Descripción técnica

Weaver e-Bridge contains an unauthenticated arbitrary file read vulnerability that allows remote attackers to access arbitrary files on the host system by supplying a file: URL to the downloadUrl parameter of the saveYZJFile endpoint. Attackers can exploit this flaw to read sensitive files such as /etc/passwd or configuration and credential files, and the same endpoint's support for http(s) URLs also enables server-side request forgery against internal network resources. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.

——0UTMStack before 11.2.16 contains a server-side request forgery vulnerability that allows authenticated attackers to make the server request arbitrary internal resources by supplying an unvalidated url parameter to the PdfService.downloadPdf() method exposed via GET /api/generate-pdf-report. Attackers can leverage this to force the web-pdf microservice to fetch internal backend endpoints, the OpenSearch cluster, or the cloud instance-metadata service, exposing sensitive internal data rendered into the returned PDF.12h CVE-2026-820405.0 MED

——0UTMStack before 11.2.16 contains a server-side request forgery vulnerability in IdentityProviderService.validateMetadataUrl() that allows authenticated attackers to make the server send requests to arbitrary internal or cloud metadata hosts by supplying a malicious metadata URL to the identity-providers endpoint. Attackers can exploit the POST/PUT /api/identity-providers endpoint with no validation of target host, IP, or scheme to perform internal network port scanning and access cloud instance-metadata services.13h CVE-2026-1039587.6 ALT

——0Server-side request forgery in the tool server and remote agent connection handling in Loom for AWS before 1.7.0 might allow an authenticated remote user to obtain the credentials of the application's own container role and to read responses from arbitrary internal network locations, via a crafted connection address supplied when registering, updating or testing a tool server or remote agent. To remediate this issue, users should upgrade to version 1.7.0 or later.13h CVE-2026-1039576.2 MED

——0Server-side request forgery in the OAuth2 discovery handling in Loom for AWS before 1.7.0 might allow an authenticated remote user to obtain the access token of another user of the deployment and to cause the application to issue requests to arbitrary internal network locations, via a crafted discovery document address supplied when registering a tool server or remote agent configured for delegated authentication. To remediate this issue, users should upgrade to version 1.7.0 or later.13h CVE-2026-94483—

——0Next.js is a React framework for building full-stack web applications. From 16.0.0 until 16.3.8, Image Optimization can follow attacker-controlled DNS resolution for a remote URL that matches images.remotePatterns, allowing the optimized image fetch to reach private IP addresses after the URL passes the allow-list check. Applications without images.remotePatterns are not affected. Administrators unable to upgrade should audit allow-listed hosts and avoid entries whose DNS records are not trusted. This issue is fixed in version 16.3.8.15h CVE-2026-1027976.4 MED
