CVE-2026-57175
Description
A flaw was found in social-auth-core. The Security Assertion Markup Language (SAML) backend accepts authentication responses without verifying that they correspond to a previously issued authentication request. A remote authenticated attacker with a valid account on a trusted Identity Provider (IdP) can exploit this flaw in applications using SAML account association to link their identity to a logged-in victim's account. This allows the attacker to authenticate through SAML and gain unauthorized access to the victim's account.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
