SCA: security update for social-auth-core (GHSA-h2r5-x5m7-3935)

medium Tenable Cloud Security Plugin ID 477766

Description

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

 - Python Social Auth is a social authentication and registration mechanism. Prior to 6.2.0,
 OpenIdConnectAuth in social_core/backends/open_id_connect.py uses get_and_store_nonce to place the OpenID
 Connect nonce in a shared OpenIdConnectAssociation table, and get_nonce and validate_claims verify only
 that the nonce exists and has not expired rather than binding it to the browser session and OAuth state
 that initiated the login. An attacker who obtains a victim's unused authorization code can start a
 separate login to obtain valid state for the attacker's browser, submit the victim's code with that state,
 and pass nonce validation because the victim nonce is globally available. With DEFAULT_USE_PKCE disabled
 in the default OpenIdConnectAuth configuration, the attacker can be logged in as the victim. This issue is
 fixed in version 6.2.0. (CVE-2026-115910)

Solution

Update the social-auth-core library and its related packages to version 6.2.0 or later.
