| CVE-2017-12337 | Cri | 0.65 | 9.8 | 0.13 | Nov 16, 2017 | A vulnerability in the upgrade mechanism of Cisco collaboration products based on the Cisco Voice Operating System software platform could allow an unauthenticated, remote attacker to gain unauthorized, elevated access to an affected device. The vulnerability occurs when a refresh upgrade (RU) or Prime Collaboration Deployment (PCD) migration is performed on an affected device. When a refresh upgrade or PCD migration is completed successfully, an engineering flag remains enabled and could allow root access to the device with a known password. If the vulnerable device is subsequently upgraded using the standard upgrade method to an Engineering Special Release, service update, or a new major release of the affected product, this vulnerability is remediated by that action. Note: Engineering Special Releases that are installed as COP files, as opposed to the standard upgrade method, do not remediate this vulnerability. An attacker who can access an affected device over SFTP while it is in a vulnerable state could gain root access to the device. This access could allow the attacker to compromise the affected system completely.

| CVE-2017-12251 | Cri | 0.65 | 9.9 | 0.03 | Oct 19, 2017 | A vulnerability in the web console of the Cisco Cloud Services Platform (CSP) 2100 could allow an authenticated, remote attacker to interact maliciously with the services or virtual machines (VMs) operating remotely on an affected CSP device. The vulnerability is due to weaknesses in the generation of certain authentication mechanisms in the URL of the web console. An attacker could exploit this vulnerability by browsing to one of the hosted VMs' URLs in Cisco CSP and viewing specific patterns that control the web application's mechanisms for authentication control. An exploit could allow the attacker to access a specific VM on the CSP, which causes a complete loss of the system's confidentiality, integrity, and availability. This vulnerability affects Cisco Cloud Services Platform (CSP) 2100 running software release 2.1.0, 2.1.1, 2.1.2, 2.2.0, 2.2.1, or 2.2.2. Cisco Bug IDs: CSCve64690. | |

| CVE-2026-5229 | Cri | 0.64 | 9.8 | 0.00 | May 15, 2026 | The Form Notify plugin for WordPress is vulnerable to Authentication Bypass in versions up to and including 1.1.10. This is due to the plugin trusting user-controlled cookie data to determine which WordPress account to authenticate after a LINE OAuth login. When LINE doesn't provide an email address (which is common), the plugin falls back to reading the 'form_notify_line_email' cookie value without verifying that the LINE account is associated with that email address. This makes it possible for unauthenticated attackers to gain access to any user account on the site, including administrator accounts, by completing a LINE OAuth flow with their own LINE account while injecting a malicious cookie containing the target victim's email address. | |
| CVE-2026-8181 | Cri | 0.64 | 9.8 | 0.00 | May 14, 2026 | The Burst Statistics – Privacy-Friendly WordPress Analytics (Google Analytics Alternative) plugin for WordPress is vulnerable to Authentication Bypass in versions 3.4.0 to 3.4.1.1. This is due to incorrect return-value handling in the `is_mainwp_authenticated()` function when validating application passwords from the Authorization header. This makes it possible for unauthenticated attackers, with knowledge of an administrator username, to impersonate that administrator for the duration of the request by supplying any random Basic Authentication password achieving privilege escalation. | |
| CVE-2026-35579 | Cri | 0.64 | 9.8 | 0.00 | May 5, 2026 | CoreDNS is a DNS server written in Go. In versions prior to 1.14.3, the gRPC, QUIC, DoH, and DoH3 transport implementations incorrectly handle TSIG authentication. For gRPC and QUIC, the server checks whether the TSIG key name exists in the configuration but never calls dns.TsigVerify() to validate the HMAC. If the key name matches a configured key, the tsigStatus field remains nil and the tsig plugin treats the request as successfully authenticated regardless of the MAC value. For DoH and DoH3, the issue is more severe: the DoHWriter.TsigStatus() method unconditionally returns nil, and the server never inspects the TSIG record at all. Any request containing a TSIG record is treated as authenticated over DoH and DoH3, even if the key name is invalid and the MAC is arbitrary. An unauthenticated network attacker can exploit this to bypass TSIG-protected functionality such as AXFR/IXFR zone transfers, dynamic DNS updates, or other TSIG-gated plugin behavior. The DoH and DoH3 variants have a lower exploitation bar because the attacker does not need to know a valid TSIG key name. This issue has been fixed in version 1.14.3. As a workaround, disable gRPC, QUIC, DoH, and DoH3 listeners where TSIG authentication is required, or restrict network-level access to affected transport ports to trusted sources only. | |
| CVE-2026-27960 | Cri | 0.64 | 9.8 | 0.00 | May 5, 2026 | OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. In versions 6.6.0 through 6.9.12, there is a privilege escalation vulnerability that can be exploited by unauthenticated attackers to query the API as any existing user, including the default admin account. This issue has been fixed in version 6.9.13. As a workaround, the default admin can be disabled using the `APP__ADMIN__EXTERNALLY_MANAGED` configuration. | |
| CVE-2026-5722 | Cri | 0.64 | 9.8 | 0.00 | May 5, 2026 | The MoreConvert Pro plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.9.14. This is due to the guest waitlist verification flow not invalidating or regenerating verification tokens when the customer email address is changed. This makes it possible for unauthenticated attackers to authenticate as existing users, including administrators, by obtaining a valid guest verification token for an attacker-controlled email, changing the same guest customer email to the target account email through the public waitlist flow, and then using the original verification link. | |
| CVE-2026-35903 | Cri | 0.64 | 9.8 | 0.00 | Apr 27, 2026 | MERCURY MIPC252W IP camera 1.0.5 Build 230306 Rel.79931n contains an improper authentication vulnerability in the RTSP service. After successful Digest authentication in an initial DESCRIBE request, the device does not verify the Digest response parameter in subsequent RTSP requests within the same session. As a result, RTSP methods such as SETUP, PLAY, and TEARDOWN can be processed even when the Authorization header contains an empty or invalid response value, as long as the nonce and session identifier correspond to a previously authenticated session. This allows an attacker with network access to reuse session parameters and issue unauthorized RTSP control commands without computing a valid Digest response. | |
| CVE-2026-41276 | Cri | 0.64 | 9.8 | 0.00 | Apr 23, 2026 | Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, this vulnerability allows remote attackers to bypass authentication on affected installations of FlowiseAI Flowise. Authentication is not required to exploit this vulnerability. The specific flaw exists within the resetPassword method of the AccountService class. There is no check performed to ensure that a password reset token has actually been generated for a user account. By default the value of the reset token stored in a users account is null, or an empty string if they've reset their password before. An attacker with knowledge of the user's email address can submit a request to the "/api/v1/account/reset-password" endpoint containing a null or empty string reset token value and reset that user's password to a value of their choosing. This vulnerability is fixed in 3.1.0. | |
| CVE-2026-39324 | Cri | 0.64 | 9.8 | 0.00 | Apr 7, 2026 | Rack::Session is a session management implementation for Rack. From 2.0.0 to before 2.1.2, Rack::Session::Cookie incorrectly handles decryption failures when configured with secrets:. If cookie decryption fails, the implementation falls back to a default decoder instead of rejecting the cookie. This allows an unauthenticated attacker to supply a crafted session cookie that is accepted as valid session data without knowledge of any configured secret. Because this mechanism is used to load session state, an attacker can manipulate session contents and potentially gain unauthorized access. This vulnerability is fixed in 2.1.2. |
