Security Bulletin: Langflow is vulnerable to Server-Side Request Forgery due to missing or bypassable URL validation in multiple components

Summary Langflow contains multiple Server-Side Request Forgery vulnerabilities across several components where authenticated users can supply attacker-controlled URLs or database connection strings that reach internal network hosts without adequate validation. The LMStudio model and embeddings...

CVE-2026-101910

A flaw was found in ip-address. The address classification mechanism fails to identify the local-use Network Address Translation NAT64 range as private. A remote attacker can exploit this by submitting an internal address formatted within this IPv6 prefix to an application that relies on the...

CVE-2026-101907

A flaw was found in Axios. When configured to use the fetch adapter, the application does not enforce settings configured to disable HTTP redirects. A remote attacker controlling a redirecting server can exploit this behavior to force the application to follow redirects to internal endpoints,...

Server-side Request Forgery (SSRF)

Overview org.webjars.npm:axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via unsafe merging of user-supplied fetchOptions into the resolved request options object in lib/adapters/fetch.js. An...

CVE-2026-55160

Stringer is a self-hosted, anti-social RSS reader. Prior to commit 75cb095, an unrestricted Server-Side Request Forgery SSRF vulnerability allows any authenticated user to force the Stringer server to send arbitrary HTTP/HTTPS requests to internal networks, localhost services, and cloud metadata...

CVE-2026-101898

A flaw was found in axios. When processing HTTP/2 requests, the client fails to enforce configured proxy settings and custom Domain Name System DNS resolution policies. A remote attacker who can influence destination URLs could exploit this vulnerability to bypass outbound network restrictions,...

CVE-2026-101913

The ip-address JavaScript library, used for parsing and manipulating IPv4 and IPv6 addresses, contains a vulnerability in the Address6.isLinkLocal method within src/ipv6.ts in versions prior to 10.5.1 . The method incorrectly recognizes only the fe80::/64 prefix instead of the full fe80::/10 IPv6...

CVE-2026-101913 ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.5.1, the Address6 isLinkLocal method in src/ipv6.ts recognizes only fe80::/64 instead of the complete fe80::/10 IPv6 link-local range. An attacker-controlled address elsewhere in fe80::/10 can...
