Descripción técnica

Langflow is a tool for building and deploying AI-powered agents and workflows. From 1.5.0 until 1.10.3, an IP spoofing vulnerability in the Model Context Protocol (MCP) configuration installation endpoint (POST /api/v1/mcp/project/{project_id}/install) allowed authenticated remote attackers to bypass the "local-only" access restriction. By sending a spoofed X-Forwarded-For: 127.0.0.1 header, an attacker could make the server treat the request as originating from localhost, letting them write/overwrite an MCP client configuration file on the server's filesystem. This vulnerability is fixed in 1.10.3.

———Insufficient verification of data authenticity (CWE-345) in the external OIDC login callback in Cloud Foundry UAA v4.5.0 to v79.6.0 (inclusive) allows an authenticated UAA user to bypass the OAuth authorization-code exchange and establish an authenticated external-OIDC browser session, via submitting a UAA access token or a cross-client ID token as the callback’s id_token parameter. The issue only manifests when a UAA zone is configured with an OIDC identity provider whose issuer exactly matches that zone’s own /oauth/token endpoint (a “self-UAA” OIDC configuration). In this configuration, the callback takes a supplied id_token directly instead of requiring the authorization code exchange, and does not verify that the token was actually issued as an ID token for the specific self-OIDC relying-party client. An attacker holding any valid UAA JWT for themselves — including a plain access token with only uaa.user scope, or a valid ID token issued to an unrelated client such as cf — can present it as the callback’s id_token and be authenticated into a mapped local (“shadow”) account. Because the resulting session is not verified against the originating token’s true audience or user_id, its effective privilege depends entirely on the shadow account’s group memberships, which can include administrative scopes such as clients.write. Exploitation requires a valid UAA user JWT, a valid browser login state for the target zone, and the presence of a self-referential OIDC provider configuration — this is not a pre-authentication vulnerability, and does not by itself grant privileges beyond those already held by the mapped shadow account.6h CVE-2026-415587.5 ALT

——0Plane is an open-source project management tool. Prior to 1.4.0, Plane trusts email addresses returned by Gitea OAuth and by self-managed GitLab OAuth deployments where email confirmation is disabled, without verifying that the provider authenticated ownership of the address. An attacker can set an OAuth identity's unverified provider email to a victim's address, which Plane matches directly to the victim's existing local account. The attacker can then log in to the victim's Plane account without knowing the victim's password. GitHub, GitLab.com, and Google are not affected because those providers return verified email addresses. This issue is fixed in 1.4.0.23h
