CVE-2025-4608 is a stored cross-site scripting vulnerability in the gorbo Structured Content (JSON-LD) WordPress plugin, affecting all versions up to 1.6.4. The issue arises from improper neutralization of input during web page generation, specifically in the sc_fs_local_business shortcode, allowing authenticated users with contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users viewing the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity with no availability impact. No known exploits in the wild or vendor patches are currently documented.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user data confidentiality and integrity. The vulnerability does not impact availability. The scope is changed (S:C), meaning the attack can affect resources beyond the attacker’s privileges. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the Structured Content plugin if feasible. Monitor for updates from the vendor or WordPress plugin repository for a security patch.
