CVE-2026-82258
SvelteKit versions from 2.38.0 up to (but not including) 2.60.1 are affected by a race condition in the query.batch feature. Under specific timing conditions, concurrent requests from different users can merge under a single request context, allowing an attacker to access sensitive data from othe...
CVE-2026-82259 SvelteKit 2.49.0 before 2.53.3 Denial of Service via form
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...
EUVD-2026-67583
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...
CVE-2026-82257 SvelteKit before 2.69.1 Prototype Pollution via File Input
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...
CVE-2026-82257 SvelteKit before 2.69.1 Prototype Pollution via File Input

CVE-2026-82257
SvelteKit versions before 2.69.1 are affected by a prototype pollution vulnerability in remote form functions that accept file input fields with user-controlled path names. An attacker can manipulate the deletion path to remove methods on the object prototype, potentially disabling application fu...
EUVD-2026-67582
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...
CVE-2026-82256 SvelteKit before 2.69.1 Denial of Service via Remote Form
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...
CVE-2026-82256
SvelteKit versions prior to 2.69.1 contain a denial-of-service vulnerability in its remote form function handling. The root cause is a failure to properly validate payload sizes, allowing an unauthenticated network attacker to crash the Node process by sending abnormally large payloads. Repeated ...

CVE-2026-66062
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...
GHSA-29G2-3RMR-QM68 SvelteKit: ReDoS (O(n^2)) in content negotiation — unauthenticated DoS via the Accept header
Impact SvelteKit is vulnerable to remote CPU-exhaustion DoS attacks via specifically-crafted Accept headers. The impact is mitigated by default header length limits on most platforms, but in the case of raised or absent limits a denial of service is possible. Patches The vulnerability is patched ...

CVE-2026-66062
SvelteKit before 2.70.2 uses a content-negotiation header parser that employs a regular expression vulnerable to quadratic backtracking. A crafted Accept header can cause excessive CPU use, leading to degraded performance or denial of service. The issue is fixed in 2.70.2. No exploitation details...

GHSA-866W-XMHQ-WJ7X SvelteKit: Prototype pollution in file input deletion path in remote-function forms
If you use remote form functions, have an input field of type file, and accept arbitrary user-controlled path names for the field, then you are vulnerable to a prototype pollution attack where the attacker can remove e.g. methods on the prototype...
