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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Immediately restrict access to password reset functionality to trusted roles only, ensuring that low-privilege users like 'viewer' cannot trigger password reset token generation for other accounts.
Implement strict server-side validation and authorization checks to confirm that password reset tokens are only issued to legitimate requesters for their own accounts.
Monitor logs for unusual password reset requests originating from viewer role users or other low-privilege accounts.
Employ multi-factor authentication (MFA) on all user accounts to reduce the impact of compromised credentials.
Isolate and segment systems running lunary-ai/lunary to limit lateral movement in case of compromise.
Engage with the vendor for timely patches or updates addressing this vulnerability and apply them as soon as available.
Conduct internal security audits and penetration testing focusing on access control and token management mechanisms.
Educate users about phishing and social engineering risks that could compound the vulnerability exploitation.
Consider implementing rate limiting and anomaly detection on password reset endpoints to detect and block abuse attempts.

Description

In lunary-ai/lunary version 1.2.2, an account hijacking vulnerability exists due to a password reset token leak. A user with a 'viewer' role can exploit this vulnerability to hijack another user's account by obtaining the password reset token. The vulnerability is triggered when the 'viewer' role user sends a specific request to the server, which responds with a password reset token in the 'recoveryToken' parameter. This token can then be used to reset the password of another user's account without authorization. The issue results from an excessive attack surface, allowing lower-privileged users to escalate their privileges and take over accounts.

Impact

For European organizations using lunary-ai/lunary, this vulnerability poses a significant risk of account hijacking, leading to unauthorized access to sensitive data and systems. Attackers exploiting this flaw can escalate privileges from a low-privilege viewer role to full account control, potentially compromising confidential information and disrupting business operations. The lack of user interaction and network-based exploitability increases the likelihood of automated or targeted attacks. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on lunary-ai/lunary for collaboration or data management could face data breaches, regulatory non-compliance, and reputational damage. The vulnerability could also facilitate lateral movement within networks, enabling attackers to compromise additional systems. Given the critical severity, the impact extends beyond individual accounts to organizational security posture and data integrity.
