Overview This article provides a detailed analysis of CVE-2025-13086, a security vulnerability affecting OpenVPN versions 2.6.0 through 2.7_rc1. This vulnerability stems from improper validation of source IP addresses during session establishment, potentially allowing an attacker to hijack existing sessions and cause a denial of service (DoS) for legitimate clients. Technical Details The core issue lies in the inadequate verification of the source IP address of incoming packets after the initial connection handshake. An attacker, by spoofing the IP address of a connected client, can inject packets into the existing OpenVPN session. This allows them to effectively take over the session…

Overview CVE-2025-12385 identifies a vulnerability within the Text component of the Qt Quick framework. This vulnerability stems from the lack of proper validation for the width and height attributes within the <img> tag. An attacker can exploit this by injecting excessively large values into these attributes, causing the application to allocate an unreasonable amount of resources, potentially leading to unresponsiveness or a denial-of-service (DoS) condition. This vulnerability affects Qt versions 5.0.0 through 6.5.10, 6.6.0 through 6.8.5, and 6.9.0 through 6.10.0 across multiple platforms including Windows, MacOS, Linux, iOS, and Android, as well as architectures like x86, ARM, 64-bit, and 32-bit.…

Overview CVE-2025-66222 is a critical security vulnerability affecting DeepChat, a smart assistant powered by artificial intelligence. Specifically, versions 0.5.0 and earlier are susceptible to a Stored Cross-Site Scripting (XSS) vulnerability within the Mermaid diagram rendering functionality. This flaw allows a malicious actor to inject and execute arbitrary JavaScript code within the context of the DeepChat application. More alarmingly, this XSS vulnerability can be escalated to Remote Code Execution (RCE) by exploiting the exposed Electron IPC bridge. Technical Details The vulnerability resides in how DeepChat handles Mermaid diagrams. An attacker can craft a malicious Mermaid diagram containing JavaScript code. When a…

Overview CVE-2025-66220 describes a medium severity vulnerability affecting Envoy, a high-performance edge/middle/service proxy. This vulnerability resides in the mTLS certificate matching logic when using match_typed_subject_alt_names. Specifically, certificates containing an embedded null byte (\0) within an OTHERNAME Subject Alternative Name (SAN) value can be incorrectly treated as valid matches, potentially leading to an mTLS bypass. This affects Envoy versions 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier. Technical Details The vulnerability stems from how Envoy parses and validates the OTHERNAME SAN values in client certificates during mTLS authentication. The match_typed_subject_alt_names feature allows Envoy to match specific SAN values against a configured list. However,…

Overview A critical vulnerability, identified as CVE-2025-66208, has been discovered in Collabora Online’s Built-in CODE Server (richdocumentscode). This vulnerability, affecting versions prior to 25.04.702, allows for Configuration-Dependent Remote Code Execution (RCE) via OS Command Injection within the richdocumentscode proxy. Specifically, users leveraging the Nextcloud Collabora Online – Built-in CODE Server app are susceptible to attack through the `proxy.php` file and an intermediate reverse proxy. Technical Details The vulnerability stems from insufficient sanitization of input passed to the `proxy.php` script within the Collabora Online Built-in CODE Server. An attacker can exploit this weakness by crafting malicious requests that, when processed by…

Overview CVE-2025-63402 describes a medium severity vulnerability affecting HCL Technologies Limited’s HCLTech GRAGON product. Specifically, versions prior to 7.6.0 are susceptible to remote code execution (RCE). This vulnerability stems from a lack of input validation on API endpoints, allowing attackers to potentially overwhelm the system and execute arbitrary code. Technical Details The vulnerability lies in the improper handling of requests made to GRAGON’s APIs. The affected APIs do not enforce limits on either the number of requests made within a specific timeframe or the size of individual requests. An attacker could exploit this by sending a large volume of excessively…

Overview CVE-2025-63401 is a Cross-Site Scripting (XSS) vulnerability identified in HCL Technologies Limited’s HCLTech DRAGON software, affecting versions prior to 7.6.0. This vulnerability allows a remote attacker to execute arbitrary code within the context of a user’s browser session. The root cause lies in missing directives that fail to properly sanitize user-supplied input, opening a door for malicious script injection. Technical Details The vulnerability stems from insufficient input validation within the HCLTech DRAGON application. Specifically, certain user-supplied data is not properly sanitized or encoded before being rendered in a web page. An attacker can exploit this by injecting malicious JavaScript…

Overview CVE-2025-50360 describes a critical heap buffer overflow vulnerability discovered in the Pepper language version 0.1.1, specifically within the compiler.c and compiler.h files at commit 961a5d9988c5986d563310275adad3fd181b2bb7. This flaw could be exploited by a malicious actor through the execution of a crafted Pepper source file (.pr), potentially leading to arbitrary code execution or a denial-of-service (DoS) condition. Technical Details The vulnerability resides in how the Pepper language compiler handles certain input within source files. A specifically crafted .pr file, when compiled, can cause the compiler to write data beyond the allocated boundaries of a heap buffer. This out-of-bounds write can overwrite…

Overview CVE-2025-33211 is a high-severity vulnerability affecting NVIDIA Triton Server for Linux. This vulnerability stems from improper validation of specified quantity in input, potentially allowing an attacker to trigger a denial-of-service (DoS) condition. This article provides a comprehensive analysis of the vulnerability, including technical details, CVSS score breakdown, potential impact, and mitigation strategies. Technical Details The vulnerability resides in the handling of input quantities within NVIDIA Triton Server. Specifically, the server fails to adequately validate the specified quantity of certain input parameters. An attacker can exploit this flaw by crafting malicious input that bypasses the validation checks. This leads to…
