CVE-2025-50690 — A Cross-Site Scripting (XSS) vulnerability exists in SpatialReference.org (OSGeo/spatialreference.org) versions prior to 2025-05-17...

Medium CVSS 6.1

A Cross-Site Scripting (XSS) vulnerability exists in SpatialReference.org (OSGeo/spatialreference.org) versions prior to 2025-05-17 (commit 2120adfa17ddd535bd0f539e6c4988fa3a2cb491). The vulnerability is caused by improper handling of user input in the search query parameter. An attacker can craft a specially formed URL with malicious JavaScript code, which is then reflected back and executed in the victim's browser. This flaw allows an attacker to execute arbitrary JavaScript in the context of the victim's session, potentially leading to session hijacking, phishing attacks, data theft, or redirection to malicious sites. The issue is exposed on publicly accessible pages, making it exploitable by an unauthenticated attacker.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
