CVE-2024-10851 is a reflected cross-site scripting vulnerability in the Razorpay Payment Button Plugin for WordPress. The issue is due to improper neutralization of input during web page generation, specifically the lack of appropriate escaping when using add_query_arg and remove_query_arg functions on URLs. This allows unauthenticated attackers to inject arbitrary web scripts that execute when a user interacts with a maliciously crafted link. The vulnerability affects all versions up to and including 2.4.6. The CVSS 3.1 base score is 6.1, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, user interaction needed, and partial impact on confidentiality and integrity.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected site, potentially allowing attackers to steal user information or perform actions on behalf of the user. The impact is limited to confidentiality and integrity with no availability impact. Since exploitation requires user interaction, the risk is moderated but still significant for users who may be tricked into clicking malicious links.
