CVE-2026-82241
Description détaillée
Budibase backend-core (@budibase/backend-core, as used by @budibase/server) omits the shared address space range 100.64.0.0/10 from its default SSRF blacklist (DEFAULT_BLACKLIST) used by REST datasource query previews. When the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Per the advisory, no released fix was identified at the time of publication; remediation is to add 100.64.0.0/10 to DEFAULT_BLACKLIST.

Dernières Vulnérabilités
CVE-2026-82261
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.
CVE-2026-82260
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.
CVE-2026-82259
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.
