Descripción técnica

Improper Input Validation vulnerability in ash-project ash_graphql allows an unauthenticated client to crash a relay node(id: ...) query with an unhandled KeyError. AshGraphql.Graphql.Resolver.resolve_node/2 decodes the client-supplied global ID with decode_relay_id/1, which only base64-decodes the string and splits it on : without validating the type segment. The decoded type is passed straight to Map.fetch!(type_to_domain_and_resource_map, type). Because fetch! raises on a missing key, a relay ID whose type segment is a valid atom that is not a relay-exposed type aborts the resolver before its resolve/2 clauses and their rescue handlers run, so the error never becomes a GraphQL error and may expose a stacktrace. Common resource names are easy to guess. The fix uses Map.fetch/2 and returns an Invalid node id error for unknown types. This issue affects ash_graphql: from 0.27.0 before 1.11.0.

——0A security flaw has been discovered in Linux Foundation Magma 1.9.0. This impacts an unknown function of the component NGSetupRequest Handler. Performing a manipulation of the argument NG-IoT-DefaultPagingDRX results in improper input validation. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.7h CVE-2026-826487.1 ALT

——0WWBN AVideo contains a server-side request forgery filter bypass vulnerability in the isSSRFSafeURL function that fails to normalize NAT64 addresses written in hexadecimal form. Attackers can bypass SSRF protections by supplying hex-encoded NAT64 addresses like 64:ff9b::a9fe:a9fe to reach cloud metadata services and loopback interfaces.8h CVE-2026-826397.5 ALT

——0NextChat versions from 2.15.8 through 2.16.1 contain an improper URL validation vulnerability in the proxy endpoint that allows attackers to obtain the server's OpenAI API key. The x-base-url header is validated using substring matching instead of hostname parsing, allowing any URL containing 'api.openai.com' to pass validation and receive the server's credentials in the Authorization header.9h CVE-2026-55068—

——11free5GC is an open-source implementation of the 5G core network. In 4.2.2 and earlier, the NRF RegisterNFInstance handler at PUT /nnrf-nfm/v1/nf-instances/{nfInstanceID} accepts NF Profiles without enforcing UUID format, nfStatus enum values, heartBeatTimer ranges, mandatory profile fields, or nfServices.ipEndPoints address constraints. The invalid profiles are persisted in the MongoDB NfProfile collection and returned by NFDiscover, allowing an attacker with SBI access to advertise attacker-controlled network-function endpoints and redirect control-plane signaling. This can expose credentials and signaling, alter service discovery integrity, and deny service across network functions that trust the NRF. This issue is fixed in version 4.2.3.2d CVE-2026-78009—

——3The EmbeddedHeadersJsonMessageMapper defaults to an overly permissive header parsing posture in its constructor. When decodeNativeFormat processes raw byte payloads, it deserializes embedded JSON headers into a plain Map and constructs a GenericMessage with MutableMessageHeaders without sanitizing or filtering untrusted header names by default.
