Technical description

The PowerPress Podcasting plugin by Blubrry plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'width' parameter in all versions up to, and including, 11.18.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when the site's configured video player is set to html5video, or when the media URL uses a .webm or .ogv extension, as these conditions are required to route the shortcode attributes through the vulnerable powerpressplayer_build_html5video() builder. Successful exploitation additionally requires an action by an editor — the attacker cannot trigger the vulnerability on their own.

———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 8.0.2.4h 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 3.1.1.4h 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 0.5.2.7h 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.8h
