Resource-Exhaustion

A resource exhaustion vulnerability, CVE-2026-11605, affects specific versions of ISC BIND 9, where DNSSEC validation disproportionately consumes CPU resources when processing superfluous RRSIG records, potentially leading to a denial of service.

A vulnerability (CVE-2026-23538) exists in the Feast Feature Server's /ws/chat endpoint, allowing remote attackers to establish numerous unauthenticated, persistent WebSocket connections. This exploit, a form of resource exhaustion (CWE-770), consumes server resources like memory, CPU, and file descriptors, leading to a complete denial of service for legitimate users. Affected versions are those prior to 0.59.0.

A critical vulnerability, CVE-2026-48594, in the Tesla Elixir HTTP client library allows an attacker to cause a denial of service by serving a specially crafted HTTP response with multiple `content-encoding` headers that, when processed by vulnerable versions (0.6.0 through 1.18.2) of the client using `Tesla.Middleware.DecompressResponse` or `Tesla.Middleware.Compression`, leads to exponential memory expansion and application crashes.

SQLFluff versions prior to 4.2.0 are vulnerable to uncontrolled resource consumption (CVE-2026-46374), allowing an attacker to cause a denial of service by submitting a maliciously crafted, long SQL query.

Adobe Commerce versions 2.4.9-beta1, 2.4.8-p4, 2.4.7-p9, 2.4.6-p14, 2.4.5-p16, 2.4.4-p17 and earlier are susceptible to an uncontrolled resource consumption vulnerability (CVE-2026-34650) that allows an unauthenticated attacker to cause a denial-of-service condition by exhausting system resources.

Siemens SIMATIC CN 4100 versions before V5.0 are vulnerable to resource exhaustion due to processing a high volume of TCP SYN packets, leading to a denial-of-service condition.

Siemens SIMATIC CN 4100 versions before V5.0 are vulnerable to resource exhaustion due to improper restriction of unauthenticated connections, potentially leading to disruption of operations and unauthorized actions.

Netty's Lz4FrameDecoder is vulnerable to resource exhaustion, where an attacker can cause excessive memory allocation by sending a small, crafted header, leading to a denial-of-service condition; this affects netty-codec-compression versions up to 4.2.12.Final and netty-codec versions up to 4.1.132.Final.

Netty's epoll transport fails to properly close TCP connections that receive a RST after a half-close, leading to resource exhaustion and potential CPU busy-loops, impacting service availability.

The `OverlappingFieldsCanBeMerged` validation rule in `webonyx/graphql-php` has an `O(n^2 x m^2)` worst-case complexity due to flattened inline fragments, leading to potential resource exhaustion.

The Contact Form 7 WordPress plugin through version 2.6.7 is vulnerable to uncontrolled resource consumption, allowing unauthenticated attackers to exhaust server memory and crash the PHP process by supplying an arbitrarily large integer value to the REST API endpoint, leading to unbounded loop execution.

OpenClaw before 2026.3.31 parses MS Teams webhook request bodies before performing JWT validation, allowing unauthenticated attackers to exhaust server resources by sending malicious Teams webhook payloads.

A vulnerability exists in Progress Telerik UI for AJAX prior to 2026.1.421, RadAsyncUpload, due to missing cumulative size enforcement during chunk reassembly, which allows file uploads to exceed the configured maximum size, leading to disk space exhaustion.

Multiple defense-in-depth gaps exist in Meridian versions prior to 2.1.1, including high severity issues related to bypassing safety caps on collection mapping that can lead to resource exhaustion, along with medium and low severity issues affecting constructor selection, telemetry, retry mechanisms, and exception handling.

PraisonAI before version 4.5.128 is vulnerable to resource exhaustion and API credit draining due to the `/media-stream` WebSocket endpoint accepting unauthenticated connections, allowing attackers to exhaust server resources and drain OpenAI API credits.

Unauthenticated attackers can exploit a resource exhaustion vulnerability (CVE-2026-33756) in Saleor e-commerce platform versions before 3.23.0a3, 3.22.47, 3.21.54, and 3.20.118 by sending a single HTTP request with a large number of GraphQL operations, bypassing query complexity limits and exhausting server resources.

A remote, unauthenticated attacker can cause resource exhaustion in Saleor e-commerce platforms via maliciously crafted GraphQL API requests, leading to denial of service.

This brief covers a technique to detect resource exhaustion attacks against Ollama servers by monitoring abnormal memory allocation and runner operations, potentially leading to denial of service or performance degradation.
