Impact is memory-related and can affect systems process...

EUVD-2026-38351

Gophish through 0.12.1 contains a denial of service vulnerability that allows authenticated users with the User role to exhaust server memory by uploading a crafted Office document as an email template attachment. The ApplyTemplate function in models/attachment.go processes Office documents as ZI...

CVE-2026-39904

Gophish 0.12.1 is affected by a denial-of-service in the ApplyTemplate() path that processes Office documents as ZIP archives. The vulnerability arises from ioutil.ReadAll() on each file entry without sized limits, enabling a zip-bomb payload to cause several gigabytes of in-memory expansion and ...

CVE-2026-54277

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, it is possible to bypass the maxlinesize check in parts of an HTTP request in the C parser. If using the optimised C parser the default in pre-built wheels, then an attacker may be able to send...

CVE-2026-42127

The public dashboard query endpoint does not limit request body size before processing, allowing unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads. This can lead to denial of service through memory exhaustion. No valid dashboard access tok...

CVE-2026-54273

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This...

CVE-2026-54273

CVE-2026-54273 (AIOHTTP) affects the AIOHTTP project (async HTTP client/server for asyncio and Python). Prior to version 3.14.1, there was no limit on the number of pipelined HTTP/1 requests that could be queued, enabling potential memory exhaustion and DoS. The issue is fixed in 3.14.1. The prov...

CVE-2026-9320

IBM WebSphere Application Server 9.0, and 8.5 and IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.6 are vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory...

httpd: mod_md: unrestricted OCSP response leads to resource exhaustion

A flaw was found in the modmd module of httpd. When processing OCSP Online Certificate Status Protocol responses from a malicious or compromised OCSP responder, the module fails to enforce proper size limits on the incoming data. This issue leads to memory exhaustion and a denial of service...

httpd: HTTP/2: Remote Denial of Service via compression bomb and Slowloris-style attack

A flaw was found in HTTP/2, affecting various web servers. A remote attacker can exploit this vulnerability by combining an HPACK compression bomb with a zero-byte flow-control window. This technique allows a small amount of data to expand into large memory allocations on the server, which are th...
