SCA: security update for oauthlib (GHSA-hj66-6f7g-4r5v)

medium Tenable Cloud Security Plugin ID 448480

Description

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

- OAuthLib is an implementation of the OAuth request-signing logic for Python 3.6+. From 0.6.1 until 4.0.0,
OAuthLib's RevocationEndpoint in oauthlib/oauth2/rfc6749/endpoints/revocation.py reflects an unvalidated
callback request parameter into success and error response bodies when enable_jsonp=True. The callback can
come from the query string or request body and is used without restricting it to a legal JavaScript
function name. A browser application that loads the revocation response as trusted JSONP and permits
attacker influence over callback can therefore execute attacker-controlled JavaScript in the including
application's origin, with access to its DOM and script-accessible data. The feature is disabled by
default, so only deployments that explicitly enable JSONP are affected. This issue is fixed in version
4.0.0. (CVE-2026-49264)

Solution

Update the oauthlib library and its related packages to version 4.0.0 or later.
