CVE-2026-59164: NORA is a self-hosted artifact registry and pull-through cache. Prior to 0.9.5, `nora-registry` authenticates the token-management UI but fails to require administrator authorization. `auth_middleware()` protects `/ui/tokens` and `/api/ui/tokens`, but state-changing requests are checked only with `role.can_write()`, not `role.can_admin()`. `tokens_page()` and `tokens_list()` call `store.list_all_tokens()`, exposing IDs and metadata across all users, while `tokens_revoke()` calls `store.revoke_token` using the supplied token ID without an ownership or admin check. A read bearer token can enumerate other users' token existence, owner, role, description, expiry and last-use metadata. A write bearer token or write-capable OIDC identity can additionally revoke arbitrary admin and service tokens, disrupting the registry and forcing credential recovery. Read-only identities cannot POST a revocation. This issue is fixed in version 0.9.5.
The exploitability of CVE-2026-59164 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-59164 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-59164, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-59164, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
