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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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

Monitor netbird management service updates closely and apply patches immediately once a fix addressing the static IV issue is released.
If patches are unavailable, consider disabling or restricting access to the audit events database to trusted personnel and networks only.
Implement network segmentation and strict firewall rules to limit exposure of netbird management services to external or untrusted networks.
Review and enhance logging and monitoring to detect unusual access patterns to audit event data.
Conduct a cryptographic audit of the netbird management service configuration to ensure no other weak cryptographic practices are in use.
Educate security teams about the risks of static IVs and the importance of proper cryptographic implementations.
Where feasible, encrypt audit event data at rest using strong, properly implemented encryption schemes with dynamic IVs or nonces.
Prepare incident response plans to address potential data exposure incidents involving email addresses or other sensitive information.
Evaluate alternative management solutions if timely patching or mitigation is not possible.

Description

CVE-2024-41260 is a high-severity vulnerability in netbird management service versions 0.23.2 to 0.29.1, caused by the use of a static initialization vector (IV) in its encryption function. This flaw allows attackers who gain access to the audit events database to decrypt sensitive information, specifically email addresses. The vulnerability does not require authentication or user interaction and can be exploited remotely. Although no known exploits are currently reported in the wild, the weakness in cryptographic implementation poses a significant confidentiality risk. The CVSS score of 7.5 reflects the high impact on confidentiality with low attack complexity.

Impact

For European organizations, the exposure of email addresses through this vulnerability can lead to privacy breaches, regulatory non-compliance (e.g., GDPR violations), and reputational damage. Attackers obtaining email addresses could perform phishing campaigns, social engineering, or identity theft. Since the vulnerability does not affect integrity or availability, operational disruption is unlikely, but the confidentiality breach alone is significant. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, face heightened risks. Additionally, the potential for lateral movement or escalation exists if attackers leverage exposed information to target other systems. The remote and unauthenticated nature of the exploit increases the threat surface, especially for organizations exposing netbird management services to untrusted networks. The lack of known exploits in the wild provides a window for proactive mitigation before active exploitation occurs.
