CVE-2026-45045 Média · 5.3 CWE-290 08/07/2026
Fiber: X-Real-IP Spoofing via Header.Add() in BalancerForward
Fiber is an Express inspired web framework written in Go. Prior to 3.3.0 and 2.52.14, the BalancerForward proxy helper in middleware/proxy/proxy.go uses Header.Add() instead of Header.Set() when injecting X-Real-IP, allowing an attacker-supplied first X-Real-IP value to be forwarded to upstream servers for logging, rate limiting, and access control. This issue is fixed in version 3.3.0 and 2.52.14.

n8n - Webhook Forgery via Unsigned POST Requests in ZendeskTrigger
n8n before versions 1.123.18 and 2.6.2 fails to verify HMAC-SHA256 signatures on Zendesk webhooks in the ZendeskTrigger node. Attackers who know the webhook URL can send unsigned POST requests to trigger workflows with arbitrary malicious data.
CVE-2026-24013 Crítica · 9.1 CWE-290 06/07/2026
Apache IoTDB: Authentication Bypass via Forged SessionID in Thrift RPC
Authentication Bypass by Spoofing vulnerability in Apache IoTDB. Certain Thrift RPC query handlers lack strict validation of the sessionId parameter. An attacker can construct requests with a forged sessionId and, without performing openSession authentication, receive valid query results. This allows authentication bypass and unauthorized reading of time-series data. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.
CVE-2026-14381 Média · 6.5 CWE-290 01/07/2026
Authentication Bypass by Spoofing em Google Chrome
Incorrect security UI in WebAppInstalls in Google Chrome prior to 150.0.7871.46 allowed a remote attacker to perform UI spoofing via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-58593 Alta · 7.5 CWE-290 01/07/2026
NodeBB - ActivityPub Author Spoofing via Unvalidated attributedTo Mapped to Local User
NodeBB does not bind the claimed author of an inbound ActivityPub object to the authenticated remote actor. The inbound middleware verifies the HTTP-signature actor and checks the origin of object.id, but never validates that attributedTo corresponds to the sender. In the object mock, attributedTo is used directly as a uid, and actors.assert silently ignores numeric identifiers (filtering them out without re-deriving the uid), so a federated remote actor can set attributedTo to a bare numeric value such as 1 and have the resulting post or private message created with that local uid as author, including the administrator account. This lets a remote attacker forge posts and direct messages attributed to arbitrary local users. Requires the ActivityPub/federation feature to be enabled.
CVE-2026-24270 Crítica · 9.8 CWE-290 01/07/2026
Authentication Bypass by Spoofing em NVIDIA AIStore framework
NVIDIA AIStore framework contains a vulnerability where an attacker could bypass authentication. A successful exploit of this vulnerability might lead to denial of service, escalation of privileges, information disclosure, and data tampering.

CVE-2026-13207 Alta · 7.5 CWE-290 30/06/2026
Frangoteam FUXA SCADA/HMI Authentication Bypass by Spoofing
FUXA versions 1.3.1 and prior contain an authentication bypass vulnerability via dot-segment path normalization in the REST API. The API router fails to normalize dot-segment sequences before applying authentication middleware, allowing unauthenticated requests to access protected endpoints by prefixing paths with dot-segments such as /api/./users, /api/./roles, and /api/project/../users. These requests bypass authentication checks and return sensitive user and role data without credentials.
CVE-2026-58370 Alta · 8.1 CWE-290 30/06/2026
Woodpecker < 3.15.0 - GitLab Approval Gate Bypass via Spoofable Commit Author Name
Woodpecker before 3.15.0 matches the ApprovalAllowedUsers bypass list against pipeline.Author. For the GitLab forge driver, pipeline.Author is populated from the git commit author name (commit.author.name) carried in the webhook payload, which is attacker-controlled and not verified by GitLab. A user who can open a merge request from a fork can set the commit author name to match an entry in ApprovalAllowedUsers, causing needsApproval to return false so the pipeline runs without the required approval. This defeats the fork-approval security boundary and allows execution of attacker-controlled pipeline steps on a Woodpecker agent and exfiltration of CI secrets exposed to the run. Other built-in forge drivers (Gitea, Forgejo, GitHub, Bitbucket) derive pipeline.Author from the forge-validated sender/actor identity and are not affected.
CVE-2026-7656 Média · 6.8 CWE-290 29/06/2026
Broken IPv6 Neighbor Discovery input validation allows spoofed RA/NS/NA acceptance in Zephyr net stack
The IPv6 Neighbor Discovery handlers in subsys/net/ip/ipv6_nbr.c (handle_ra_input, handle_ns_input, handle_na_input) used an incorrect boolean expression that combined the RFC 4861 validity checks with the ICMPv6 code check using the wrong operator precedence: the form was ((length/hop/source/target checks) && (icmp_hdr->code != 0)). Because every legitimate ND message carries ICMPv6 code 0, an attacker setting code == 0 (the normal value) caused the entire predicate to evaluate false, so the packet was never dropped and all of the other checks were silently skipped. The bypassed checks include the mandatory Hop Limit == 255 verification (which proves an ND packet originated on-link and was not forwarded) and, for Router Advertisements, the requirement that the source be a link-local address, as well as multicast-target sanity checks. As a result, an adjacent on-link attacker — and, because the Hop-Limit-255 guard is bypassed, potentially a remote/off-link attacker whose packets would otherwise be rejected — can have forged Router Advertisement, Neighbor Solicitation, and Neighbor Advertisement messages accepted. A forged RA lets the attacker reconfigure the victim's default router, on-link prefixes (SLAAC), MTU, reachable/retransmit timers, and (with CONFIG_NET_IPV6_RA_RDNSS) DNS servers, while forged NS/NA enable neighbor-cache poisoning, enabling man-in-the-middle, traffic redirection, and denial of service. The flaw is an input-validation/authentication weakness rather than a memory-safety issue: the underlying packet-parsing primitives (net_pkt_get_data, net_pkt_read, net_pkt_skip) are independently bounds-safe and the validated length is the true buffer length, so skipping the length check causes no out-of-bounds access. The defect has existed since the logic was introduced in 2018 and shipped in all releases through v4.4.0; it is fixed by splitting the condition so any failing check drops the packet.
CVE-2026-52690 Média · 5.9 CWE-290 25/06/2026
Spoofed answers can mark an authoritative non-EDNS capable
Spoofing replies to Recursor might mark an IP of an authoritative server as not supporting EDNS, causing valdiation of DNSSEC records served by that server to fail.
CVE-2026-25119 Alta · 7.7 CWE-290 24/06/2026
Gogs: Authentication Bypass via Unvalidated Reverse Proxy Headers
Gogs is an open source self-hosted Git service. Prior to 0.14.3, when ENABLE_REVERSE_PROXY_AUTHENTICATION is enabled, Gogs accepts the configured authentication header (default: X-WEBAUTH-USER) directly from client requests without validating that the request originated from a trusted reverse proxy. Any remote attacker who can reach the Gogs service can forge this header to impersonate any user or trigger automatic account creation, completely bypassing authentication. This vulnerability is fixed in 0.14.3.
CVE-2026-47381 Média · 6.9 CWE-290 23/06/2026
NocoDB: Cross-Workspace Integration Use in Connection Test
NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, a user in one workspace could exercise another workspace's integration through the testConnection endpoint by supplying its ID, because the integration was fetched in a bypass scope and the caller's permission check matched any base in any workspace. This vulnerability is fixed in 2026.05.1.
CVE-2026-54308 Alta · 7.2 CWE-290 23/06/2026
n8n: Missing Token Validation on Microsoft Agent 365 Trigger Node
n8n is an open source workflow automation platform. Prior to 2.25.7 and 2.26.2, the MicrosoftAgent365Trigger and StripeTrigger node did not validate that inbound requests. As a result, an unauthenticated attacker who knows the webhook URL could submit a forged payload and cause the workflow to execute with attacker-controlled data. This vulnerability is fixed in 2.25.7 and 2.26.2.
CVE-2026-56357 Média · 5.3 CWE-290 22/06/2026
n8n - Webhook Forgery via Missing HMAC-SHA256 Signature Verification in GitHub Webhook Trigger
n8n before 1.123.15 and 2.5.0 contains a webhook forgery vulnerability in the GitHub Webhook Trigger node that fails to implement HMAC-SHA256 signature verification. Attackers who know the webhook URL can send unsigned POST requests to trigger workflows with arbitrary data, spoofing GitHub webhook events.
CVE-2026-49468 Crítica · 9.8 Exploit público CWE-290 22/06/2026
Proxy LiteLLM: bypass de autenticação por spoofing do cabeçalho Host (CVE-2026-49468)
LiteLLM é um servidor proxy (AI Gateway) para chamar APIs de LLM em formato OpenAI (ou nativo). Antes da versão 1.84.0, uma falha no tratamento do cabeçalho Host no proxy LiteLLM poderia, em condições específicas, permitir acesso não autenticado a rotas de gerenciamento protegidas. A camada de autenticação derivava a rota efetiva a partir de request.url.path em litellm/proxy/auth/auth_utils.py::get_request_route(), que o Starlette reconstrói a partir do cabeçalho Host. Um Host forjado podia, portanto, fazer o controle de autenticação avaliar uma rota diferente daquela despachada pelo FastAPI. Esta vulnerabilidade está corrigida na versão 1.84.0.
CVE-2026-49231 Média · 5.4 CWE-290 19/06/2026
Apache APISIX: Identity spoofing issue in APISIX opa plugin
Authentication Bypass by Spoofing vulnerability in opa plugin. An attacker could relay spoofed identity headers to upstream capitalising on non-default configuration in opa plugin. This could allow the attacker to assume higher privileges on the upstream service. This issue affects Apache APISIX: from 3.5.0 through 3.16.0. Users are recommended to upgrade to version 3.17.0, which fixes the issue.
CVE-2026-39999 Crítica · 9.1 CWE-290 19/06/2026

CVE-2026-50141 Alta · 7.1 CWE-290 18/06/2026
Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation
Woodpecker is a CI/CD engine. Starting in version 3.0.0 and prior to version 3.14.1, a vulnerability in Woodpecker CI's gRPC layer allowed any authenticated agent to impersonate any other agent on the same server by injecting a forged `agent_id` value into outgoing gRPC metadata. The server correctly verified the JWT token but then discarded the verified agent identity in favor of the client-supplied value. Version 3.14.1 patches the issue. As a workaround, disable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones.
CVE-2026-55202 Alta · 8.2 CWE-290 17/06/2026
Tinyproxy - Stathost Detection Bypass via Host Header Manipulation
Tinyproxy through 1.11.3, fixed in commit 09312a1, fails to properly validate the Host header during stathost detection, allowing unauthenticated attackers to access the stats page by injecting a matching Host header or bypass detection via port manipulation. Remote attackers can trigger unauthorized access to internal proxy statistics or misroute requests as transparent proxy connections to circumvent access controls.
CVE-2026-53857 Alta · 8.1 CWE-290 16/06/2026
OpenClaw < 2026.5.3 - Mutable Display Name Binding in Zalo allowFrom Policy
OpenClaw before 2026.5.3 contains a policy enforcement vulnerability where Zalo contacts with mutable display metadata could match allowFrom policy entries through display name changes. Attackers with mutable display names could receive agent responses intended for different Zalo identities when the feature is enabled.
