| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2026-82259 | 8.7 high | 1.0% | svelte, sveltekit | SvelteKit versions from 2.49.0 through 2.53.2 (fixed in 2.53.3) contain a deserialization expansion issue in the experimental form remote function. When an application enables experimental.remoteFunctions and uses the form function to process the files array without validating files.length or individual file sizes, an attacker can submit relatively small inputs that expand into very large file arrays, leading to expensive processing and denial of service. | 8 Oct |
| CVE-2026-40073 | 8.2 high | 1.0% | svelte, kit | SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.57.1, under certain circumstances, requests could bypass the BODY_SIZE_LIMIT on SvelteKit applications running with adapter-node. This bypass does not affect body size limits at other layers of the application stack, so limits enforced in the WAF, gateway, or at the platform level are unaffected. This vulnerability is fixed in 2.57.1. | Sun 25 Oct |
| CVE-2026-66062 | 5.3 medium | 1.0% | no CPE yet | SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.70.2, the content negotiation header parser used by SvelteKit's request handling (for headers such as Accept) uses a regular expression vulnerable to quadratic backtracking, so a maliciously crafted header value can cause excessive CPU consumption and degrade or deny service. Version 2.70.2 fixes the issue. | Sat 24 Oct |
| CVE-2026-82261 | 8.7 high | 0.00% | svelte, sveltekit | SvelteKit (@sveltejs/kit) versions >=2.49.0 and <=2.52.1 with experimental remote functions and form enabled contain a CPU exhaustion vulnerability in form deserialization. An attacker can send malformed form data to cause the server to become unresponsive while processing the request, resulting in denial of service. Fixed in 2.52.2. | 8 Oct |
| CVE-2026-82260 | 8.7 high | 0.00% | svelte, sveltekit | SvelteKit (@sveltejs/kit) versions >=2.49.0 and <=2.52.1 with experimental remote functions (experimental.remoteFunctions) and form enabled contain a memory exhaustion vulnerability in remote form deserialization. Malformed form data can cause excessive memory allocation, crashing the server process and resulting in denial of service. Fixed in 2.52.2. | 8 Oct |
| CVE-2026-109290 | 8.4 high | 0.00% | no CPE yet | Open WebUI from 0.11.1 before 0.11.4 contains a stored cross-site scripting vulnerability in DocxPreview.svelte that allows authenticated users to execute script by uploading crafted DOCX attachments. Attackers can embed an OOXML altChunk HTML part or script-scheme hyperlink to steal a previewing administrator's session token from local storage and take over the instance. | Fri 23 Oct |
| CVE-2026-109288 | 7.2 high | 0.00% | no CPE yet | Open WebUI before 0.11.4 contains a stored cross-site scripting vulnerability in MarkdownInlineTokens.svelte, which renders markdown link URLs into anchor hrefs without validating their scheme. Authenticated users can embed javascript: links in shared chats that, when clicked by a victim, steal the victim's JWT from local storage, including admins' tokens. | Fri 23 Oct |
| CVE-2026-82256 | 6.9 medium | 0.00% | svelte, sveltekit | SvelteKit before 2.69.1 fails to properly validate remote form function payload sizes, allowing attackers to crash the Node process by sending large payloads. Repeated exploitation causes denial of service by repeatedly crashing the application process. | 8 Oct |
| CVE-2026-40074 | 6.3 medium | 0.00% | svelte, kit | SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.57.1, redirect, when called from inside the handle server hook with a location parameter containing characters that are invalid in a HTTP header, will cause an unhandled TypeError. This could result in DoS on some platforms, especially if the location passed to redirect contains unsanitized user input. This vulnerability is fixed in 2.57.1. | Mon 26 Oct |
| CVE-2026-82258 | 5.9 medium | 0.00% | svelte, sveltekit | SvelteKit versions from 2.38.0 before 2.60.1 contain a race condition in query.batch that allows concurrent requests from different users to merge under a single request context. Attackers can exploit specific timing conditions to access sensitive data from other users' concurrent requests. | 8 Oct |
| CVE-2026-82257 | 5.3 medium | 0.00% | svelte, sveltekit | SvelteKit versions before 2.69.1 contain a prototype pollution vulnerability in remote form functions with file input fields that accept arbitrary user-controlled path names. Attackers can manipulate the deletion path to remove methods on the prototype, potentially disabling application functionality. | 8 Oct |
