Frappe Builder before 1.36.1 contains a server-side request forgery vulnerability in builder/api.py where the assert_not_private_url() guard validates only the initial hostname before callers invoke requests.get(url) with default redirect-following and no IP pinning, allowing an attacker-supplied public URL to HTTP-redirect to internal or link-local addresses the guard never validated. An authenticated attacker can call the convert_to_webp endpoint, which lacks a permission decorator, with a URL that redirects to internal targets such as cloud metadata services to perform SSRF, internal port scanning, or trigger a request-hang denial of service due to the missing timeout.

CVE-2026-938482.7 BAJ—
———Mattermost versions 11.7.x <= 11.7.10 fail to apply outbound internal-connection filtering to the OpenID discovery endpoint request which allows a System Administrator to determine whether internal addresses and ports are reachable from the server via an unauthenticated login request that triggers the discovery fetch.. Mattermost Advisory ID: MMSA-2026-007744hCVE-2026-1162805.5 MED—
———A vulnerability was determined in Kameleo up to 5.0.1.26. Affected is the function InternalController.TestProxy of the file client-engine-application/f.cs of the component Proxy Validation. Executing a manipulation of the argument host/port can lead to server-side request forgery. The attack may be launched remotely. Upgrading to version 5.2.0 is able to address this issue. It is suggested to upgrade the affected component. The route has been removed and replaced with /general/test-proxy in 5.2.0.7hCVE-2026-115700——
———Interpretation Conflict vulnerability in hackney_url in benoitc hackney allows Server Side Request Forgery via a percent-encoded bracketed IPv6 literal or an IP literal with a trailing dot. A host such as %5B%3A%3Affff%3A127%2E0%2E0%2E1%5D (decoding to [::ffff:127.0.0.1]) or 127.0.0.1. is not an IP address to a caller's allowlist built on uri_string:parse/1 and inet:parse_address/1, while hackney connects to the address it denotes. The same applies to a Location target when redirects are followed.
The IP-literal gate that hackney_url:normalize/2 applies to a percent-decoded host, added to close the percent-encoded IP bypass of CVE-2026-47076, passes the decoded value to inet_parse:address/1 as is. The connect path in hackney_happy:parse_address/1 drops a surrounding bracket pair, and the resolver ignores a trailing dot, so both forms pass the gate and still reach the literal address. Domain names with a trailing dot and unencoded IPv6 literals are not affected.
This issue affects hackney: from 4.0.1 before 4.9.0.4hCVE-2026-1157177.7 ALT—
———Frappe Builder versions before 1.36.1 contain a server-side request forgery vulnerability in the convert_to_webp API endpoint, which lacks the has_page_write access control applied to similar asset-ingest handlers and performs an unprotected requests.get call that follows redirects without re-validating resolved IP addresses. A low-privilege authenticated user can supply an image_url pointing to an internal address or use DNS rebinding and open redirects to make the server fetch internal network resources or cloud metadata endpoints, with successful image responses saved to a world-readable /files/ URL enabling data exfiltration or blind probing of internal hosts.4hCVE-2026-1162567.3 ALT—
——0A vulnerability was found in geesondog RhaPHP up to 7ae639ccf8dcb627faace096d030bd4cb4cfb905. Affected by this vulnerability is the function image of the file application/mp/controller/Show.php of the component Mp Module Media Proxy. The manipulation of the argument url results in server-side request forgery. The attack may be launched remotely. The exploit has been made public and could be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way.4hCVE-2026-1162244.3 MED—
——0A vulnerability has been found in fr0tt benotes up to 2.8.1. This affects the function getUrlInfo of the file app/Http/Controllers/PostController.php of the component Bookmark Metadata Endpoint. The manipulation of the argument url leads to server-side request forgery. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.4h
