CVE-2024-7791 is a stored Cross-Site Scripting vulnerability (CWE-79) in the Xpro Addons — 140+ Widgets for Elementor WordPress plugin. The flaw arises from improper neutralization of input in the 'arrow' parameter of the Post Grid widget, allowing authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who view the compromised pages. The vulnerability affects all plugin versions up to 1.4.4.3. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requires privileges, no user interaction, scope changed, and impacts confidentiality and integrity with no impact on availability.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'arrow' parameter. This can lead to unauthorized actions performed in the context of other users viewing the injected content, potentially compromising user data confidentiality and integrity. There is no direct impact on system availability. The vulnerability does not appear to be exploited in the wild at this time.

Patch status is not yet confirmed — no official fix or patch links are currently available. Users should monitor the vendor's advisory channels for updates and apply any forthcoming patches promptly. Until a patch is released, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the Post Grid widget if feasible.
