CVE-2024-4036 is a stored cross-site scripting vulnerability in the Sydney Toolbox WordPress plugin (versions up to 1.30). The issue stems from improper neutralization of input in the style parameter, allowing authenticated users with contributor-level access or higher to inject arbitrary web scripts. These scripts execute in the context of any user accessing the compromised page, potentially leading to information disclosure or session hijacking. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (medium severity). No patch or official fix has been documented in the provided data.

Successful exploitation allows authenticated contributors or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no impact on availability. 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 and higher privileges to trusted users only to reduce risk. Monitor for updates from the vendor regarding patches or official mitigations.
