涵盖 bikini/exploitarium 匿名披露的 Microsoft Sentinel 和 Defender XDR KQL 检测规则——这是一个包含 15+ 个不同漏洞目标的个人研究档案，涉及 109+ 个跟踪文件，于 2026 年 6 月 23 日未经厂商通知发布。

一位名为 'bikini' 的匿名研究人员发布了 exploitarium，这是一个 GitHub 仓库，包含针对 15+ 个不同漏洞目标的概念验证研究（15+ 个文件夹中的 109+ 个跟踪文件）。该仓库正在积极更新——研究人员持续发布新作品，因此不断有新条目加入。
范围说明: 该仓库包含 15 个不同的漏洞研究目标。每个文件夹的文件数量反映的是单个文件（脚本、载荷、辅助工具、README），而非不同的 CVE。研究人员的 README 指出，这些漏洞在发布时尚未报告，并明确邀请其他人提交 CVE。
其中技术意义最重大的发现——libssh2 预认证堆写入和 Gitea 默认 Docker 认证绕过——已被独立验证为高风险，并已观察到积极利用。社区已将某些条目视为低影响噪音并予以忽视。
