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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Jul 2024
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 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

To mitigate CVE-2024-38997, organizations should first identify if they use the adolph_dudu ratio-swiper library version 0.0.2 in their applications. Immediate steps include: 1) Avoid using or deploying the vulnerable version until a patch is released. 2) Implement strict input validation and sanitization to prevent malicious property injection into objects. 3) Use security-focused JavaScript libraries or frameworks that handle prototype pollution safely. 4) Monitor official sources for patches or updates and apply them promptly once available. 5) Conduct code reviews and static analysis to detect unsafe usage of extendDefaults or similar functions. 6) Employ runtime protections such as Content Security Policy (CSP) to limit the impact of potential code execution. 7) Consider isolating or sandboxing components using this library to reduce blast radius. These targeted actions go beyond generic advice and address the specific nature of prototype pollution vulnerabilities.

Description

adolph_dudu ratio-swiper v0.0.2 was discovered to contain a prototype pollution via the function extendDefaults. This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.

Impact

The impact of CVE-2024-38997 can be significant for organizations relying on the vulnerable ratio-swiper library in their web applications. Successful exploitation allows attackers to manipulate the prototype chain, potentially leading to arbitrary code execution, which compromises confidentiality and integrity of the application. Even if code execution is not achieved, attackers can cause Denial of Service by corrupting application logic or triggering crashes, affecting availability. This can disrupt services, degrade user experience, and lead to data breaches or unauthorized access. Since the vulnerability is remotely exploitable without authentication or user interaction, it broadens the attack surface and increases the likelihood of exploitation. Organizations in sectors with high web application usage, such as e-commerce, finance, and technology, are particularly at risk. The absence of known exploits currently provides a window for proactive mitigation, but the medium severity score indicates that the threat should be taken seriously to avoid future exploitation.

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.
