Vulnerability Watch No57

⚠️ Monkeytype Rate Limit Bypass Enables Abuse
Monkeytype operators should review exposed deployments and patch when a fixed version is available. Prioritize instances with public signup or email workflows because attackers can abuse this flaw for mail bombing, quota consumption, and brute-force protection bypass.
CVE-2026-69183 affects Monkeytype 26.26.0 and earlier, where backend rate-limit key generation trusts client-controlled headers instead of trusted proxy-derived values. The vulnerability has CVSS 7.5 and HIGH severity, allowing unauthenticated attackers to bypass request throttling, abuse account recovery endpoints, and cause resource exhaustion.

🛡️ Plate DOCX Conversion Flaw Exposes Internal Services
Applications using Plate document conversion with untrusted HTML should upgrade to 53.3.2 immediately. Teams running server-side DOCX generation should treat these services as exposed because attackers may reach internal resources through crafted remote URLs.
CVE-2026-65842 affects Plate versions prior to 53.3.2 through the @platejs/docx-io HTML to DOCX conversion process that fetches remote images. The vulnerability has CVSS 8.2 and HIGH severity, enabling server-side request forgery with response disclosure and possible resource consumption.

🌐 Link Preview JS DNS Rebinding Bypasses SSRF Protection
Upgrade Link Preview JS to 4.0.4 and review any preview services that process user-controlled URLs. This is especially urgent for internet-facing applications because attackers can use crafted domains to reach protected internal services.
CVE-2026-61704 affects Link Preview JS versions prior to 4.0.4, where DNS validation can be bypassed because the validated address differs from the final fetched hostname. The vulnerability has CVSS 7.5 and HIGH severity, allowing attackers to bypass SSRF defenses and access internal HTTP resources.

🚨 dbx Authentication Bypass Enables Database Takeover
Patch dbx to version 0.5.51 immediately and verify DBX_PASSWORD settings on all deployments. Internet-exposed instances are the highest priority because attackers may read, alter, or destroy data in connected databases.
CVE-2026-55642 affects dbx prior to 0.5.51, where missing password configuration can allow protected API routes to proceed without authentication. The vulnerability has CVSS 9.8 and CRITICAL severity, allowing unauthenticated network attackers to use configured database credentials and execute arbitrary SQL.

📦 NanaZip Archive Parsing Bug Risks Data Exposure
NanaZip users should install stable version 6.0.1698.0 or preview version 6.5.1742.0 and avoid opening untrusted archives until updated. Prioritize workstations that regularly process downloaded files.
CVE-2026-54616 affects NanaZip versions from 1.0.88.0 through stable version 6.0.1698.0 and preview version 6.5.1742.0 due to improper Lz4Decode error handling. The vulnerability has CVSS 7.1 and HIGH severity, potentially allowing heap data disclosure or crashes through crafted archives.

🤖 LangBot MCP Configuration Flaw Enables Commands
LangBot administrators should patch when a fixed version is available and restrict account creation and extension configuration access. Review MCP configurations now for unauthorized command settings because any user account may be able to trigger server-side execution.
CVE-2026-54449 affects LangBot 4.10.7 and earlier, where authenticated users can change STDIO MCP server configurations without proper authorization controls. The vulnerability has CVSS 8.8 and HIGH severity, allowing command execution with the privileges of the LangBot service.

🔄 deepmerge-ts Recursion Bug Can Crash Applications
Developers using deepmerge-ts with untrusted object data should upgrade to version 8.0.0. Services handling complex user input should prioritize this dependency update because crafted objects can crash application workers.
CVE-2026-40345 affects deepmerge-ts versions prior to 8.0.0, where recursive object merging can repeatedly process self-referencing object structures. The vulnerability has CVSS 8.2 and HIGH severity, allowing denial of service through attacker-controlled recursive object graphs.
