| CVE-2026-41081 | Med | 0.42 | 6.5 | 0.00 | Apr 27, 2026 | Improper Handling of TLS Client Authentication Failure Leading to Anonymous Principal Assignment in Apache Storm Versions Affected: up to 2.8.7 Description: When TLS transport is enabled in Apache Storm without requiring client certificate authentication (the default configuration), the TlsTransportPlugin assigns a fallback principal (CN=ANONYMOUS) if no client certificate is presented or if certificate verification fails. The underlying SSLPeerUnverifiedException is caught and suppressed rather than rejecting the connection. This fail-open behavior means an unauthenticated client can establish a TLS connection and receive a valid principal identity. If the configured authorizer (e.g., SimpleACLAuthorizer) does not explicitly deny access to CN=ANONYMOUS, this may result in unauthorized access to Storm services. The condition is logged at debug level only, reducing visibility in production. Impact: Unauthenticated clients may be assigned a principal identity, potentially bypassing authorization in permissive or misconfigured environments. Mitigation: Users should upgrade to 2.8.7 in which TLS authentication failures are handled in a fail-closed manner. Users who cannot upgrade immediately should: - Enable mandatory client certificate authentication (nimbus.thrift.tls.client.auth.required: true) - Ensure authorization rules explicitly deny access to CN=ANONYMOUS - Review all ACL configurations for implicit default-allow behavior | |
| CVE-2026-40910 | Med | 0.42 | 6.5 | 0.00 | Apr 21, 2026 | frp is a fast reverse proxy. From 0.43.0 to 0.68.0, frp contains an authentication bypass in the HTTP vhost routing path when routeByHTTPUser is used as part of access control. In proxy-style requests, the routing logic uses the username from Proxy-Authorization to select the routeByHTTPUser backend, while the access control check uses credentials from the regular Authorization header. As a result, an attacker who can reach the HTTP vhost entrypoint and knows or can guess the protected routeByHTTPUser value may access a backend protected by httpUser / httpPassword even with an incorrect Proxy-Authorization password. This issue affects deployments that explicitly use routeByHTTPUser. It does not affect ordinary HTTP proxies that do not use this feature. This vulnerability is fixed in 0.68.1. | |
| CVE-2026-6588 | Med | 0.42 | 6.5 | 0.00 | Apr 20, 2026 | A weakness has been identified in serge-chat serge up to 1.4TB. The impacted element is the function download_model/delete_model of the file api/src/serge/routers/model.py of the component Model API Endpoint. Executing a manipulation can lead to missing authentication. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2026-6579 | Med | 0.42 | 6.5 | 0.00 | Apr 19, 2026 | A weakness has been identified in liangliangyy DjangoBlog up to 2.1.0.0. This impacts an unknown function of the file blog/views.py of the component Clean Endpoint. This manipulation causes missing authentication. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. | |

This issue affects Apache Tomcat: from 11.0.0-M14 through 11.0.20, from 10.1.22 through 10.1.53, from 9.0.92 through 9.0.116. Users are recommended to upgrade to version 11.0.21, 10.1.54 or 9.0.117, which fixes the issue. | |
| CVE-2026-34531 | Med | 0.42 | 6.5 | 0.00 | Apr 1, 2026 | Flask-HTTPAuth provides Basic, Digest and Token HTTP authentication for Flask routes. Prior to version 4.8.1, in a situation where the client makes a request to a token protected resource without passing a token, or passing an empty token, Flask-HTTPAuth would invoke the application's token verification callback function with the token argument set to an empty string. If the application had any users in its database with an empty string set as their token, then it could potentially authenticate the client request against any of those users. This issue has been patched in version 4.8.1. | |
| CVE-2026-34389 | Med | 0.42 | 6.5 | 0.00 | Mar 27, 2026 | Fleet is open source device management software. Prior to 4.81.0, Fleet contained an issue in the user invitation flow where the email address provided during invite acceptance was not validated against the email address associated with the invite. An attacker who obtained a valid invite token could create an account under an arbitrary email address while inheriting the role granted by the invite, including global admin. Version 4.81.0 patches the issue. | |

The manipulation results in missing authentication. An attack on the physical device is feasible. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2025-15455 | Med | 0.42 | 6.5 | 0.00 | Jan 5, 2026 | A flaw has been found in bg5sbk MiniCMS up to 1.8. Impacted is the function delete_page of the file /minicms/mc-admin/page.php of the component File Recovery Request Handler. This manipulation causes improper authentication. The attack is possible to be carried out remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2025-54376 | Hig | 0.42 | 7.5 | 0.00 | Sep 10, 2025 | Hoverfly is an open source API simulation tool. In versions 1.11.3 and prior, Hoverfly’s admin WebSocket endpoint /api/v2/ws/logs is not protected by the same authentication middleware that guards the REST admin API. Consequently, an unauthenticated remote attacker can stream real-time application logs (information disclosure) and/or gain insight into internal file paths, request/response bodies, and other potentially sensitive data emitted in logs. Version 1.12.0 contains a fix for the issue. | |
| CVE-2025-30432 | Med | 0.42 | 6.4 | 0.00 | Mar 31, 2025 | A logic issue was addressed with improved state management. This issue is fixed in iOS 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, visionOS 2.4, watchOS 11.4. A malicious app may be able to attempt passcode entries on a locked device and thereby cause escalating time delays after 4 failures. |
