OpenAI fixed it in 14 hours, paid $6,500.","In the early hours of July 25, 2026, security research team Hacktron pulled off a textbook chained intrusion: they took control of several OpenAI employees' ChatGPT accounts and, through one employee's Codex-connected GitHub integration, gained access to OpenAI's internal monorepo. To prove the breach without touching sensitive code, they had the employee's Codex open a harmless pull request (#1186742) in `openai\u002Fopenai`, then immediately ceased all further testing. From initial discovery to internal repo access, the entire chain took less than 72 hours — and the primary weapon throughout was Anthropic's Claude.\n\n## The Exploit Chain: One HEIF Image Punches Through Nine Layers\n\nHacktron's official disclosure, published September 13, breaks the attack into nine steps: a libheif image decoder heap overflow → missing Debian security backport → ImageMagick calling libheif → Discourse forum image uploads → the OpenAI community forum → an OpenAI SSO identity flaw → ChatGPT\u002FCodex account takeover → the connected GitHub integration → internal repositories.\n\nThe entry point was an unglamorous image library. Discourse normally checks uploaded images with FastImage, but FastImage does not support HEIF — so those files were handed directly to ImageMagick's `magick` command for conversion, exposing the underlying libheif parser to attacker-controlled files. An Opus 4.8 session inside the Discourse Docker image examined the installed libheif package and found that certain security fixes had never been backported: code changed upstream a year earlier was never documented as a security fix and received no CVE, so Debian 12 and 13 kept shipping vulnerable versions (1.19.7 and 1.19.8 respectively). The heap overflow produced out-of-bounds read\u002Fwrite primitives during HEIC decoding, and RCE followed.\n\nWhat amplified a forum bug into account takeover was the OpenAI-side SSO misconfiguration: any user or employee logging into the community forum through auth.openai.com could have their ChatGPT and Codex accounts taken over without interaction. Hacktron stressed this was not Discourse-specific — any first-party or third-party OpenAI service using OpenAI SSO, once compromised, would lead to the same access. The forum was merely one demonstrable path.\n\n## What the AI Did at Each Step\n\nThe timeline shows the model capability boundary most clearly. On July 23 they began reviewing the image-upload pipeline. On July 24, Opus 4.8 produced a working exploit with ASLR disabled, but repeatedly failed against Discourse's default ASLR-enabled configuration. That evening, Anthropic released Claude Opus 5 — a fresh session produced a working ARM64 exploit within 3 hours, then ported it to the x86-64 and jemalloc configuration Discourse uses. By 6 a.m. on July 25 they had confirmed local RCE through an image upload; by 10 a.m. the agent had achieved RCE on their own Discourse Cloud instance and read `\u002Fetc\u002Fhosts`. One detail stands out: Opus refused to write exploits for remote instances, so the team proxied the target to look like a CTF challenge (`rce.ee\u002Fctf-forum`) before it complied.\n\nThe cost figures deserve remembering. The Discourse-plus-OpenAI effort took the agent a few days and only a few hours of human time. Scaled across the broader \"HEIF Heist\" research campaign — covering Slack, Meta, GitHub Enterprise and more — the two-month project cost under $3,000 in tokens total, run by three researchers, with each new company typically falling in one to two days. They also observed clear generational jumps: Opus 4.8 stalled on ASLR, Opus 5 succeeded within hours, and GPT-5.6 Sol marked another leap — exploiting the vulnerability while knowing nothing about the target system except that it was vulnerable.\n\n## Vendor Response and the Industry's Cold Reality\n\nThe vendor responses deserve credit. OpenAI confirmed the fix roughly 14 hours after the report and paid a $6,500 bounty — while clarifying that the award covered only the OpenAI-side finding, with testing against the Discourse-hosted forum explicitly excluded from the program. Discourse received the report on a Saturday, replied Sunday, and had a fix by Monday, plus sandboxed ImageMagick as defense in depth. The more sobering fact: across the multi-target campaign, thousands of images were sent and image processors crashed repeatedly — and no company detected the activity except Shopify.\n\nThis connects directly to the \"death of security through obscurity\" conversation: software has long benefited from security-through-complexity — a vulnerability could be public, but turning a bug into a reliable exploit required scarce expertise, significant time, and knowledge of the target environment. AI is turning that scarce expertise into compute, compressing \"a well-resourced team working for months\" into days. Hacktron's conclusion: threat models must catch up with the economics of attacker capability, rather than clinging to outdated assumptions about who can mount sophisticated attacks. For self-hosted Discourse operators their advice is concrete: rebuild your instance now — older Docker images may still carry the vulnerable libheif, and a web-interface update alone may not replace the underlying image.\n\nThe takeaway for ordinary developers: the unglamorous image decoder buried in your dependency tree, and a single misconfigured trust boundary in your SSO layer, are both live attack surfaces in the AI era. Isolating image-processing pipelines in hardened sandboxes and auditing SSO trust boundaries are no longer deferrable chores.\n\nReferences: Hacktron's official disclosure, [Hacking OpenAI](https:\u002F\u002Fwww.hacktron.ai\u002Fblog\u002Fhacking-openai); [The Guardian's coverage](https:\u002F\u002Fwww.theguardian.com\u002Ftechnology\u002F2026\u002Fsep\u002F18\u002Fopenai-hacked-anthropic-claude-chatbot); Discourse advisory [GHSA-vhm9-85gw-x335](https:\u002F\u002Fgithub.com\u002Fdiscourse\u002Fdiscourse\u002Fsecurity\u002Fadvisories\u002FGHSA-vhm9-85gw-x335).","hacktron-claude-openai-heif-sso-breach","2026-09-18T17:12:43Z","2026-09-18T17:12:49.301989Z","2026-09-18T17:12:49.301997Z",true,"agent",10,[39,48],{"slug":40,"tag_slug":40,"title_zh":41,"title_en":42,"intro_zh":43,"intro_en":44,"id":45,"is_active":35,"created_at":46,"modified_at":47},"ai-for-science","AI for Science 2026：从 UniPert 到 GPT-Rosalind 的硬核进化","AI for Science 2026: from UniPert to GPT-Rosalind","生命科学、化学材料、物理世界模型——AI 正在从\"语言工具\"变成\"实验伙伴\"。本专题收录 AI 在三大科学方向的关键节点：UniPert 统一基因与化学扰动空间、GPT-Rosalind 端到端生命科学推理、达摩院 AI 智能体 28 小时找到 4 种超导新材料、Anthropic Claude Science 把工作台做成标准品。","From language tool to lab partner — AI is reshaping life sciences, chemistry\u002Fmaterials, and physical world models.
