CVE-2026-55637

genieacs-mcp is an MCP server for GenieACS written in Go. Prior to 0.3.2, the Streamable HTTP transport in cmd/server/main.go creates an unauthenticated /mcp listener on the default MCPLISTENADDR value 127.0.0.1:8080 when MCPAUTHTOKEN is unset and the httpSrv.Startaddr branch does not validate th...

GHSA-CMWV-WF9P-P8WX genieacs-mcp: DNS rebinding reaches local GenieACS MCP Streamable HTTP transport

genieacs-mcp exposes a local Streamable HTTP MCP endpoint that accepts attacker-controlled Host and Origin headers. A malicious web page can use DNS rebinding to route browser requests to a victim's loopback MCP listener while preserving the attacker origin. The server accepts the request,...

CVE-2026-55526 PraisonAI: SSRF protection bypass in `spider_tools._host_is_blocked()` via DNS-resolved hostnames (`127.0.0.1.nip.io`)

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, spidertools.hostisblocked does not resolve ordinary hostnames before scrapepage fetches them. A hostname such as 127.0.0.1.nip.io passes validation and resolves to loopback, permitting internal HTTP access. The fix uses...

GHSA-8HJW-25CG-G52H praisonaiagents has a `web_crawl` SSRF protection bypass via unchecked redirect targets

Summary praisonaiagents.tools.webcrawltools.webcrawl validates the initial URL and blocks direct loopback/private destinations by default, but the default httpx fallback still uses httpx.Clientfollowredirects=True and does not revalidate redirect targets. An attacker-controlled public URL can pas...

CVE-2026-57216

A flaw was found in RabbitMQ, a messaging and streaming broker. The AMQP 0-9-1, AMQP 1.0, and Stream Protocol authentication mechanisms incorrectly perform a loopback check. This allows a user, typically restricted to loopback connections such as a guest user, to connect remotely. This occurs whe...

CVE-2026-71366

A server-side request forgery SSRF vulnerability was found in multiple AWX notification backends. The webhook, Mattermost, Rocket.Chat, and Grafana notification backends use notification template URLs as direct HTTP request targets without validating the target address against private, loopback, ...

CVE-2026-72860: Server-Side Request Forgery (SSRF)

The POST /api/provider-nodes/validate route in 9router takes a caller-supplied baseUrl and issues server-side HTTP requests to it, guarding the destination with assertPublicUrl from src/shared/utils/ssrfGuard.js. That guard compares hostname strings only: it resolves no DNS, does not revalidate...
