CVE-2026-15384— Manual Image Crop < 1.15 - Subscriber+ Arbitrary Attachment Image Overwrite via IDOR

Quick assessment

Affected
Unknown Manual Image Crop
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 插件 Manual Image Crop 在 1.15 版本之前，在对用于裁剪附件图片的已认证 AJAX 操作中没有执行任何权限检查或 Nonce 验证；其仅有的防护机制允许任何已登录用户通过验证。因此，具有订阅者（subscriber）级别权限的用户可以传入任意的附件 ID，从而覆盖该附件生成的中间尺寸图片（例如其缩略图），并篡改其存储的元数据，无论该媒体文件归属于哪位用户。这构成了媒体库中的跨用户完整性破坏/页面篡改问题。此外，该操作未设置 Nonce，因此还容易受到跨站请求伪造（CSRF）

Vulnerability Title
Manual Image Crop < 1.15 - Subscriber+ Arbitrary Attachment Image Overwrite via IDOR
Source: CVE Program / CVE List V5
Vulnerability Description
The Manual Image Crop WordPress plugin before 1.15 does not perform any capability check or nonce verification on the authenticated AJAX action that crops attachment images; its only guard passes for any logged-in user. A subscriber-level user can therefore supply an arbitrary attachment ID and overwrite that attachment's generated intermediate-size image (for example its thumbnail) and mutate its stored metadata, regardless of who owns the media. This is a cross-user integrity/defacement issue over the Media Library. The action also has no nonce, so it is additionally susceptible to CSRF.
