| CVE-2026-3192 | Med | 0.36 | 5.6 | 0.00 | Feb 25, 2026 | A security vulnerability has been detected in Chia Blockchain 2.1.0. This issue affects the function _authenticate of the file rpc_server_base.py of the component RPC Credential Handler. The manipulation leads to improper authentication. The attack is possible to be carried out remotely. The attack is considered to have high complexity. The exploitability is assessed as difficult. The exploit has been disclosed publicly and may be used. The vendor was informed early via email. A separate report via bugbounty was rejected with the reason "This is by design. The user is responsible for host security". | |
| CVE-2026-20655 | Med | 0.36 | 5.5 | 0.00 | Feb 11, 2026 | An authorization issue was addressed with improved state management. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3. An attacker with physical access to a locked device may be able to view sensitive user information. | |
| CVE-2026-1203 | Med | 0.36 | 5.6 | 0.00 | Jan 20, 2026 | A weakness has been identified in CRMEB up to 5.6.3. The impacted element is the function remoteRegister of the file crmeb/app/services/user/LoginServices.php of the component JSON Token Handler. Executing a manipulation of the argument uid can lead to improper authentication. The attack may be performed from remote. The attack requires a high level of complexity.

This vulnerability allows users whose AD accounts are expired or disabled to regain access in Keycloak, bypassing AD restrictions. The issue enables authentication bypass and could allow unauthorized access under certain conditions. | |
| CVE-2024-10511 | Med | 0.35 | 5.3 | 0.01 | Dec 11, 2024 | CWE-287: Improper Authentication vulnerability exists that could cause Denial of access to the web interface when someone on the local network repeatedly requests the /accessdenied URL. | |
| CVE-2020-26139 | Med | 0.35 | 5.3 | 0.02 | May 11, 2021 | An issue was discovered in the kernel in NetBSD 7.1.

This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients. | |
| CVE-2017-6871 | Med | 0.35 | 5.4 | 0.00 | Aug 8, 2017 | A vulnerability was discovered in Siemens SIMATIC WinCC Sm@rtClient for Android (All versions before V1.0.2.2) and SIMATIC WinCC Sm@rtClient for Android Lite (All versions before V1.0.2.2). An attacker with physical access to an unlocked mobile device, that has the affected app running, could bypass the app's authentication mechanism under certain conditions. | |
| CVE-2017-6617 | Med | 0.35 | 5.4 | 0.00 | Apr 20, 2017 | A vulnerability in the session identification management functionality of the web-based GUI of Cisco Integrated Management Controller (IMC) 3.0(1c) could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system. The vulnerability exists because the affected software does not assign a new session identifier to a user session when a user authenticates to the web-based GUI. An attacker could exploit this vulnerability by using a hijacked session identifier to connect to the software through the web-based GUI. A successful exploit could allow the attacker to hijack an authenticated user's browser session on the affected system. Cisco Bug IDs: CSCvd14583. | |
