Skyvern versions through 0.1.85 contain a server-side template injection (SSTI) vulnerability in the Prompt field of workflow blocks (specifically Navigation v2 Block) that allows authenticated users to inject malicious Jinja2 template expressions. These expressions are evaluated server-side without proper sanitization, enabling blind remote code execution. With a CVSS score of 8.5, this vulnerability requires valid authentication but has high confidentiality impact and crosses trust boundaries (CVSS:3.1/S:C).
A critical buffer overflow vulnerability exists in Tenda AC9 router firmware version 15.03.02.13, affecting the POST request handler for LAN IP configuration. An authenticated attacker can exploit the lanMask parameter in the /goform/AdvSetLanip endpoint to trigger a buffer overflow, achieving remote code execution with full system compromise (confidentiality, integrity, and availability impact). Public exploit code is available and the vulnerability is actively exploitable with authenticated access.
Denial of Service vulnerability in libcurl's WebSocket implementation that allows a malicious server to send a specially crafted packet triggering an endless busy-loop, forcing applications to kill the affected thread or process to recover. This affects all libcurl versions with WebSocket support, with CVSS 7.5 (High) severity due to network-accessible attack vector requiring no authentication. The vulnerability has high real-world impact for any application using libcurl for WebSocket connections, though exploitation requires active malicious server control.
Critical unrestricted file upload vulnerability in SourceCodester Client Database Management System 1.0, affecting the /user_update_customer_order.php endpoint. An unauthenticated remote attacker can upload arbitrary files by manipulating the 'uploaded_file' parameter, potentially leading to remote code execution, data integrity compromise, and service disruption. The vulnerability has a CVSS 7.3 score and poses moderate-to-high real-world risk given the unauthenticated attack vector and low complexity.
Missing authorization vulnerability in Christiaan Pieterse MaxiBlocks WordPress plugin (versions up to 2.1.0) that allows authenticated users with low privileges to escalate their access and perform unauthorized actions with high impact. An attacker with basic user credentials can bypass authorization checks to modify content, user accounts, or plugin settings, potentially leading to complete site compromise. The high CVSS score of 8.8 reflects the severe impact, though exploitation requires prior authentication access.
A cross-site scripting vulnerability in all (CVSS 7.2). High severity vulnerability requiring prompt remediation.
