HIGH7.1

Published 2026-07-09 · Updated 2026-07-10 · Source prodsec@nozominetworks.com

Description

An Open Redirect vulnerability was discovered in the SAML Single Sign-On functionality due to insufficient validation of a user-controlled redirection parameter. An unauthenticated attacker can craft a request to the SAML sign-in endpoint and poison the cached SAML redirection for other users who subsequently initiate SAML Single Sign-On, enabling phishing and credential-theft attacks, as well as disrupting SAML authentication for all affected users.

CVE-2026-72594
A stored cross-site scripting (XSS) vulnerability in lobehub/lobe-chat through v2.2.13 allows a low-privileged authenticated user to inject arbitrary JavaScript into the application by uploading a crafted SVG file as a user avatar. The avatar upload handler derives the stored file extension and S3 content type from the original filename rather than inspecting file content, enabling an attacker to store an SVG containing a script element that executes in the browser of any user who views the attacker's profile or avatar.

CVE-2026-72591
A server-side request forgery (SSRF) vulnerability in gabehf/Koito through v0.3.2 allows an authenticated user to make the server perform HTTP requests to arbitrary internal or external hosts by supplying a crafted image_url value in the PATCH /apis/web/v1/album/{id}/image endpoint. The application fetches the supplied URL server-side without validating the destination host or blocking access to private, loopback, link-local, or internal addresses.

CVE-2026-72586
A missing authentication vulnerability in frangoteam/FUXA through 1.3.3 allows an unauthenticated remote attacker to query all historical sensor data via the DAQ_QUERY Socket.IO event. When secureEnabled=true, all other sensitive Socket.IO events (DEVICE_BROWSE, HOST_INTERFACES, DEVICE_TAGS_REQUEST, etc.) call isSocketAdminAuthorized() to verify the connection token, but the DAQ_QUERY handler in server/runtime/index.js lacks this check entirely.

CVE-2026-72584
A time-of-check/time-of-use (TOCTOU) race condition in fastschema through v0.15.1 allows an unauthenticated remote attacker to bypass the OTP attempt limit on the account recovery flow, enabling brute-force attacks on 6-digit OTP codes. The verifyOTPSession function in pkg/auth/local.go reads and increments the attempt counter in separate non-atomic operations, allowing concurrent requests to observe the same attempt count below the threshold and proceed past the limit check before any update is committed.

CVE-2026-72582
A NULL pointer dereference vulnerability in fastschema through v0.15.1 allows an unauthenticated remote attacker to crash the server process with a single HTTP request. The sendOTPEmail function in pkg/auth/local.go dereferences a pointer obtained from an unchecked error path without validating it is non-nil, causing a fatal panic that terminates the entire server when a recovery request is sent to the /api/auth/local/recover endpoint.
