Descripción técnica

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.

———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 8.0.2.3h CVE-2026-1280763.1 BAJ

———Nuxt is an open-source web development framework for Vue.js. From 3.21.6 to before 4.0.0 and from 4.4.6 until 4.6.4, the /__nuxt_island path hash uses ohash serialization that does not escape quotes in string values or delimiters in object keys, allowing different island-prop tuples to produce the same path. For prerendering, substituted content is written into the generated page only if the crawler reaches a colliding URL before rendering the page with the legitimate props. Separately, a CDN or reverse proxy that keys island responses by path alone can be primed with the colliding response. If the substituted prop reaches v-html, innerHTML, or another unsafe HTML sink, the response can execute script in the application origin; otherwise the impact is content substitution. Applications that do not use server components or NuxtIsland, islands without attacker-influenced string props, and responses not cached by path alone are unaffected. This issue is fixed in version 4.6.4.7h CVE-2026-1291007.2 ALT

———Cudy TR3000 before 2.5.42 contains a remote code execution vulnerability that allows authenticated administrators to execute commands as root by uploading crafted OpenVPN private or tls-auth keys. Attackers can close the inline key block with </key>, inject directives such as tls-verify that bypass the .ovpn denylist, and have OpenVPN execute the hook as root.9h CVE-2026-1283484.2 MED

——0ExcelJS through 4.4.0 contains a formula injection vulnerability in the totals row formula getter in lib/doc/table.js that fails to escape [, ], # and ' characters in structured reference column names. Attackers can supply column names containing ] via untrusted input like imported CSV headers to inject formulas such as HYPERLINK that exfiltrate cell values when users open and click the generated workbook.7h CVE-2026-1263674.8 MED

——0@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Before 1.13.2, and from 1.14.0 through 1.14.1, the @grpc/grpc-js-xds SafeRegexValueMatcher and PathSafeRegexValueMatcher add start and end anchors without grouping a supplied top-level alternation. An expression intended to match one of several complete values can therefore match a prefix, substring, or suffix. The affected matchers are used for route selection, xDS credential identity matching, and RBAC URL path, principal name, server name, and header rules. An ALLOW policy using an alternation can consequently accept a method, certificate identity, or header value outside the intended set, while a DENY policy becomes broader rather than permissive. This issue is fixed in versions 1.13.2 and 1.14.2.1d CVE-2026-1262036.1 MED

——0Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. From 2.21.0 until 2.25.3, Loofah's HTML5 APIs Loofah.html5_fragment, Loofah.html5_document, and the scrub_html5_* methods can emit sanitized output that a browser reparses as different markup when used with Nokogiri before 1.19.5, because those Nokogiri versions do not escape angle brackets in attribute values. MathML can place markup inside an allowed attribute so the reparsed output becomes live HTML. The :strip scrubber is affected in every browser, while :prune and :escape are affected in WebKit browsers. Loofah's HTML4 APIs, Loofah::Helpers.sanitize, :whitewash, rails-html-sanitizer's default configuration, and JRuby are not affected. This issue is fixed in version 2.25.3.1d
