Hacktron chained a heap overflow in libheif to an OpenAI SSO flaw and opened a pull request in OpenAI's internal monorepo in under 72 hours. The bug had been fixed upstream a year earlier, but the fix never reached Debian's packages.

Hacktron chained a Claude-written libheif exploit into OpenAI's internal repositories

The libheif bug was fixed upstream a year earlier without a security label or a CVE, so a Discourse image check that ignored HEIC left it reachable, and forum sign-in tokens carried full API access to the accounts behind them.

An open-source gateway author walked Hacktron's five-step path into OpenAI through his own seven detection layers. The first two hops are requests to a forum and an identity provider. Where the gateway is deployed decides what any of it can read.

Two ordinary defects carried Hacktron from a forum image upload to OpenAI's internal monorepo

Hacktron's path into OpenAI's internal repos ran through a libheif bug Debian had not backported and a single sign-on flow that trusted community.openai.com. The dev.to breakdown says the model changed what the attack cost. The category of attack was the same either way.
