In its first 30 days of research testing, it scanned over 1.2 million commits and identified more than 11,000 high-impact issues—792 critical and 10,561 high-severity—including 14 CVEs in projects like OpenSSH, PHP, and Chromium. Evolved from an internal tool called Aardvark, it is now available in research preview to ChatGPT Pro, Enterprise, Business, and Edu customers. ## Content OpenAI has launched Codex Security, an application security agent that scans codebases for vulnerabilities, validates them, and proposes patches. During its first 30 days of research testing, the tool scanned over 1.2 million commits and flagged more than 11,000 high-impact issues: 792 critical and 10,561 high-severity. It found bugs in open-source projects including OpenSSH, PHP, and Chromium, resulting in 14 CVEs. The difference from a traditional static scanner is that Codex Security tries to understand the full codebase rather than pattern-match on individual lines. It maps attack paths, confirms exploitability in a sandbox, and suggests fixes rather than just flagging suspicious code. The tool evolved from an internal project called Aardvark. It's now available in research preview to ChatGPT Pro, Enterprise, Business, and Edu customers. --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#appsec](https://daily.dev/tags/appsec), [#codex](https://daily.dev/tags/codex), [#openai](https://daily.dev/tags/openai) [View this post on daily.dev](https://daily.dev/posts/openai-launches-codex-security-for-enhanced-application-security-0rsqgeiou) ```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":"OpenAI Launches Codex Security for Enhanced Application Security","url":"https://daily.dev/posts/openai-launches-codex-security-for-enhanced-application-security-0rsqgeiou","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openai-launches-codex-security-for-enhanced-application-security-0rsqgeiou"},"datePublished":"2026-03-06T18:20:00.809Z","dateModified":"2026-03-15T07:49:37.703Z","description":"OpenAI has launched Codex Security, an AI-powered application security agent that goes beyond traditional static analysis by mapping full attack paths,...","isAccessibleForFree":true,"articleSection":"Collections","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collections","logo":"https://media.daily.dev/image/upload/s--fk_6ycEi--/f_auto,q_auto/v1780996001/logos/collections?_a=BAMAMiWQ0","url":"https://daily.dev/sources/collections"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/openai-launches-codex-security-for-enhanced-application-security-0rsqgeiou","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,appsec,codex,openai","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collections","item":"https://daily.dev/sources/collections"},{"@type":"ListItem","position":3,"name":"OpenAI Launches Codex Security for Enhanced Application Security"}]} ```
