FacturaScripts blocked SVGs to prevent XSS but forgot about XML and HTML. Attackers can upload these file types containing malicious scripts. When an admin views the file, the script executes, leading to potential account takeover. Fixed in version 2025.7.
A stored Cross-Site Scripting (XSS) vulnerability in the FacturaScripts ERP system allows authenticated attackers to hijack administrator sessions by uploading malicious XML or HTML files.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
An unauthenticated remote denial of service vulnerability exists in the Unleash feature management platform. By submitting a crafted JSON payload containing deeply nested structures to an OpenAPI-validated endpoint, an attacker can trigger uncontrolled recursion within the error formatting module. This leads to a call-stack exhaustion (RangeError: Maximum call stack size exceeded) inside the Node.js runtime, causing the service to crash immediately without recovery.
CVE-2026-63004 is a server-side request forgery (SSRF) vulnerability in the Unleash feature management platform. Authenticated administrators with CREATE_ADDON or UPDATE_ADDON privileges can exploit this vulnerability to initiate requests to loopback addresses, private networks, and cloud metadata endpoints, potentially leading to information disclosure and credential extraction.
Prior to version 8.0.3, Unleash's Markdown event formatter directly mutated the global template-escaping function of the shared mustache Node.js module, resulting in a process-wide security degradation where HTML/Markdown escaping was permanently disabled for the application lifetime.
A critical SQL injection vulnerability exists in the GeoTools open-source Java library. This vulnerability is situated within the post-processing phase of OGC Filter conversion inside the PostGIS DataStore module. Specifically, the `jsonArrayContains` function does not validate or sanitize its arguments before constructing PostgreSQL SQL/JSON path evaluation queries. An unauthenticated remote attacker can exploit this weakness by submitting crafted filters via standard OGC services like WFS or WMS to execute arbitrary SQL commands on the underlying database system.
CVE-2026-61824 is a high-severity Cross-Site Scripting (XSS) vulnerability in kepano/defuddle before version 0.19.1. Custom site extractors for platforms such as X/Twitter, Substack, and YouTube constructed HTML representations via template string interpolation without output escaping. This allowed malicious pages to bypass standard parser sanitization routines and execute arbitrary JavaScript.
A high-severity vulnerability exists in KeystoneJS, a popular Node.js CMS and GraphQL framework, where the query resolution engine fails to validate signed negative integers within the pagination subsystem. Unauthenticated remote attackers can leverage this flaw to bypass the 'graphql.maxTake' safety boundary. By sending large negative values in the 'take' query parameter, the underlying Prisma ORM interprets the value as an instruction to fetch rows from the end of the collection, allowing malicious actors to bypass pagination limits, trigger database resource exhaustion, and execute application-level Denial of Service (DoS) attacks.
