Attackers can distribute skills with benign Python source files alongside malicious compiled bytecode that executes on import while the scanner reports a safe verdict, enabling code execution when operators install the skill.CVSS7.1HighEPSS0.57%PrioritiseCVE-2026-72565tencent · apijsonTencent APIJSON - Unauthenticated SQL Injection via @having Operator Map-Form BypassA SQL injection vulnerability in Tencent APIJSON through 8.1.8 allows unauthenticated remote attackers to bypass per-table access control and read arbitrary database tables via the Map-form @having operator.CVSS9.8CriticalEPSS0.68%RoutineCVE-2026-50144tencent · ncnnncnn: Out-of-bounds heap write in ParamDict::load_param via unchecked negative parameter idncnn is a high-performance neural network inference framework optimized for the mobile platform. In commit e54f7b1f88434e1d844ea0551b880a1cfb079ce1 and earlier, ncnn allows an out-of-bounds heap write in ncnn::ParamDict::load_param() when Net::load_param() loads a malicious .param model file because the parsed parameter id is checked only against id >= NCNN_MAX_PARAM_COUNT, allowing a negative id to index before the params[NCNN_MAX_PARAM_COUNT] array. This vulnerability is fixed by commit 5a0288f255daa6c3294f77109f67718e434ec020.CVSS7.1HighEPSS0.16%PrioritiseCVE-2026-15515tencent · pc managerTencent PC Manager QMUDisk Driver qmudisk64.sys uncontrolled search pathA security vulnerability has been detected in Tencent PC Manager 18.1.30242.301.

From version 0.2.5 to before version 0.2.10, an unauthenticated remote code execution (RCE) vulnerability exists in the MCP stdio configuration validation. The application allows unrestricted user registration, meaning any attacker can create an account and exploit the command injection flaw. Despite implementing a whitelist for allowed commands (npx, uvx) and blacklists for dangerous arguments and environment variables, the validation can be bypassed using the -p flag with npx node. This allows any attacker to execute arbitrary commands with the application's privileges, leading to complete system compromise. This issue has been patched in version 0.2.10.CVSS10.0CriticalEPSS2.38%PrioritiseCVE-2026-30860tencent · weknora +1 moreWeKnora: Remote Code Execution via SQL Injection Bypass in AI Database Query ToolWeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, a remote code execution (RCE) vulnerability exists in the application's database query functionality. The validation system fails to recursively inspect child nodes within PostgreSQL array expressions and row expressions, allowing attackers to bypass SQL injection protections. By smuggling dangerous PostgreSQL functions inside these expressions and chaining them with large object operations and library loading capabilities, an unauthenticated attacker can achieve arbitrary code execution on the database server with database user privileges. This issue has been patched in version 0.2.12.CVSS10.0CriticalEPSS0.73%RoutineCVE-2026-30859tencent · weknora +1 moreWeKnora: Broken Access Control - Cross-Tenant Data ExposureWeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, a broken access control vulnerability in the database query tool allows any authenticated tenant to read sensitive data belonging to other tenants, including API keys, model configurations, and private messages. The application fails to enforce tenant isolation on critical tables (models, messages, embeddings), enabling unauthorized cross-tenant data access with user-level authentication privileges. This issue has been patched in version 0.2.12.CVSS6.5MediumEPSS0.24%RoutineCVE-2026-30858tencent · weknora +1 moreWeKnora: DNS Rebinding Vulnerability in web_fetch Tool Allows SSRF to Internal ResourcesWeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.0, a DNS rebinding vulnerability in the web_fetch tool allows an unauthenticated attacker to bypass URL validation and access internal resources on the server, including private IP addresses (e.g., 127.0.0.1, 192.168.x.x). By crafting a malicious domain that resolves to a public IP during validation and subsequently resolves to a private IP during execution, an attacker can access sensitive local services and potentially exfiltrate data. This issue has been patched in version 0.3.0.CVSS7.5HighEPSS0.41%RoutineCVE-2026-30857tencent · weknora +1 moreWeKnora: Unauthorized Cross‑Tenant Knowledge Base CloningWeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.0, a cross-tenant authorization bypass in the knowledge base copy endpoint allows any authenticated user to clone (duplicate) another tenant’s knowledge base into their own tenant by knowing/guessing the source knowledge base ID. This enables bulk data exfiltration (document/FAQ content) across tenants. This issue has been patched in version 0.3.0.CVSS5.3MediumEPSS0.26%
