Arcjet has released AI Prompt Injection Protection, a new capability designed to stop prompt injection attacks before they reach production AI models. The feature detects hostile prompts at the application boundary and gives developers a decision point inside the request lifecycle where malicious instructions can be blocked before inference occurs.

As those systems gain access to data, tools, and expensive model endpoints, the security problem shifts from filtering bad text to enforcing policy inside the request lifecycle using real application context.

CISA has ordered U.S. government agencies to secure their servers against an actively exploited vulnerability in the Zimbra Collaboration Suite (ZCS). Zimbra is a very popular email and collaboration software suite used by hundreds of millions of people worldwide, including thousands of businesses and hundreds of government agencies. Tracked as CVE-2025-66376 and patched in early November, this high-severity security flaw stems from a stored cross-site scripting (XSS) weakness in the Classic UI that remote unauthenticated attackers could exploit by abusing Cascading Style Sheets (CSS) @import directives in email HTML. While Synacor (the company behind Zimbra) didn’t share any details on…
