TP-Link Archer NX Router Vulnerabilities (Multiple CVEs)

TP-Link disclosed multiple high-severity vulnerabilities (CVE-2025-15517, CVE-2025-15518, CVE-2025-15519, CVE-2025-15605) affecting Archer NX series routers (NX200, NX210, NX500, NX600), enabling authentication bypass, command injection, and configuration decryption.

Attackers can exploit these flaws to gain unauthorized administrative access, execute arbitrary commands, and decrypt or tamper with router configurations, potentially leading to full device compromise, remote code execution, credential exposure, and network-wide attacks such as MITM.

TP-Link has released firmware updates to address these issues. Users are strongly advised to update immediately, restrict admin access, disable unnecessary remote management, enforce strong credentials, and monitor for suspicious activity to reduce risk.

NVIDIA AI Frameworks Vulnerabilities (Multiple CVEs)

NVIDIA disclosed multiple vulnerabilities across its AI ecosystem (including Apex, Triton Inference Server, NeMo, and Megatron-LM), with one critical flaw (CVE-2025-33244, CVSS 9.8) enabling remote code execution and several others allowing DoS and privilege escalation.

These vulnerabilities can compromise AI training and inference environments, leading to model theft, data exposure, service disruption, and unauthorized control over ML pipelines.

Organizations should urgently apply NVIDIA’s March 2026 patches, restrict access to AI systems, enforce least-privilege controls, and monitor workloads to mitigate risks and prevent potential exploitation.

Node.js Vulnerabilities (Multiple CVEs)

Node.js released security updates on March 24, 2026, for versions 20.x, 22.x, 24.x, and 25.x, addressing high-severity flaws like CVE-2026-21637 and CVE-2026-21710 that enable DoS via uncaught exceptions in TLS and HTTP processing, plus permission bypasses and side-channel attacks.

These issues allow attackers to crash processes, evade filesystem/network restrictions (e.g., via Unix Domain Sockets or crafted headers), cause memory leaks, HashDoS in V8, and leak info through cryptographic timing flaws.

Upgrade immediately to Node.js 20.20.2, 22.22.2, 24.14.1, or 25.8.2; validate inputs, use safe error handling, review permission models, and monitor for crashes or resource spikes.

Claude Chrome Extension Zero-Click Vulnerability

Researchers uncovered a critical zero-click flaw in the Claude Chrome Extension, exposing over 3 million users to silent prompt injection attacks via malicious websites.

Attackers exploited permissive subdomain trust on *.claude.ai and a DOM-based XSS in Arkose Labs CAPTCHA scripts to hijack Claude, enabling unauthorized access to Gmail, Google Drive, OAuth tokens, chat histories, and email sending without user interaction.

Anthropic patched it in January/February 2026 (update to v1.0.41+); the incident underscores risks in AI browser agents from broad trust models and third-party components.
