CVE-2025-48098

Step 1: Payload Injection: An attacker crafts a malicious JavaScript payload (e.g., <script>alert('XSS')</script>) and injects it into a vulnerable input field within the Survey Maker plugin, such as a survey question, answer option, or user comment field.

Step 2: Data Storage: The malicious payload is stored within the plugin's database, associated with the survey or user data.

Step 3: Payload Retrieval: When a legitimate user views the survey or interacts with the data containing the malicious payload, the plugin retrieves the stored data from the database.

Step 4: Unsanitized Rendering: The plugin fails to properly sanitize or encode the attacker's injected JavaScript payload before rendering it in the HTML output.

Step 5: Code Execution: The user's web browser interprets the injected JavaScript as part of the webpage's code and executes it within the context of the vulnerable website, leading to the XSS attack.

The vulnerability stems from an improper neutralization of input during web page generation. Specifically, the Survey Maker plugin fails to adequately sanitize user-supplied data before displaying it within the survey interface. This allows attackers to inject malicious JavaScript payloads into fields such as survey questions, answers, or user comments. When other users view the survey or interact with the compromised data, the injected script executes within their browsers, enabling a wide range of attacks. The root cause is likely a missing or insufficient input validation and output encoding mechanism within the plugin's code, allowing unsanitized user input to be directly rendered in the HTML output.
