revera 1.0.0 Released: npm Package Security CLI
Aarav Maloo announced the release of revera@1.0.0, an open-source CLI that scores npm packages for security risk prior to installation. The 1.0.0 rewrite replaces fixed weights with a Bayesian evidence engine: each package is modeled as a node in its dependency graph, scored across eight categories using signals such as vulnerability feeds, publisher trust, GitHub activity, and typosquat detection, with risk propagated bottom-up through the entire dependency tree. The post was published on 2026-07-18 and includes the install command 'npm install revera'.
Open-source developer security tool release relevant to software supply-chain security; useful to developers but has limited direct impact on the broader AdTech/MarTech industry.

Scan Finds Critical Vulnerabilities in 402 MCP npm Packages
A security researcher audited 2,386 Model Context Protocol (MCP) packages on the npm registry using a static-analysis scanner and an open detection standard called ATR (Agent Threat Rules). The scan extracted 35,858 tool definitions and found security findings in 49% of packages: 402 rated CRITICAL and 240 HIGH. Issues included SSH key exfiltration, hidden prompt injection, delayed backdoors, environment-variable credential harvesting, and over‑privileged tools that auto-execute on install. The author published ATR (61 rules, 474 detection patterns) and the PanGuard scanner as MIT-licensed open source, reporting 99.4% precision and 39.9% recall for detections. Responsible disclosure was carried out for high-risk packages. The results highlight supply-chain and agent-threat risks for AI agent ecosystems that install MCP packages with broad system access.
3va: Rust-built JS/TS runtime with strict permissions
3va v2.0.2 is a JavaScript and TypeScript runtime implemented in Rust that enforces capability-based permissions by default. The runtime blocks filesystem, network, environment, child processes, and native addon access unless explicitly allowed, and it unconditionally prevents post-install scripts from running. 3va installs from standard registries (npm, Yarn, etc.), aims to be compatible with common frameworks (Next.js, React, Express, Fastify and others), and bundles a package manager, built-in process manager, test runner, bundler, DDoS protections, and post-quantum cryptography primitives. The author publishes benchmarks comparing 3va (debug build) with Node.js and Bun—acknowledging Bun’s superior raw throughput and startup—but emphasizes 3va’s security and permission isolation as its primary value. Multiple install channels are provided (npm, Homebrew, Chocolatey, Scoop, cargo, Flatpak).
144 Mastra npm Packages Compromised in Supply-Chain Attack
In June 2026, attackers hijacked an npm contributor account (ehindero) and mass-published malicious versions of 144 packages in the @mastra namespace in an incident dubbed the easy-day-js supply-chain attack. Security researchers from JFrog, SafeDep, Socket and StepSecurity jointly uncovered the breach. Mastra is a popular open-source JavaScript/TypeScript framework used for AI application development, so the compromise risks propagating malicious code into many downstream projects and AI workloads. Researchers recommend immediate automated dependency audits, removal or rollback of affected packages, credential rotation, enforcing multi-factor authentication for publishers, and continuous monitoring via supply-chain scanning tools (e.g., JFrog Xray, Socket, SafeDep). The incident underscores account-level contributor access as a major attack surface for npm and similar registries, and calls for stronger registry-level publisher controls and provenance checks.
