The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains an IP restriction bypass vulnerability in the login process. The application restricts user logins based on the IP address associated with a branch location, but the client IP address is derived from the HTTP X-Forwarded-For header when that header is present. An attacker with valid branch user credentials can manipulate the X-Forwarded-For header during login to spoof the expected branch IP address and obtain a valid authenticated session from an unauthorized network location.

Authentication Bypass by Spoofing vulnerability in AAM Plugin Advanced Access Manager allows URL Encoding.
This issue affects Advanced Access Manager: from n/a through 7.1.0.
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.220, the email processing pipeline in FreeScout's FetchEmails command has two code paths for identifying agent (user) replies based on In-Reply-To / References headers. The notification reply path (notify-{thread_id}-{user_id}-...) extracts thread_id and user_id directly from the Message-ID without HMAC verification. An external attacker who can spoof the From address of a helpdesk agent can inject messages that FreeScout processes as legitimate agent replies — which are then automatically forwarded to customers via the legitimate SMTP server. This vulnerability is fixed in 1.8.220.
Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO's WebSocket control plane trusts client-supplied identity and role fields in task messages. A client connection can register as a normal device, but later send a TASK message claiming client_type="constellation" and target_id=<victim-device-id>. The server trusts the role and target values from the wire message rather than enforcing the role registered for that WebSocket connection. As a result, any authenticated WebSocket client with the shared server token can spoof the higher-privilege constellation role and dispatch attacker-controlled tasks to another connected device. The same client registry also allows duplicate client_id registration, overwriting an existing live client's stored websocket, role, and task protocol. This is an authenticated WebSocket role/identity spoofing issue leading to peer task hijacking.
CVE-2026-8676 is a high-severity vulnerability in silabs.com Simplicity SDK that allows an attacker to downgrade the security of a Bluetooth LE connection. The attacker can delete an existing bond, spoof the bonded device, and create a new bond, effectively bypassing authentication. This vulnerability has a CVSS score of 8.8, indicating a significant impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
A critical authentication bypass vulnerability (CVE-2026-39831) exists in golang.org/x/crypto/ssh affecting FIDO/U2F security key types. The Verify() method fails to check the User Presence flag, allowing signatures generated without physical user interaction to be accepted. This flaw enables unauthorized use of hardware security keys without user touch unless mitigated by a specific extension in Permissions.Extensions. The vulnerability has a high CVSS score of 9.1 and impacts authentication security.
Trilium Notes is a cross-platform, hierarchical note taking application focused on building large personal knowledge bases. In versions 0.102.1 and prior, the Electron configuration is vulnerable to TCC Bypass via Prompt Spoofing, allowing local attackers to trigger misleading macOS permission prompts by running malicious code under the identity of the trusted app. The root cause is that the RunAsNode fuse allows launching the app in a special Node.js mode using -e to execute arbitrary system commands with Trilium Notes's permissions and identity. An attacker can leverage this through a subprocess to request any sensitive permissions, such as access to hardware (camera, microphone) and TCC-protected files, causing the TCC system prompt to appear as if the request came from Trilium rather than the attacker's code, because macOS treats the subprocess as part of the parent application. Exploitation allows access to TCC-protected resources like the screen, camera, microphone, and folders such as ~/Documents and ~/Downloads, undermining macOS's security model and UI integrity through social engineering. This issue has been fixed in version 0.102.2.
A session fixation vulnerability was found in Keycloak's login-actions endpoints. An unauthenticated attacker could exploit this flaw by pre-creating an authentication session and tricking a victim into visiting a maliciously crafted link. By leveraging the /login-actions/restart endpoint—which processes session handles without adequate CSRF protection or cookie ownership validation—an attacker can reset the authentication flow state. This causes Single Sign-On (SSO) to authenticate the victim transparently upon clicking the link, allowing the attacker to hijack the required-action form without needing the victim's credentials. A successful exploit could lead to complete account takeover, including highly privileged administrative accounts.
Fleet is open source device management software. Prior to version 4.80.1, a vulnerability in Fleet's IP extraction logic allows unauthenticated attackers to bypass API rate limiting by spoofing client IP headers. This may allow brute-force login attempts or other abuse against Fleet instances exposed to the public internet. Fleet extracted client IP addresses from request headers (`True-Client-IP`, `X-Real-IP`, `X-Forwarded-For`) without validating that those headers originate from a trusted proxy. The extracted IP is used as the key for rate limiting and IP ban decisions. As a result, an attacker could rotate the value of these headers on each request, causing Fleet to treat each attempt as coming from a different client. This effectively bypasses per-IP rate limits on sensitive endpoints such as the login API, enabling unrestricted brute-force or credential stuffing attacks. This issue primarily affects Fleet instances that are directly exposed to the internet without a reverse proxy that overwrites forwarded-IP headers. Instances behind a properly configured proxy or WAF are less affected. Version 4.80.1 contains a patch. If an immediate upgrade is not possible, administrators should ensure Fleet is deployed behind a reverse proxy (e.g., nginx, Cloudflare, AWS ALB) that overwrites `X-Forwarded-For` with the true client IP, and apply rate limiting at the proxy or WAF layer.
Fleet versions prior to 4.82.0 have an authentication bypass vulnerability in the Windows MDM enrollment flow. The software accepts Azure AD tokens from any tenant because it validates JWT signatures using Microsoft's multi-tenant JWKS endpoint but does not enforce audience or issuer claims. This flaw allows attackers with access to any Azure AD tenant to use valid Microsoft-signed tokens to enroll unauthorized devices and interact with Fleet's MDM APIs. Sensitive enrollment secrets may be exposed during device management. Version 4.82.0 includes a patch that addresses this issue. Users unable to upgrade immediately should disable Windows MDM as a temporary mitigation.
Fleet is open source device management software. Prior to version 4.80.1, Fleet trusted client-supplied IP address headers when determining the source IP for incoming requests. This allowed authenticated and unauthenticated clients to spoof their apparent IP address and bypass per-IP rate limiting controls. Fleet determines a client’s public IP address using HTTP headers such as X-Forwarded-For, X-Real-IP, and/or True-Client-IP. These headers were trusted without validation. An attacker could supply arbitrary values in these headers, causing Fleet to treat each request as originating from a different IP address. This could allow an attacker to bypass per-IP rate limits and increase the effectiveness of brute-force or password-spraying attempts against authentication endpoints. This issue does not allow authentication bypass, privilege escalation, data exposure, or remote code execution on its own. Version 4.80.1 contains a patch. As a workaround, run Fleet behind a trusted reverse proxy or load balancer that overwrites client IP headers.
A vulnerability in the azureauthextension component of opentelemetry-collector-contrib versions 0.124.0 through 0.150.0 allows server-side authentication bypass. The extension improperly validates Azure access tokens by comparing them as strings without proper JWT validation and uses the client-supplied Host header to determine token scope. This flaw enables an attacker holding any valid Azure token for any scope the collector's identity can mint to authenticate to any OpenTelemetry receiver using azure_auth. Tokens remain valid for their full lifetime, typically several hours. The vulnerability has a high severity with a CVSS score of 8.1.
When NGINX Plus or NGINX Open Source are configured to use the HTTP/3 QUIC module, an attacker may be able to spoof their source IP address allowing for bypass of authorization or bypass of rate limiting. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
