JSON 互操作性漏洞实验室 描述 这些是我研究文章《探索 JSON 互操作性漏洞》的配套实验室。 实验 1：电子商务应用中的免费购买 键碰撞攻击：重复键优先级不一致 大数表示不一致 实验 2：多租户应用中的权限提升 键碰撞攻击：字符截断 默认情况下，这些实验室绑定到主机的 5000-5004 端口。 攻击技术 1. 键碰撞 重复键优先级不一致 root@kitploit: "qty": 1, "qty": -1 字符截断 对于后键优先的解析器，会发生截断（对于前键优先的解析器，则需翻转顺序） root@kitploit: "qty": 1, "qty": -1 "qty": 1,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Keys: Fixed the issue of linking a duplicate key to a keyring’s assocarray. When making a DNS query within the kernel using dnsquery, the request code can, in rare cases, create a duplicate index key in the assocarray of the...

CVE-2026-50029

js-toml is a TOML parser for JavaScript, Prior to version 1.1.2, the interpreter checks whether a key already exists in a parser-built container with if objectkey instead of if key in object. When the prior value is a falsy primitive — false, 0, 0n, 0.0, -0, or "" — the duplicate-key branch is...

CVE-2026-50029

Affects js-toml prior to 1.1.2. The parser uses if (object[key]) to decide duplicates, causing falsy primitives (false, 0, 0n, 0.0, -0, "") to be overwritten by later keys; this yields structural type confusion in load() output (e.g., isAdmin becomes truthy object). MITRE/ATT&CK not specified in ...

js-yaml: Quadratic-complexity On^2 DoS via !!omap tag in YAML11SCHEMA...

CVE-2026-59870

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 before 5.2.1, YAML11SCHEMA support for the !!omap tag in src/tag/sequence/omap.ts uses omapTag.addItem to perform a linear duplicate-key scan on every insertion, causing On^2 CPU consumption when yaml.load parses a crafted ordered-map...

js-toml has silent type confusion via falsy-primitive duplicate-key bypass

Summary js-toml's interpreter checks whether a key already exists in a parser-built container with if objectkey instead of if key in object. When the prior value is a falsy primitive — false, 0, 0n, 0.0, -0, or "" — the duplicate-key branch is skipped and the value is silently overwritten by a...
