Technical description

go-shiori's DownloadBookmark() (internal/core/download.go) fetches a caller-supplied bookmark URL using a plain http.Client with no custom DialContext or destination-IP validation (no IsLoopback(), IsPrivate(), IsUnspecified(), or IsLinkLocalUnicast() checks). An authenticated user creating or updating a bookmark via POST /api/bookmark, PUT /api/v1/bookmarks/cache, or POST /api/bookmarks/ext can supply a loopback (127.0.0.1) or 0.0.0.0 (which Linux redirects to loopback) URL, causing the server to make outbound requests to internal-only services, cloud metadata endpoints, or other network-restricted resources.

———A server-side request forgery vulnerability in Progress MarkLogic Server before 11.3.6 and 12.0.3 allows an authenticated user with low-privileged roles to bypass protections for cloud instance metadata endpoints. Successful exploitation can disclose cloud credentials and compromise cloud resources accessible to the host instance.8h CVE-2026-706055.9 MED

———Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, when following HTTP redirects, net.fetch() and net.request() did not restrict which schemes a redirect could target. A remote server could redirect a request to a local resource, and if the app returns or forwards the response body, local file contents could be disclosed. Apps are only affected if they make net requests to attacker-influenced URLs with redirects followed and expose the response body. This issue is fixed in versions 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3.8h CVE-2026-705954.0 MED

———Ghost is a Node.js content management system. From 6.26.0 until 6.54.1, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network. A successful attack would not result in any response data being returned. This vulnerability is fixed in 6.54.1.8h CVE-2026-712718.5 HIG

———Memos' webhook URL validation, isReservedIP() (internal/webhook/validate.go), checks a candidate IP against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified() — unlike the correctly implemented sibling function isInternalIP() in internal/httpgetter/html_meta.go, which does. Because Linux redirects connections to 0.0.0.0 to loopback (127.0.0.1), an attacker registering a webhook URL of http://0.0.0.0:PORT/ bypasses the reserved-IP check and causes the Memos server to make outbound HTTP requests to its own loopback interface, exposing internal-only services.8h CVE-2026-712708.6 HIG

———Stirling-PDF's POST /api/v1/convert/url/pdf endpoint (ConvertWebsiteToPDF.java) was not updated with the CustomHtmlSanitizer/SsrfProtectionService SSRF protections that were added to three sibling conversion endpoints (html/pdf, file/pdf, markdown/pdf). The endpoint validates only that the initial requested URL resolves to a public IP, then fetches the page's HTML server-side and hands it, unsanitized, to a WeasyPrint subprocess. Embedded resource references in the fetched HTML (e.g. `<img src="http://169.254.169.254/...">`) are fetched by WeasyPrint with no per-resource SSRF filtering, allowing an attacker-controlled page to cause the server to retrieve cloud metadata endpoints or internal network resources and leak their contents back into the generated PDF.8h
