Descripción técnica

SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to version 1.17.0, in src/endpoints/search.js, the hostname is checked against /^\d+\.\d+\.\d+\.\d+$/. This only matches literal dotted-quad IPv4 (e.g. 127.0.0.1, 10.0.0.1). It does not catch: localhost (hostname, not dotted-quad), [::1] (IPv6 loopback), and DNS names resolving to internal addresses (e.g. localtest.me -> 127.0.0.1). A separate port check (urlObj.port !== '') limits exploitation to services on default ports (80/443), making this lower severity than a fully unrestricted SSRF. This issue has been patched in version 1.17.0.

———A vulnerability was identified in graphlit graphlit-mcp-server 1.0.1. This affects the function fetch of the file src/tools.ts of the component ssrf-test Endpoint. Such manipulation of the argument url leads to server-side request forgery. The attack may be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.5h CVE-2026-199566.3 MED

———A vulnerability has been found in gomarble-ai facebook-ads-mcp-server 0.1.0. The impacted element is the function fetch_pagination_url of the file server.py. Such manipulation leads to server-side request forgery. The attack can be launched remotely. The name of the patch is 4e53875aa22e8991c2fa4a7660d86e1caba66659. Applying a patch is advised to resolve this issue.6h CVE-2026-730585.8 MED

———stoatchat versions before 0.15.0 fail to block the IPv6 unspecified address (::) in the SSRF blocklist, allowing unauthenticated attackers to bypass protections via the /proxy and /embed endpoints. Attackers can craft requests using IPv6 literal syntax to access services on the loopback interface and retrieve sensitive internal content.13h CVE-2026-171238.8 ALT

——0The Royal Elementor Addons plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.7.1064 via the Form Builder widget's 'webhook_url' setting. The widget's render() method persists the attacker-controlled URL into the wpr_webhook_url_{widget_id} option on every render (including a Contributor previewing their own draft), and the wpr_form_builder_webhook AJAX handler — registered for both authenticated and unauthenticated callers — reads that option and dispatches the outbound request via the non-safe wp_remote_post(), with no host allowlist, no scheme restriction, and no private/loopback IP filter (the plugin's existing wpr_is_blocked_remote_host / wpr_is_private_or_local_ip helpers are not called on this path). This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.22h CVE-2026-199276.3 MED

——0A vulnerability was found in OpenBoxes up to 0.9.7. The impacted element is the function Upload of the file grails-app/controllers/org/pih/warehouse/product/ProductController.groovy of the component Product Upload Endpoint. Performing a manipulation of the argument params.url results in server-side request forgery. The attack is possible to be carried out remotely. The exploit has been made public and could be used. Upgrading to version 0.9.8-hotfix1 and 0.9.8 is sufficient to resolve this issue. The patch is named a599007325efe780a21b3537ecce3ca25635c926. It is suggested to upgrade the affected component.1d CVE-2026-742474.2 MED

——1A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API. This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.2d
