When the calendar module is enabled and an authenticated user has permission to access it, an attacker can inject and execute arbitrary PHP code. Successful exploitation leads to remote code execution in the context of the web server user. | |
| CVE-2025-34108 | Hig | 0.65 | — | 0.70 | Jul 15, 2025 | A stack-based buffer overflow vulnerability exists in the login functionality of Disk Pulse Enterprise version 9.0.34. An attacker can send a specially crafted HTTP POST request to the /login endpoint with an overly long username parameter, causing a buffer overflow in the libspp.dll component. Successful exploitation allows arbitrary code execution with SYSTEM privileges. | |
| CVE-2025-34060 | Cri | 0.65 | — | 0.02 | Jul 1, 2025 | A PHP objection injection vulnerability exists in the Monero Project’s Laravel-based forum software due to unsafe handling of untrusted input in the /get/image/ endpoint. The application passes a user-supplied link parameter directly to file_get_contents() without validation. MIME type checks using PHP’s finfo can be bypassed via crafted stream filter chains that prepend spoofed headers, allowing access to internal Laravel configuration files. An attacker can extract the APP_KEY from config/app.php, forge encrypted cookies, and trigger unsafe unserialize() calls, leading to reliable remote code execution. | |
| CVE-2025-34043 | Cri | 0.65 | — | 0.01 | Jun 26, 2025 | A remote command injection vulnerability exists in Vacron Network Video Recorder (NVR) devices v1.4 due to improper input sanitization in the board.cgi script.

These commands are executed with the privileges of the web server process, enabling remote code execution and potential full device compromise. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC. | |
| CVE-2023-41917 | Cri | 0.65 | 10.0 | 0.03 | Jul 2, 2024 | Inadequate input validation exposes the system to potential remote code execution (RCE) risks. Attackers can exploit this vulnerability by appending shell commands to the Speed-Measurement feature, enabling unauthorized code execution. | |
| CVE-2026-41268 | Cri | 0.64 | 9.8 | 0.01 | Apr 23, 2026 | Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, Flowise is vulnerable to a critical unauthenticated remote command execution (RCE) vulnerability. It can be exploited via a parameter override bypass using the FILE-STORAGE:: keyword combined with a NODE_OPTIONS environment variable injection. This allows for the execution of arbitrary system commands with root privileges within the containerized Flowise instance, requiring only a single HTTP request and no authentication or knowledge of the instance. This vulnerability is fixed in 3.1.0. | |
| CVE-2026-32604 | Cri | 0.64 | 9.9 | 0.00 | Apr 20, 2026 | Spinnaker is an open source, multi-cloud continuous delivery platform. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, a bad actor can execute arbitrary commands very simply on the clouddriver pods. This can expose credentials, remove files, or inject resources easily. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable the gitrepo artifact types. | |
| CVE-2026-35031 | Cri | 0.64 | 9.9 | 0.00 | Apr 14, 2026 | Jellyfin is an open source self hosted media server. Versions prior to 10.11.7 contain a vulnerability chain in the subtitle upload endpoint (POST /Videos/{itemId}/Subtitles), where the Format field is not validated, allowing path traversal via the file extension and enabling arbitrary file write. This arbitrary file write can be chained into arbitrary file read via .strm files, database extraction, admin privilege escalation, and ultimately remote code execution as root via ld.so.preload. Exploitation requires an administrator account or a user that has been explicitly granted the "Upload Subtitles" permission. This issue has been fixed in version 10.11.7. If users are unable to upgrade immediately, they can grant non-administrator users Subtitle upload permissions to reduce attack surface. | |
