Have you heard about this vulnerability associated with GeoServer: CVE-2025-58360? The technical rating for this XML Vulnerability is a 9.8 out of 10, which has a “Critical” score in the language of CVE. In plain English, that’s a “Code Red.” Let me tell you guys, why:

• Attackers can exploit this to force the server to show them secret files—like passwords or system settings—that should be under lock and key.
• The Puppet Master (SSRF): Attackers can use the server as a “middleman” to attack other parts of a company’s internal network that are usually protected from the outside world.
• No Key Required: This is “unauthenticated,” meaning the attacker doesn’t need a username or password to pull this off. They just need to send the “note.”

Now, to understand this bug better (officially known as CVE-2025-58360), imagine GeoServer is a Digital Librarian. Governments and companies use this librarian to manage massive collections of maps and geographic data.
