This flaw affects versions 2.95.0 to before 2.95.12 and 3.17.0 to before 3.131.0 when SSO provider configurations lack an explicit AUTH_<PROVIDER>_CHECK setting. An authenticated user could be compromised through a crafted URL via CSRF or phishing. The vulnerability carries a CVSS score of 6.5 (Medium), indicating a network-based attack with low complexity requiring user interaction, potentially leading to high confidentiality impact. There is no impact on integrity or availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE. Patches are available in versions 2.95.12 and 3.131.0, and a workaround involves setting AUTH_<PROVIDER>_CHECK.
