The woocommerce-pdf-invoices-packing-slips plugin before 2.0.13 for WordPress has XSS via the tab or section variable on settings screens.

InvoicePlane 1.5 has stored XSS via the index.php/invoices/ajax/save invoice_password parameter, aka the "PDF password" field to the "Create Invoice" option. The XSS payload is rendered at an index.php/invoices/view/## URI. NOTE: this is different from CVE-2018-12255.

Spring Framework, version 5.1, versions 5.0.x prior to 5.0.10, versions 4.3.x prior to 4.3.20, and older unsupported versions on the 4.2.x branch provide support for range requests when serving static resources through the ResourceHttpRequestHandler, or starting in 5.0 when an annotated controller returns an org.springframework.core.io.Resource. A malicious user (or attacker) can add a range header with a high number of ranges, or with wide ranges that overlap, or both, for a denial of service attack. This vulnerability affects applications that depend on either spring-webmvc or spring-webflux. Such applications must also have a registration for serving static resources (e.g. JS, CSS, images, and others), or have an annotated controller that returns an org.springframework.core.io.Resource. Spring Boot applications that depend on spring-boot-starter-web or spring-boot-starter-webflux are ready to serve static resources out of the box and are therefore vulnerable.

paypal/invoice-sdk-php is vulnerable to reflected XSS in samples/permissions.php via the permToken parameter, resulting in code execution.
