SCA: security update for starlette (GHSA-82w8-qh3p-5jfq)

high Tenable Cloud Security Plugin ID 443221

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Starlette is a lightweight ASGI framework/toolkit. From 0.4.1 until 1.3.1, request.form() accepts
 max_fields and max_part_size to bound resource consumption while parsing form data. These limits are
 enforced for multipart/form-data, but silently ignored for application/x-www-form-urlencoded. An
 unauthenticated attacker can therefore send a urlencoded body with an arbitrarily large number of fields
 or an arbitrarily large field, even when the application configured limits it believed would apply. This
 vulnerability is fixed in 1.3.1. (CVE-2026-54283)

Solution

Update the starlette library and its related packages to version 1.3.1 or later.
