CVE-2025-25209

Root

Cause

The AuthPolicy metadata object in Red Hat Connectivity Link contains a sharedSecretRef that references secrets but assumes they reside in the kuadrant-system namespace instead of copying them to the target namespace [1][2]. This design error means the referenced secrets are not isolated per-namespace.

Exploitation

An attacker with a developer persona — who would normally lack permission to read secrets in the kuadrant-system namespace — can exploit this by knowing the secret's name (either through direct knowledge or brute-force) and then leaking it over an HTTP connection [2]. The attack is limited to secrets that are only one line long and requires no special authentication beyond the developer-level access [1].

Impact

Successful exploitation allows the attacker to exfiltrate secrets they are unauthorized to view from the kuadrant-system namespace [2]. By default, this namespace does not contain highly sensitive secrets, but the flaw still undermines the confidentiality guarantees of the platform [2].

Mitigation

Red Hat has acknowledged the issue and is tracking it via Bugzilla [2]. Users should monitor for patched releases and consider restricting developer access to the kuadrant-system namespace as a workaround until an official update is available [1][2].
