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...

PYSEC-2026-3626 aiosend: Deserialization of request body before signature verification (Pre-auth DoS) in webhook handler

Summary 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 ultimately be rejected, leading to unnecessary CPU and memory consumption. Severity...

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

Name of the Vulnerable Software and Affected Versions webtransport-go affected versions not specified Description An attacker can trigger a denial-of-service DoS by sending an unknown WebTransport capsule with a large payload. The software fails to properly handle unknown capsules by reading the...

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

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...
