Hacktron chained an image-library bug in OpenAI's Discourse forum to a single sign-on misconfiguration, reached employee ChatGPT and Codex accounts inside 72 hours, and the repair OpenAI describes is a narrowing of token permissions.

Hacktron AI chained a Discourse image-library flaw to a weakness in OpenAI's single sign-on and into the Codex environment in under 72 hours, after swapping Claude Opus 4.8 for Opus 5 to get a working exploit.

buildOne report1 publisher Hacktron chained an unflagged libheif overflow to write access on OpenAI's monorepo
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.

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.

CVE-2026-75604 hands unauthenticated RCE to anyone reaching a Windows-hosted Next.js app
The affected releases stretch back to Next.js 13.4, and for Windows self-hosters the only remedy Vercel offers is the version bump. The AVIF bug shipped in the same release at least has a config gate.

The image parsing bug had been fixed upstream about a year earlier, and the decision not to ship that fix belonged to Discourse. OpenAI's forum shared single sign-on with internal systems, so a forum account became GitHub access.

libheif 1.23.5 blocks a 351-byte AVIF that forced allocations of more than 10 GB
libheif v1.23.5 fixes a high-rated flaw that let a 351-byte AVIF file force decoder allocations of more than 10 GB. It is a drop-in replacement for v1.23.4 and also closes six lower-rated memory-handling bugs.

buildOne report1 publisher A prompt gateway would need to track multi-turn conversation context to catch Hacktron's OpenAI chain
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.

buildOne report1 publisher Hacktron chained a libheif bug on OpenAI's forum into internal GitHub repositories
Hacktron's report puts the vulnerable code in libheif, two dependency steps below an ImageMagick call on OpenAI's Discourse forum, and says the upstream fix never went through the usual security advisory process.

One independent developer fixed 37 libheif and libde265 security advisories in 2026
The project's own README puts the 2026 advisory count at 37 and the maintenance roster at one independent developer with almost no recurring funding. Products that decode HEIC or AVIF inherit that pace.

buildOne report1 publisher 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.

buildOne report1 publisher canvas.toBlob hands you a PNG and calls it WebP: check blob.type, not the user agent
