Mitigation availableOpen OnDemand provides remote web access to supercomputers. In versions 4.0.8 and prior, the Apache proxy allows sensitive headers to be passed to origin servers. This means malicious users can create an origin server on a compute node that record these headers when unsuspecting users connect to it. Maintainers anticipate a patch in a 4.1 release. Workarounds exist for 4.0.x versions. Using `custom_location_directives` in `ood_portal.yml` in version 4.0.x (not available for versions below 4.0) centers can unset and or edit these headers. Note that `OIDCPassClaimsAs both` is the default and centers can set `OIDCPassClaimsAs ` to `none` or `environment` to stop passing these headers to the client. Centers that have an OIDC provider with the `OIDCPassClaimsAs` with `none` or `environment` settings can adjust the settings using guidance provided in GHSA-2cwp-8g29-9q32 to unset the mod_auth_openidc_session cookies.

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-522: Insufficiently Protected Credentials. The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
