grafana: Grafana: Denial of Service via excessive memory allocation from large API request payloads

A flaw in Grafana's API endpoints allows remote attackers to send excessively large request bodies without authentication. This exhausts server memory, resulting in a complete denial of service DoS...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. Variable names present in the supplied command line are expanded into their corresponding variable contents, using a 1 kB stack buffer for temporary storage. However, there is insufficient bounds checking. If the function is called with a...

EUVD-2026-53920

aiosend is a synchronous and asynchronous Crypto Pay API client. Pror to version 3.0.7, WebhookHandler.feedupdate deserializes the entire request body before verifying the HMAC signature. This allows an unauthenticated attacker to force expensive parsing of arbitrary JSON payloads that will...

The version of Grafana Labs installed on the remote host is affected by multiple vulnerabilities, including: - The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily...

PT-2026-64438

Summary An attacker can cause excessive memory allocation in webtransport-go by sending an unknown WebTransport capsule with a large payload. The implementation skips unknown capsules by reading the entire capsule body into memory, instead of draining it without retaining the data. This can lead ...

SUSE CVE-2026-56816

Netty is a network application framework for development of protocol servers and clients. Prior to 4.2.16.Final, Netty's Http3FrameCodec buffers incoming data for HTTP/3 reserved frame types up to the wire-specified payload length without limits; decodeFrame trusts payLoadLength, allowing an...

Uncontrolled Resource Consumption

github.com/zalando/skipper is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to reading the entire admission webhook request body without enforcing a size limit, which allows an attacker to send excessively large payloads and exhaust memory, resulting in a...

CVE-2026-12478

The fix for CVE-2026-0716 commit 6ff7ef0, libsoup 3.6.6 placed the integer overflow guard inside the if masked block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64MAX to trigger an OOB read in...

BIT-GRAFANA-2026-33382 Denial of service via unbounded request body size

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service...

CVE-2026-33382 Denial of service via unbounded request body size

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service...

PT-2026-57205

Name of the Vulnerable Software and Affected Versions Grafana affected versions not specified Description Several API endpoints, some of which are unauthenticated, fail to limit the size of the request body before processing. This allows an attacker to send excessively large payloads that trigger...

CVE-2026-12590

A flaw was found in body-parser. When the parser is configured with an invalid limit option, such as an unparseable string or a non-numeric value, the request body size check is bypassed. This allows a remote attacker to send arbitrarily large payloads, consuming excessive memory and CPU resource...

PYSEC-2026-1100 AIOHTTP vulnerable to denial of service through large payloads

Summary A request can be crafted in such a way that an aiohttp server's memory fills up uncontrollably during processing. Impact If an application includes a handler that uses the Request.post method, an attacker may be able to freeze the server by exhausting the memory. ----- Patch:...

Open WebUI lacks authentication for the `api/v1/utils/pdf` endpoint

In version v0.3.10 of open-webui/open-webui, the api/v1/utils/pdf endpoint lacks authentication mechanisms, allowing unauthenticated attackers to access the PDF generation service. This vulnerability can be exploited by sending a POST request with an excessively large payload, potentially leading...
