CVE-2024-39315

20
FAUCET Score

CVE-2024-39315 affects Pomerium versions prior to 0.26.1, where the user info page at /.pomerium unintentionally exposed serialized OAuth2 access and ID tokens. This vulnerability has a CVSS score of 6.5 (MEDIUM), indicating that an attacker could potentially gain high confidentiality impact through user interaction, particularly if combined with a cross-site scripting vulnerability in an upstream application. While these tokens alone don't hijack a Pomerium session, they could lead to user impersonation in improperly configured upstream applications. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
