Openshift/console: openshift/console: unauthenticated reverse proxy to in-cluster catalogd service with session token forwarding
CVSS Score

0.0%
EPSS Percentile
0th
A flaw was found in openshift/console. An unauthenticated remote attacker can exploit a misconfiguration in the CatalogdHandler, which lacks proper authentication, and the forwarding of the `openshift-session-token` cookie. This allows the attacker to send requests to the in-cluster catalogd service, leading to the disclosure of the internal operator-catalog index and providing a relay into the openshift-catalogd namespace.
