brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

CVE-2026-59881

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the WebSocket client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated, allowing a malicious server to cause unexpected CPU and memory...

CVE-2026-59881: Improper Input Validation

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the WebSocket client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated, allowing a malicious server to cause unexpected CPU and memory...

Inefficient Algorithmic Complexity

Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity through the cJSONCompare function. An attacker can cause excessive CPU consumption by submitting a deeply nested JSON document that is structurally equal to a reference document, leading to significant...

TencentOS Server 4: skopeo (TSSA-2026:0747)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0747 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

CVE-2026-5079

A flaw was found in Multer. A remote attacker can exploit this vulnerability by sending a single HTTP request with crafted multipart form data containing deeply nested field names. This can force the allocation of deeply nested object structures, consuming excessive CPU and memory resources. The...

CVE-2026-13074

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a...

CVE-2026-13064 MongoDB $jsonSchema Query Operator Excessive CPU Consumption Leading to Denial of Service

Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls...

Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls...

CVE-2026-13074 Awaitable Hello Command in Exhaust Mode Unthrottled Response Loop Leading to Denial of Service

An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a...

CVE-2026-63263: Uncontrolled Resource Consumption

Uncontrolled Resource Consumption CWE-400 in Elasticsearch can lead to denial of service via Exponential Data Expansion CAPEC-197. An authenticated user may submit a specially crafted query to the ES|QL engine that causes exponential CPU consumption during query evaluation. Because the resource...

CVE-2026-13069: Allocation of Resources Without Limits or Throttling

An authenticated user can cause excessive CPU consumption or out-of-memory conditions on a MongoDB server by sending a crafted Queryable Encryption find payload containing an unvalidated field used to control an internal computation loop. The resulting resource exhaustion degrades availability fo...

CVE-2026-13064: Inefficient Algorithmic Complexity

Certain query operations involving deeply nested $jsonSchema constructs can trigger disproportionate CPU consumption in affected MongoDB deployments, potentially leading to resource exhaustion. The resulting CPU-bound operation cannot be interrupted through standard administrative controls...

CVE-2026-63263

CVE-2026-63263 affects Elasticsearch’s ES|QL engine, where an authenticated user can submit a crafted query that triggers exponential CPU consumption during evaluation, causing uncontrolled resource exhaustion. The impact is denial of service as query worker resources become exhausted and ES|QL q...

AZL-93243 CVE-2026-59843 affecting package libssh for versions less than 0.10.6-9

A flaw was found in libssh. A remote authenticated peer can advertise a zero maximum packet size in SSHMSGCHANNELOPEN, causing later channel writes to loop indefinitely and consume CPU, leading to denial of service...
