CVE-2024-7356 is a stored cross-site scripting vulnerability (CWE-79) in the dylanjkotze Zephyr Project Manager WordPress plugin affecting all versions up to 3.3.100. The vulnerability exists due to improper neutralization of input in the 'filename' parameter, allowing authenticated users with Subscriber-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of other users viewing the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 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, scope change, and limited confidentiality and integrity impacts.

An attacker with at least Subscriber-level access can inject persistent malicious scripts via the 'filename' parameter, which execute when other users access the affected pages. This can lead to unauthorized actions performed in the context of the victim's session, including potential data theft or manipulation. The vulnerability does not impact availability. There are no reported exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Subscriber-level access to trusted users only and consider applying additional input validation or output escaping controls at the application or web server level if feasible. Monitor for updates from the plugin developer or WordPress security advisories.
