Descripción técnica

SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. From version 4.7.0 until versions 7.2.10 and 8.0.2, @sveltejs/adapter-cloudflare allowed an attacker-influenced link crawled during prerendering to place whitespace, control characters, wildcards, or placeholders into a prerendered redirect path. The adapter wrote those paths into the Cloudflare _redirects output without output-context validation, allowing a path to create unintended routing rules that could redirect or expose requests beyond the intended prerendered route. This issue is fixed in 7.2.10 and 8.0.2.

———IBM Cyber Fraud 1.0.0 through 1.1.0 is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.3h CVE-2026-1101994.8 MED

———SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to @sveltejs/adapter-vercel 6.3.5 and 7.0.2 and @sveltejs/adapter-static 3.0.11 and 4.0.1, an attacker-influenced link crawled during prerendering could be emitted into the generated Vercel routing configuration without escaping regular-expression metacharacters. The configuration could consequently interpret the path as regular-expression syntax, match unintended application paths, and expose content or behavior outside the intended path. This issue is fixed in @sveltejs/adapter-vercel 6.3.5 and 7.0.2 and @sveltejs/adapter-static 3.0.11 and 4.0.1.3h CVE-2026-1281165.3 MED

———SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to versions 2.70.4 and 3.1.1, apps configured with router.resolution: 'server' could treat a pathname beginning with // as a protocol-relative module specifier during client-side navigation. A socially engineered link could therefore make server-side route resolution import and execute JavaScript from another origin in the user's browser. This issue is fixed in 2.70.4 and 3.1.1.3h CVE-2026-67444—

———Hubleys is a dashboard for self-hosted services. Prior to version 0.5.2, any authenticated (non-admin) Hubleys user can upload a file with an arbitrary extension as their dashboard "background image," and the server will later serve that file back with a Content-Type derived straight from the attacker's chosen extension - so uploading an .html file gets it served as text/html. Because the endpoint that serves it returns a manually-constructed response rather than going through SvelteKit's normal page-rendering pipeline, the app's configured Content-Security-Policy never gets attached to it either, so a script embedded in the upload runs unrestricted. This issue has been patched in version 0.5.2.6h CVE-2026-1291725.4 MED

———EdgeEver 1.9.0 before 2.13.0 contains a stored cross-site scripting vulnerability in the backup restore endpoint PUT /api/v1/restores/json/resources/:id, which accepts a resource kind of image paired with a text/html MIME type without checking consistency. Authenticated members can share the note and send the public blob link to a victim, whose browser executes the script to mint a non-expiring API token granting read and write access to the victim's notes.7h
