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: 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: 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).

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 2026-10-26.

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

To mitigate CVE-2024-39013, organizations should immediately assess their use of 2o3t-utility v0.1.2 and related versions. If possible, discontinue or isolate the vulnerable utility until a patch is released. Employ strict input validation and sanitization to prevent injection of malicious properties into objects. Implement runtime application self-protection (RASP) or JavaScript security tools that detect and block prototype pollution attempts. Monitor application logs and network traffic for unusual behavior indicative of exploitation attempts. Restrict network access to services using the vulnerable utility, limiting exposure to trusted internal networks. Stay informed about vendor updates or patches and apply them promptly once available. Additionally, conduct code reviews and security testing focused on prototype pollution vectors in custom code that interacts with 2o3t-utility. Employ defense-in-depth strategies such as sandboxing and privilege separation to minimize potential damage from exploitation.

Description

2o3t-utility v0.1.2 was discovered to contain a prototype pollution via the function extend. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.

Impact

The impact of CVE-2024-39013 is severe for organizations using the affected 2o3t-utility version. Successful exploitation can lead to arbitrary code execution, allowing attackers to take full control of affected systems, steal sensitive data, or disrupt services through Denial of Service attacks. The vulnerability compromises confidentiality, integrity, and availability simultaneously, posing a critical risk to business operations. Since no authentication or user interaction is required, attackers can exploit this remotely and at scale, increasing the likelihood of widespread attacks once exploit code becomes available. Organizations relying on this utility in production environments, especially those exposed to the internet, face significant risk of compromise, data breaches, and operational downtime. The absence of patches further exacerbates the threat, potentially delaying remediation and increasing exposure time. This vulnerability could also be leveraged as a pivot point for lateral movement within networks, amplifying its impact in complex enterprise environments.

CWE-1321Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') (opens in a new tab)
Variant weakness
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
Implementation
By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.
Architecture and Design
By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.
Implementation · Input Validation
When handling untrusted objects, validating using a schema can be used.
