1/ On July 25, 2026, the Hacktron AI team breached OpenAI in less than 72 hours.
They exploited 2 vulnerabilities to take over ChatGPT and Codex accounts belonging to some OpenAI employees and external users, and gained access to associated services like Outlook, Slack, and GitHub.
They also submitted a PR to OpenAI’s internal code repository, proving the attack’s success.
Full process👇
2/ 完整攻击链如下:
上传 HEIC/HEIF 图片 → ImageMagick 解码 → 触发 libheif 堆溢出 → 在 OpenAI 论坛实现 RCE → 利用 OpenAI SSO 漏洞 → 接管 ChatGPT、Codex 账户 → 访问关联的 GitHub → 向内部代码库提交 PR。
3/ 第一个漏洞来自图像处理库 libheif。
这个漏洞此前已经被上游修复,但没有被标记为安全问题,因此仍然存在于 Discourse 使用的版本中。
他们只需上传一个恶意 HEIF 文件,就能在 OpenAI 论坛 https://community.openai.com 上实现 RCE
4/ 第二个漏洞更加严重:OpenAI 的 SSO 存在关键问题。
他们利用这个漏洞,将 Discourse 论坛中的 RCE 进一步扩展到了 OpenAI 的其他服务。
5/ 任何曾经登录过该论坛的用户,都可能受到影响。
他们因此获得了部分 OpenAI 员工和外部用户的 ChatGPT、Codex 账户访问权限,还能继续进入与账户连接的其他服务。
6/ 为了证明漏洞影响,同时尽量减少数据暴露,他们只使用了一个关联 OpenAI GitHub 组织的员工账户。
Codex 在没有读取敏感代码的情况下,向 OpenAI 内部 Monorepo 创建了一个无害 PR。
这证明他们获得的访问权限是真实的。
7/ 他们分别向 Discourse 和 OpenAI 提交了漏洞报告。
OpenAI 在首次提交约 14 小时后修复了 SSO 问题。
Discourse 周六收到报告,周日回复,周一完成修复。
OpenAI 最终支付了 6500 美元漏洞奖金。
8/ AI Agent 完成了漏洞利用过程中的重要工作。
Opus 4.8 找到了 libheif 漏洞,并构建出部分利用代码。
Opus 5 发布几小时后,又将利用代码适配到 Discourse,成功在测试实例上实现 RCE。
9/ 他们得出的最大结论是:
AI 正在降低漏洞利用开发对稀缺安全专家经验的依赖。
过去需要几个月完成的工作,现在可能只需要几天。即使是领先的 AI 公司,也可能存在可被利用的漏洞。
10/ 防御方需要重新检查系统架构、更快安装补丁,并限制不同服务连接后可能产生的攻击范围。
这项研究由 Harsh Jaiswal 牵头,s1r1us 和 iamnoooob 共同参与。
完整技术细节:
11/ 他们还特别说明,自己并不是临时参与安全研究的普通用户。
此前,他们已经与 Perplexity、Vercel 等公司合作,并公开过多项安全研究成果。
12/ LiveOverflow 也制作了一期相关视频:
视频分析了他们如何利用一张恶意 HEIF 图片,完成这条针对 OpenAI 的攻击链。
13/ 在完成 OpenAI 的漏洞披露后,他们继续检查其他使用相同图像解析器的产品。
结果发现,这个漏洞还影响 Slack、Meta、GitHub Enterprise、Rails、Next.js、ImageMagick 等大量应用。
14/ 多家 AI 公司都在使用 Slack。
如果 Slack 遭到成功利用,攻击者理论上可能获取用户上传的私人图片和其他文件。
一个不起眼的底层图像库,可能同时成为大量应用的共同安全弱点。
