Overview CVE-2025-66414 identifies a security vulnerability in the Model Context Protocol (MCP) TypeScript SDK, the official TypeScript SDK for MCP servers and clients. Specifically, prior to version 1.24.0, the SDK does not enable DNS rebinding protection by default for HTTP-based servers. This can expose users to potential attacks when running an HTTP-based MCP server on localhost without authentication. Technical Details The vulnerability arises because the MCP TypeScript SDK, when configured to run an HTTP-based server (using StreamableHTTPServerTransport or SSEServerTransport) on localhost without authentication, doesn’t automatically enable DNS rebinding protection. DNS rebinding is a technique where a malicious website manipulates DNS…

This article provides a detailed analysis of CVE-2025-66409, a security vulnerability affecting Espressif’s ESP-IDF (IoT Development Framework). This vulnerability, if exploited, could lead to an out-of-bounds read, potentially exposing sensitive information or causing unexpected behavior on ESP32 devices. Overview CVE-2025-66409 is an out-of-bounds read vulnerability discovered in the ESP-IDF Bluetooth stack. Specifically, when AVRCP (Audio/Video Remote Control Profile) is enabled, a malformed VENDOR DEPENDENT command received from a paired Bluetooth device can cause the stack to access memory locations beyond the boundaries of the allocated buffer. This can occur because the command buffer length is not properly validated before memory…

Overview A significant SQL injection vulnerability, identified as CVE-2025-65896, has been discovered in the long2ice asyncmy library, specifically affecting versions up to and including 0.2.10. This flaw allows malicious actors to inject and execute arbitrary SQL commands through carefully crafted dictionary keys, potentially leading to severe data breaches and system compromise. Technical Details The vulnerability resides in how the asyncmy library processes dictionary keys when constructing SQL queries. By manipulating these keys, an attacker can inject malicious SQL code that bypasses intended sanitization and is then executed directly against the database. This can occur wherever the library constructs SQL statements…

Overview CVE-2025-61729 describes a vulnerability found within the HostnameError.Error() function in the Go programming language. The vulnerability stems from the unbounded inclusion of hostnames within the error string construction, combined with the use of repeated string concatenation. This can lead to excessive resource consumption, potentially resulting in a Denial-of-Service (DoS) attack if a malicious actor provides a crafted certificate. Technical Details The core of the vulnerability lies in how the HostnameError.Error() function constructs its error message. Specifically, the function iterates through a list of hostnames without a limit and appends them to the error string. Moreover, the implementation uses repeated…

Overview A critical security vulnerability, identified as CVE-2025-60736, has been discovered in version 1.0 of the Online Medicine Guide. This vulnerability allows for SQL Injection in the /login.php script, specifically through the upass parameter. This flaw could potentially allow attackers to bypass authentication, extract sensitive data, or even modify the database. Technical Details The vulnerability resides in the login.php script of the Online Medicine Guide 1.0 application. The upass parameter, used for handling user passwords during the login process, is susceptible to SQL Injection. Insufficient input validation and sanitization of the upass parameter allows an attacker to inject malicious SQL…

Overview CVE-2025-57850 is a medium-severity container privilege escalation vulnerability affecting certain CodeReady Workspaces images. This flaw allows a non-root user within an affected container to potentially gain root privileges. This is achieved by exploiting insecure file permissions on the /etc/passwd file, which is writable by the root group. Technical Details The vulnerability arises because the /etc/passwd file within the affected CodeReady Workspaces container images is created with group-writable permissions during the image build process. While containers are designed to provide isolation, this specific configuration allows users who are members of the root group (which might be more permissive than intended…

Overview CVE-2025-34352 details a critical vulnerability affecting JumpCloud Remote Assist for Windows versions prior to 0.317.0. This flaw allows a local, low-privileged attacker to potentially escalate their privileges to SYSTEM, the highest level of privilege on a Windows system. This is achieved by exploiting insecure handling of temporary directories during the uninstallation or update process of Remote Assist. The vulnerability arises from predictable file paths created in a user-writable `%TEMP%` directory. Technical Details The JumpCloud Windows Agent invokes the Remote Assist uninstaller with NT AUTHORITY\SYSTEM privileges during uninstall or update operations. The vulnerable uninstaller performs privileged operations (create, write, execute,…

Overview CVE-2025-13721 is a security vulnerability discovered in the v8 JavaScript engine of Google Chrome. Specifically, a race condition exists that, if successfully exploited, could allow a remote attacker to cause heap corruption. This vulnerability affects Google Chrome versions prior to 143.0.7499.41. Google has classified this vulnerability as having a “Medium” severity (Chromium security severity: Medium). Technical Details The vulnerability stems from a race condition within the v8 JavaScript engine. Race conditions occur when multiple threads or processes access and manipulate shared data concurrently, and the outcome of the execution depends on the particular order in which the access takes…

Overview CVE-2025-13720 is a medium severity vulnerability affecting Google Chrome versions prior to 143.0.7499.41. This flaw stems from a bad cast within the Loader component of Chrome. A remote attacker who has successfully compromised the renderer process could potentially leverage this vulnerability to exploit heap corruption by crafting a malicious HTML page. This could lead to arbitrary code execution within the context of the renderer process. Technical Details The vulnerability resides in the Loader component of Google Chrome. A “bad cast” error occurs when the code attempts to treat an object of one type as if it were an object…

Overview CVE-2025-13639 is a security vulnerability affecting Google Chrome’s WebRTC (Web Real-Time Communication) implementation. This flaw, reported on December 2nd, 2025, could be exploited by a remote attacker to perform arbitrary read/write operations on a user’s system. The vulnerability stems from an inappropriate implementation within WebRTC in Google Chrome versions prior to 143.0.7499.41. While the Chromium security team has classified this as a “Low” severity issue, it’s crucial to understand the potential impact and take appropriate mitigation steps. Technical Details The specific nature of the “inappropriate implementation” within WebRTC isn’t fully disclosed in the public advisories. However, the description indicates…
