triggers a Go slice or index out-of-range panic. Because the codebase has no recover() anywhere in the command-dispatch path, an unrecovered panic in a handler goroutine terminates the whole Go process rather than just that connection, instantly disconnecting every other client, worker, and in-flight job. The attack requires only a connection to the command port and completion of the trivial handshake, with no credentials when no password is configured, and can be repeated to keep the service down indefinitely. This issue is fixed in version 1.10.0.

CVE-2026-63341 (GCVE-0-2026-63341)

Vulnerability from cvelistv5 – Published: 2026-10-30 22:09 – Updated: 2026-11-05 02:57

Title
Aedes has Uncaught Exception and Uncontrolled Resource Consumption
Summary
Aedes is an MQTT broker that can run on any stream server. Prior to 1.1.1, the MQTT broker does not bound topic depth or structural complexity before passing topics through `mqemitter` into `qlobber`. A `PUBLISH`, `SUBSCRIBE`, or registered `Will` message containing an excessively deep topic can reach `qlobber._split_words` in `lib/qlobber.js` and trigger an uncaught `too many words` exception. Calls from `handlers/subscribe.js` and the publishing logic are not protected against that exception, so it escapes to the `Node.js event loop` and terminates the entire broker. The `Will` path is independently reachable when a client disconnects ungracefully: it calls `broker.publish` directly and bypasses the `PUBLISH` handler. An attacker must be able to establish an `MQTT session`, authenticated or unauthenticated according to broker configuration. A successful attack disconnects all legitimate clients and prevents reconnection until the broker process restarts. This issue is fixed in version 1.1.1.

Prior to 1.1.1, the MQTT broker does not bound topic depth or structural complexity before passing topics through `mqemitter` into `qlobber`. A `PUBLISH`, `SUBSCRIBE`, or registered `Will` message containing an excessively deep topic can reach `qlobber._split_words` in `lib/qlobber.js` and trigger an uncaught `too many words` exception. Calls from `handlers/subscribe.js` and the publishing logic are not protected against that exception, so it escapes to the `Node.js event loop` and terminates the entire broker. The `Will` path is independently reachable when a client disconnects ungracefully: it calls `broker.publish` directly and bypasses the `PUBLISH` handler. An attacker must be able to establish an `MQTT session`, authenticated or unauthenticated according to broker configuration. A successful attack disconnects all legitimate clients and prevents reconnection until the broker process restarts. This issue is fixed in version 1.1.1."

CVE-2026-62994 (GCVE-0-2026-62994)

Vulnerability from cvelistv5 – Published: 2026-07-16 19:39 – Updated: 2026-07-17 11:12

Title
CoreDNS `k8s_external` headless AXFR can emit an empty transfer batch that panics the `transfer` plugin
Summary
CoreDNS is a DNS server written in Go. From 1.9.4 until 1.14.5, a network DNS client allowed to request AXFR for a CoreDNS zone can trigger a panic when CoreDNS is configured with k8s_external headless-service zone transfers and Kubernetes contains a headless service endpoint with no declared ports; plugin/kubernetes/object/endpoint.go creates Port: -1, plugin/k8s_external/msg_to_dns.go skips that service, plugin/k8s_external/transfer.go sends an empty []dns.RR batch, and plugin/transfer/transfer.go indexes records[0] without checking the batch is non-empty. This issue is fixed in version 1.14.5.

Title
request-filtering-agent: Synchronous throw from createConnection() for literal private-IP hosts bypasses req.on('error'), crashing the Node.js process
Summary
request-filtering-agent is an http(s).Agent implementation that blocks requests to Private/Reserved IP addresses. Prior to 3.2.1, RequestFilteringHttpAgent and RequestFilteringHttpsAgent synchronously threw from createConnection when rejecting a literal private-IP host such as 169.254.169.254 or 127.0.0.1. Because Node.js http.request and http.get expect connection failures to be delivered asynchronously, the throw bypassed req.on('error') and became an uncaught exception that could terminate the application process. Hostnames resolved through the asynchronous lookup path were not affected by this error-delivery asymmetry. This issue is fixed in version 3.2.1.

Title
websocket-driver: Denial of service via malformed Host header
Summary
websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.2, WebSocket::Driver.server() passes a malformed Host header to URI.parse in lib/websocket/http/request.rb without catching URI::InvalidURIError, allowing a remote client to crash a TCP-backed WebSocket server when the application does not catch the error from parse(). This issue is fixed in version 0.8.2.

Title
libp2p-quic: Remote panic via certificate expiry race during QUIC handshake
Summary
libp2p-rust is the official Rust language implementation of the libp2p networking stack. Prior to 0.13.1, libp2p-quic could panic during an inbound QUIC handshake when a remote peer presented a valid short-lived libp2p TLS certificate and delayed the final TLS 1.3 handshake fragment until after the certificate expired. In the Quinn post-handshake upgrade path, transports/quic/src/connection/connecting.rs called libp2p_tls::certificate::parse a second time in remote_peer_id and used expect on the result. The repeated wall-clock validity check could reject the now-expired certificate, causing the expect call to terminate any application exposing an affected libp2p-quic listener. This vulnerability is fixed in 0.13.1.

Title
OpenTelemetry JavaScript: Denial of service in `JaegerPropagator` via unhandled exception on a malformed header
Summary
OpenTelemetry JavaScript is the OpenTelemetry JavaScript client. Prior to 2.9.0, @opentelemetry/propagator-jaeger decodes incoming uber-trace-id and uberctx-* HTTP header values with decodeURIComponent() without handling decode errors, allowing an unauthenticated remote attacker to send a malformed percent-encoded value that throws an uncaught URIError and terminates a Node.js process using JaegerPropagator as the active propagator. This issue is fixed in version 2.9.0.

Title
Excelize: Negative shared-string index causes panic in GetCellValue and GetRows
Summary
Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, Excelize parses shared-string cell values with strconv.Atoi and checks only the upper bound before indexing the shared string slice, allowing an XLSX file containing a shared-string cell with -1 to trigger sharedStrings[-1] and panic when read through GetCellValue or GetRows. This issue is fixed in version 2.11.0.
