CVE-2026-77089 1 Commvault 1 Commvault 2026-09-10 N/A
Command Center API contained an authentication bypass issue affecting privilege management. Software customers upgrade to resolved maintenance release. Update Command Center.
CVE-2026-62759 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-09 7.5 High
Authentication bypass by spoofing in Windows Netlogon allows an unauthorized attacker to perform spoofing over an adjacent network.
CVE-2026-82563 2026-09-09 7.6 High
An attacker could impersonate the camera and place themselves in a man-in-the-middle or device-emulation position. This permits manipulation of device status responses, observation of application requests, and potential triggering of firmware-update behavior.
CVE-2026-82530 2026-09-09 5.3 Medium
IP2Location Country Blocker plugin for WordPress before 2.45.0 contains an access control bypass vulnerability that allows unauthenticated remote attackers to circumvent IP-based restrictions by forging the X-Real-IP HTTP header. Attackers can set the X-Real-IP header to an allowlisted IP address to bypass page, link, or site-wide access restrictions and access otherwise-blocked resources.
CVE-2026-45528 2026-09-09 N/A
In getManageSpaceActivityIntent of StorageManagerService.java, there is a possible LaunchAnyWhere chain due to an unsafe PendingIntent. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
CVE-2026-86196 1 Getgrav 2 Grav, Grav-plugin-api 2026-09-08 N/A
Grav API plugin versions before 1.0.20 build password reset links from the untrusted Host header in the forgot-password endpoint, allowing unauthenticated attackers to redirect reset tokens to attacker-controlled domains. Attackers can send password reset requests for any account with a malicious Host header, intercept the reset token from victim emails, and complete account takeover including super-admin accounts.
CVE-2026-19538 1 Nlnetlabs 1 Nsd 2026-09-08 7.5 High
The BLOCKED access control list items that are evaluated to deny access on the the proxy protocol port can be bypassed completely when connecting over TCP or TLS and sending the query twice on connection that is kept open.
CVE-2026-84186 1 Prestashop 1 Prestashop 2026-09-08 N/A
Vulnerability involving incorrect access control in the Tools::getRemoteAddr() function in PrestaShop, which allows the client’s IP address to be spoofed via the X-Forwarded-For header when the application is running behind a reverse proxy, load balancer or CDN. The application incorrectly processes the IP address string and uses the address controlled by the visitor rather than the one provided by the trusted infrastructure, allowing an unauthenticated remote attacker to cause the application to interpret their connection as originating from an arbitrary IP address. This condition allows IP-based controls, such as the maintenance mode allowlist, to be bypassed, as well as enabling the forgery of security and audit logs and the evasion of third-party mechanisms that rely on the IP address, such as geolocation checks, fraud detection or request throttling.
CVE-2026-86478 1 Jetbrains 1 Youtrack 2026-09-08 9.8 Critical
In JetBrains YouTrack before 2025.3.161254, 2026.1.14042 improper authentication in YouTrack Helpdesk allowed unauthenticated account takeover via a self-asserted email address
CVE-2026-84849 2 Brightplugins, Wordpress 2 Pre-orders For Woocommerce, Wordpress 2026-09-07 6.5 Medium
Unauthenticated Bypass Vulnerability in Pre-Orders for WooCommerce <= 2.3 versions.
CVE-2026-84766 2 Wordpress, Wpmanageninja 2 Wordpress, Fluent Booking 2026-09-07 5.9 Medium
Unauthenticated Bypass Vulnerability in FluentBooking Pro <= 2.2.1 versions.
CVE-2026-85432 1 Themoos 1 Core-moos 2026-09-04 8.2 High
MOOS core-moos through 10.4.0 fails to validate client identity in MOOSDB message processing, allowing authenticated attackers to attribute writes to other clients by supplying arbitrary source identifiers in serialized messages. Attackers can forge message origins and cancel third-party subscriptions by exploiting the disconnect between authenticated connection identity and wire-supplied source attribution.
CVE-2026-47845 2 Broadcom, Spring 2 Reactor Netty, Reactor Netty 2026-09-04 5.3 Medium
In specific scenarios, Reactor Netty HTTP Server may incorrectly evaluate the remote IP address when HAProxy Protocol is enabled. In order for this to happen, the application must be configured to use HAProxy Protocol. Reactor Netty 1.3.0 - 1.3.6 Reactor Netty 1.1.0 - 1.2.18 Reactor Netty 1.0.52 and earlier
CVE-2023-50224 1 Tp-link 72 Archer C1900, Archer C1900 Firmware, Archer C5 and 69 more 2026-09-03 6.5 Medium
TP-Link TL-WR841N dropbearpwd Improper Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. The issue results from improper authentication. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-19899.
CVE-2026-84358 1 Google 1 Chrome 2026-09-03 4.2 Medium
Improper privilege management in Downloads in Google Chrome prior to 152.0.7977.75 allowed a remote attacker who had compromised the renderer process to spoof address bar via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-14199 1 Grafana 2 Grafana, Grafana Enterprise 2026-09-03 7.1 High
Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
CVE-2026-82180 1 Eclipse 1 Arrowhead 2026-09-03 N/A
In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 when the MQTT API is enabled with the certificate authentication policy, CertificateMqttFilter parses an X.509 certificate that the client sends inside the MQTT message payload (the authentication field of MqttRequestTemplate) and treats its Subject DN as the authenticated identity. The certificate is decoded with CertificateFactory.generateCertificate() but its signature is never verified and its issuer chain is never validated against any trust store. Authorisation is reduced to two string comparisons on attacker-supplied data: the DN-qualifier must equal "sy" or "op", and the cloud-name part of the CN must match the server's. Both values are public (the cloud name is in the server's own TLS certificate). An attacker who can publish to the MQTT broker can therefore mint a self-signed certificate with CN=Sysop.<cloud>.<org>.arrowhead.eu, dnQualifier=op, send it as the authentication field, and be authenticated as the cloud's system operator with isSysOp == true. This passes the downstream ManagementServiceMqttFilter (request.isSysOp() → allowed) and gives full management access over MQTT. The HTTP CertificateFilter is not affected — it reads the certificate from jakarta.servlet.request.X509Certificate, which Tomcat populates only after a successful mTLS handshake against the configured trust store.
CVE-2026-19117 1 Delinea 1 Secret Server 2026-09-03 9.8 Critical
Under specific conditions, an attacker can register an attacker-controlled FIDO2 credential against a target account and then authenticate as that user. This issue affects on-premises deployments only.
CVE-2026-73742 2 Arubanetworks, Hewlett Packard Enterprise (hpe) 2 Fabric Composer, Fabric Composer 2026-09-03 4.3 Medium
A vulnerability in an API endpoint of HPE Networking Fabric Composer could allow an authenticated low privilege operator user to spoof the source address attributed to their requests. Successful exploitation could allow an attacker to cause inaccurate attribution information to be recorded on the affected system.
CVE-2026-84476 1 Wwbn 1 Avideo 2026-09-02 7.5 High
WWBN AVideo fails to validate trusted proxies before accepting X-Real-IP and X-Forwarded-For headers, allowing attackers to spoof the client address used by enforceRateLimit(). Attackers can rotate the header value per request to bypass login rate limiting and perform unlimited credential guessing attacks.
