The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the logout-url shortcode's 'button' attribute in all versions up to, and including, 8.2.36 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The PeproDev WooCommerce Receipt Uploader WordPress plugin through 2.8.0 does not verify that a requested attachment belongs to the order referenced by its access token, allowing unauthenticated attackers to forge a token and disclose image attachments, including other customers' uploaded payment receipts, that they do not own.

The PeproDev Ultimate Invoice WordPress plugin through 2.2.5 has a bulk download invoices action that generates ZIP archives containing exported invoice PDFs. The ZIP files are named predictably making it possible to brute force and retreive PII.

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the handelajaxreq() function in versions 1.9.1 to 7.5.2. This makes it possible for unauthenticated attackers to update arbitrary user's metadata which can be leveraged to block an administrator from accessing their site when wpcapabilities is set to 0.

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Authentication Bypass in versions 1.9.1 to 7.5.2. This is due to handelajaxreq() function not having proper restrictions on the changeusermeta functionality that makes it possible to set a OTP code and subsequently log in with that OTP code. This makes it possible for unauthenticated attackers to login as other users on the site, including administrators.

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to unauthorized access of data via its publicly exposed reset-password endpoint. The plugin looks up the 'validemail' value based solely on a supplied username parameter, without verifying that the requester is associated with that user account. This allows unauthenticated attackers to enumerate email addresses for any user, including administrators.

The PeproDev Ultimate Invoice plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.9 via the invoicing viewer due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view invoices for completed orders which can contain PII of users.

The PeproDev WooCommerce Receipt Uploader plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of addqueryarg without appropriate escaping on the URL in all versions up to, and including, 2.6.9. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE-2025-24574 is likely a duplicate of this issue.
