Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Organizations should immediately audit and restrict developer-level privileges to trusted personnel only, minimizing the risk of exploitation. Implement strict access controls and monitoring on the Authorino service to detect unusual resource consumption patterns indicative of exploitation attempts. Employ resource quotas and limits at the container or pod level within the cluster orchestration platform to prevent any single service or user from exhausting system resources. Until an official patch is released, consider deploying fallback authentication mechanisms or redundant policy evaluation services to maintain availability. Regularly update and monitor Authorino releases for patches addressing this vulnerability. Additionally, conduct security awareness training for developers to recognize and avoid actions that could trigger resource exhaustion. Finally, implement network segmentation and rate limiting to reduce the attack surface and mitigate potential abuse from compromised developer accounts.

Description

A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster

Impact

The primary impact of this vulnerability is the denial of service of the Authorino service, which is critical for enforcing authentication policies in cluster environments. Organizations using Authorino to manage access controls risk having their authentication policy evaluations halted, potentially allowing unauthorized access if fallback mechanisms exist or causing service disruptions if authentication failures block legitimate access. This can affect the availability of applications and services relying on these policies, leading to operational downtime and potential business impact. Since the vulnerability requires developer-level privileges, insider threats or compromised developer accounts pose a significant risk. The lack of impact on confidentiality and integrity reduces the risk of data breaches but does not mitigate the operational consequences of service unavailability. The absence of known exploits in the wild currently limits immediate risk, but the medium severity and ease of exploitation warrant proactive mitigation.
