The package provides two middleware classes: InjectionGuard (detects and blocks prompt injection attempts) and PersonalInformationRedactor (masks PII like emails, phone numbers, API keys, and bearer tokens before they reach AI providers like OpenAI). Three demo scenarios are shown: a support chatbot, an email triage agent, and a log analysis agent. The middleware can be configured to either block or redact flagged content. A caveat is noted that the package uses regex-based detection, which won't catch sophisticated injection attacks, so it should not be treated as a complete security solution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does the Intercept package for Laravel AI SDK work with the latest Laravel AI SDK 0.9? No, compatibility issues currently prevent it from working with Laravel AI SDK 0.9, requiring a downgrade to version 0.8 to function properly. The package requires PHP 8.4 and Laravel AI SDK, and this incompatibility with the newest SDK release is expected to be fixed soon. _daily.dev helps developers track compatibility fixes before upgrading Laravel AI SDK packages._ ### How can I prevent sensitive data like emails and API keys from being sent to OpenAI in a Laravel AI agent? Middleware classes such as InjectionGuard and PersonalInformationRedactor from the Intercept package can redact or block sensitive data like emails, phone numbers, API keys, and bearer tokens before requests reach OpenAI or Anthropic. Developers choose either a redact action, which masks the data, or a block action, which stops the request from reaching the provider entirely. _Developers securing AI agent pipelines can find middleware patterns like this through daily.dev._ ### How does regex-based prompt injection detection work in Laravel middleware and what are its limitations? It works by matching regular expressions against obvious patterns like phrases telling the model to ignore previous instructions or reveal its system prompt, then flagging or blocking the message before it reaches the AI provider. This approach only catches known patterns and cannot be treated as a complete security solution, since attackers continue finding more sophisticated ways to bypass simple pattern-based guards. _daily.dev surfaces practical limitations like this for teams evaluating prompt injection defenses._ ## Similar posts on daily.dev - [Prompt-Injection Guardrails in Laravel: Defend the Tools, Not the Prompt](https://daily.dev/posts/prompt-injection-guardrails-in-laravel-defend-the-tools-not-the-prompt-kltttny27) · FREEK.DEV · 2 upvotes · 0 comments - [Ship AI with Laravel: I Tricked My Own AI Into Leaking Everything](https://daily.dev/posts/ship-ai-with-laravel-i-tricked-my-own-ai-into-leaking-everything-wpii6pnlw) · Laravel News · 0 upvotes · 0 comments - [Medium](https://daily.dev/posts/medium-bse1kypnf) · Medium · 0 upvotes · 0 comments --- Tags: [#php](https://daily.dev/tags/php), [#openai](https://daily.dev/tags/openai), [#laravel](https://daily.dev/tags/laravel), [#ai-security](https://daily.dev/tags/ai-security), [#prompt-injection](https://daily.dev/tags/prompt-injection) [View this post on daily.dev](https://daily.dev/posts/laravel-package-intercept-protect-from-prompt-injection-in-ai-sdk-btxljagha) ```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":"Laravel Package Intercept: Protect from Prompt Injection in AI SDK","url":"https://daily.dev/posts/laravel-package-intercept-protect-from-prompt-injection-in-ai-sdk-btxljagha","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/laravel-package-intercept-protect-from-prompt-injection-in-ai-sdk-btxljagha"},"datePublished":"2026-07-13T06:07:49.216Z","dateModified":"2026-09-13T19:39:56.113Z","description":"A Laravel package called 'Intercept' adds security middleware to the Laravel AI SDK to protect against prompt injection attacks and sensitive data leakage.
