Slow-proofed and worth the wait. Worth its weight in flour.
Summary
A security researcher reports on two security vulnerabilities discovered in Okta's auth0/nextjs-auth0 project, including an OAuth parameter injection bug that could allow token leakage and abuse. The researcher submitted a patch via pull request, but after 3 weeks, the maintainer (an Auth0/Okt employee) closed the PR, claiming it was superseded by another PR. The article discusses the broader issue of AI-generated code and maintenance problems in software engineering, highlighting how AI hallucinations and misattribution can lead to broken code and security issues in critical authentication libraries.
