The vulnerability in Plotly plotly.js before version 2.25.2 involves a risk of __proto__ pollution in the expandObjectPaths or nestedProperty functions. This type of vulnerability can lead to prototype pollution, where an attacker can manipulate the prototype chain of JavaScript objects, potentially leading to arbitrary code execution or other severe security issues.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates that this vulnerability is critical and poses a significant risk to systems using the affected versions of Plotly plotly.js.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Web Applications: Web applications that use Plotly plotly.js for data visualization are at risk. An attacker could exploit this vulnerability by injecting malicious data into the plot API calls.
• Third-Party Integrations: Applications that integrate Plotly plotly.js through third-party libraries or services could also be vulnerable if they do not properly sanitize input data.

Exploitation Methods:

• Prototype Pollution: An attacker can manipulate the __proto__ property to inject malicious properties into the prototype chain, leading to unintended behavior or code execution.
• Data Injection: By injecting specially crafted data into the plot API calls, an attacker can exploit the vulnerability to achieve prototype pollution.

3. Affected Systems and Software Versions

Affected Software:

• Plotly plotly.js versions before 2.25.2

Affected Systems:

• Any system or application that uses the affected versions of Plotly plotly.js for data visualization.
• Web applications, data analytics platforms, and any other software that integrates Plotly plotly.js.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update to the Latest Version: Upgrade to Plotly plotly.js version 2.25.2 or later, which includes the fix for this vulnerability.
