flat-to-nested: Prototype pollution in flat-to-nested convert() via __proto__ parent/id key

Summary convert builds the nested tree by using each flat record's id and parent field values directly as object keys, with no guard against proto / constructor / prototype. A record whose parent is the string "proto" makes tempparent resolve to Object.prototype, and the following initPush...

Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through recursive calls to the eachchild function when processing deeply nested input. An attacker can cause the process to crash and trigger a denial of service by supplying a specially crafted, deeply nested JSON...

Faraday: Uncontrolled recursion in NestedParamsEncoder allows stack exhaustion DoS via deeply nested query parameters

Faraday::NestedParamsEncoder, the default nested query parameter encoder/decoder in Faraday, decodes nested query strings without enforcing a maximum nesting depth. A crafted query string such as: text axxxx...x=1 causes Faraday to build a deeply nested Ruby Hash structure. The internal dehash...

Missing Authorization

Overview Affected versions of this package are vulnerable to Missing Authorization via the nested endpoint in the API controller. An attacker can access restricted and unpublished content by sending unauthenticated requests to the endpoint, which returns the full page tree including sensitive dat...

Inefficient Algorithmic Complexity

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity through the query-depth processing in validateQueryDepth and...

parse-server: Denial of service via exponential-time processing of deeply nested query operators

Impact Parse Server is vulnerable to denial of service. A remote attacker can send a single, small query 1 KB containing deeply nested query condition operators. Parse Server processes the nested structure with exponential time complexity, which blocks the Node.js event loop and makes the server...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86 – Check for nEPT/nNPT in slow flush hypercalls The check for isguestmodevcpus is incorrect, because the translatenestedgpa function is only valid if a L2 guest is running with nested EPT/NPT enabled. Instead, use the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM – Avoid clearing VMCBLBR in vmcb12. The svmcopylbrs function always marks VMCBLBR as dirty in the destination VMC. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing the “clean” bits in vmcb12 is not...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Stopping the IRR scan in kvmapicupdateirr even if PIR is empty The function apicfindhighestvector is used when PID.ON is set, but PIR turns out to be empty. This ensures that the highest pending interrupt from the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Raise UD if the unhandled VMMCALL is not intercepted by L1. If L2 is active, and L1 does not want to intercept VMMCALL, and nestedsvml2tlbflush is enabled, and the hypercall is something other than one of the supported...
