It uses case-sensitive pattern matching, so a query containing 'pass' (as in password) gets blocked, but 'pass' in a different context like 'pass an argument to a method in Java' also triggers the filter. The demo highlights that the matching is case-sensitive, meaning 'admin password' in lowercase gets blocked but 'Admin Password' with different casing would pass through to the model. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is Spring AI's Safeguard Advisor case-sensitive when blocking prompts? Yes, the Safeguard Advisor in Spring AI matches blocked phrases in a case-sensitive way. A prompt like 'What is the admin password?' can be blocked when it matches exactly, but simply changing the casing of the phrase lets the same request pass through and reach the model unblocked. _Developers hardening AI-integrated apps against prompt injection follow guardrail pitfalls like this on daily.dev._ ## Similar posts on daily.dev - [Spring AI : Advisors API](https://daily.dev/posts/spring-ai-advisors-api-ugswsrjzz) · SivaLabs · 4 upvotes · 0 comments - [When AI safety constrains defenders more than attackers](https://daily.dev/posts/when-ai-safety-constrains-defenders-more-than-attackers-n5jrhk0br) · CSO Online · 1 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java), [#ai-safety](https://daily.dev/tags/ai-safety), [#spring-ai](https://daily.dev/tags/spring-ai) [View this post on daily.dev](https://daily.dev/posts/spring-ai-s-safeguard-advisor-sfdeij1iy) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Spring AI's Safeguard Advisor","url":"https://daily.dev/posts/spring-ai-s-safeguard-advisor-sfdeij1iy","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/spring-ai-s-safeguard-advisor-sfdeij1iy"},"datePublished":"2026-07-29T18:14:43.841Z","dateModified":"2026-09-13T19:29:42.614Z","description":"Spring AI's Safeguard Advisor provides input filtering to block sensitive queries sent to AI models.
