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...

CVE-2026-79671

Ech0 versions through 4.2.1 contain a server-side request forgery (SSRF) vulnerability in the validateWebhookURL function (webhook_setting_service.go). The validation only rejects literal IP addresses via net.ParseIP() but fails to reject hostnames that DNS-resolve to private or internal addresse...

CVE-2026-72860

9router 's POST /api/provider-nodes/validate route is vulnerable to Server-Side Request Forgery (SSRF) due to a flaw in its assertPublicUrl guard (src/shared/utils/ssrfGuard.js). The IPv4-mapped IPv6 denylist regex is unreachable because the WHATWG URL parser canonicalizes such literals to hextet...

CVE-2026-42260

Open-WebSearch CVE-2026-42260 describes a SSRF in fetchWebContent of the MCP tool where bracketed IPv6 literals and lack of DNS resolution allow bypassing the public URL checks. The vulnerability arises because isPublicHttpUrl / assertPublicHttpUrl in src/utils/urlSafety.ts treat bracketed IPv6 h...

GHSA-V228-72C7-FX8J open-websearch has SSRF in `fetchWebContent` MCP tool: bracketed IPv6 literals and non-resolving hostname check bypass `isPrivateOrLocalHostname`

Summary src/utils/urlSafety.ts exposes isPublicHttpUrl / assertPublicHttpUrl, used to gate the MCP fetchWebContent tool against private-network targets. The check has two defects that together allow non-blind SSRF with the response body returned to the caller: 1. Bracketed IPv6 literals are never...

GHSA-R2X7-427F-RQ69 Ech0 has SSRF via DNS Resolution Bypass in Webhook URL Validation

Summary The validateWebhookURL function in webhooksettingservice.go attempts to block webhooks targeting private/internal IP addresses, but only checks literal IP strings via net.ParseIP. Hostnames that DNS-resolve to private IPs e.g., 169.254.169.254.nip.io, 10.0.0.1.nip.io bypass all checks,...
