| CVE-2025-31496 | 2026-04-15 | 7.5 High | ||
| apollo-compiler is a query-based compiler for the GraphQL query language. Prior to 1.27.0, a vulnerability in Apollo Compiler allowed queries with deeply nested and reused named fragments to be prohibitively expensive to validate. Named fragments were being processed once per fragment spread in some cases during query validation, leading to exponential resource usage when deeply nested and reused fragments were involved. This could lead to excessive resource consumption and denial of service in applications. This vulnerability is fixed in 1.27.0. | ||||
| CVE-2025-32032 | 2026-04-15 | 7.5 High | ||
| The Apollo Router Core is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation 2. A vulnerability in Apollo Router allowed queries with deeply nested and reused named fragments to be prohibitively expensive to query plan, specifically due to internal optimizations being frequently bypassed. The query planner includes an optimization that significantly speeds up planning for applicable GraphQL selections. However, queries with deeply nested and reused named fragments can generate many selections where this optimization does not apply, leading to significantly longer planning times. Because the query planner does not enforce a timeout, a small number of such queries can exhaust router's thread pool, rendering it inoperable. This could lead to excessive resource consumption and denial of service. This has been remediated in apollo-router versions 1.61.2 and 2.1.1. | ||||

| CVE-2020-37134 | 1 Ultravnc | 2 Ultravnc, Vnc Viewer | 2026-04-15 | 7.5 High |
| UltraVNC Viewer 1.2.4.0 contains a denial of service vulnerability that allows attackers to crash the application by manipulating VNC Server input. Attackers can generate a malformed 256-byte payload and paste it into the VNC Server connection dialog to trigger an application crash. | ||||
| CVE-2024-6098 | 2026-04-15 | 5.3 Medium | ||
| When performing an online tag generation to devices which communicate using the ControlLogix protocol, a machine-in-the-middle, or a device that is not configured correctly, could deliver a response leading to unrestricted or unregulated resource allocation. This could cause a denial-of-service condition and crash the Kepware application. By default, these functions are turned off, yet they remain accessible for users who recognize and require their advantages. | ||||

| AgataSoft PingMaster Pro 2.1 contains a denial of service vulnerability in the Trace Route feature that allows attackers to crash the application by overflowing the host name input field. Attackers can generate a 10,000-character buffer and paste it into the host name field to trigger an application crash and potential system instability. | ||||
| CVE-2025-15474 | 1 Auntyfey | 1 Smart Combination Lock | 2026-04-15 | N/A |
| AuntyFey Smart Combination Lock firmware versions as of 2025-12-24 contain a vulnerability that allows an unauthenticated attacker within Bluetooth Low Energy (BLE) range to cause a denial of service by repeatedly initiating BLE connections. Sustained connection attempts interrupt keypad authentication input and repeatedly force the device into lockout states, preventing legitimate users from unlocking the device. | ||||
| CVE-2025-45526 | 2026-04-15 | 2.9 Low | ||
| A denial of service (DoS) vulnerability has been identified in the JavaScript library microlight version 0.0.7. This library, used for syntax highlighting, does not limit the size of textual content it processes in HTML elements with the microlight class. When excessively large content (e.g., 100 million characters) is processed, the reset function in microlight.js consumes excessive memory and CPU resources, causing browser crashes or unresponsiveness. An attacker can exploit this vulnerability by tricking a user into visiting a malicious web page containing a microlight element with large content, resulting in a denial of service. NOTE: this is disputed by multiple parties because a large amount of memory and CPU resources is expected to be needed for content of that size. | ||||
| CVE-2024-23185 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 7.5 High |
| Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "full_value" buffer out of the smaller chunks. The full_value buffer has no size limit, so large headers can cause large memory usage. It doesn't matter whether it's a single long header line, or a single header split into multiple lines. This bug exists in all Dovecot versions. Incoming mails typically have some size limits set by MTA, so even largest possible header size may still fit into Dovecot's vsz_limit. So attackers probably can't DoS a victim user this way. A user could APPEND larger mails though, allowing them to DoS themselves (although maybe cause some memory issues for the backend in general). One can implement restrictions on headers on MTA component preceding Dovecot. No publicly available exploits are known. | ||||
| CVE-2025-31990 | 1 Hclsoftware | 1 Hcl Devops Velocity | 2026-04-15 | 6.8 Medium |
| Rate limiting for certain API calls is not being enforced, making HCL Velocity vulnerable to Denial of Service (DoS) attacks. An attacker could flood the system with a large number of requests, overwhelming its resources and causing it to become unresponsive to legitimate users. This vulnerability is fixed in 5.1.7. | ||||
| CVE-2020-37085 | 1 Sunnysidesoft | 1 Virtualtablet Server | 2026-04-15 | 7.5 High |
| VirtualTablet Server 3.0.2 contains a denial of service vulnerability that allows attackers to crash the service by sending oversized string payloads through the Thrift protocol. Attackers can exploit the vulnerability by sending a long string to the send_say() method, causing the server to become unresponsive. | ||||
| CVE-2025-22273 | 1 Cyberark | 1 Endpoint Privilege Manager | 2026-04-15 | N/A |
| Application does not limit the number or frequency of user interactions, such as the number of incoming requests. At the "/EPMUI/VfManager.asmx/ChangePassword" endpoint it is possible to perform a brute force attack on the current password in use.
