dovecot: Fix of CVE-2026-27857
CVE-2026-27857: imap-login: limit IMAP parser open lists to prevent excessive memory usage...
UBUNTU-CVE-2026-8199
An authenticated user can cause excess memory usage via bitwise match expression AST processing of $bitsAllSet, $bitsAnySet, $bitsAllClear, and $bitsAnyClear. This contributes to memory pressure and may lead to availability loss by OOM. This issue impacts MongoDB Server v7.0 versions prior to...
CVE-2026-44248: Uncontrolled Resource Consumption
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader method is called before the...
Denial of Service (DoS)
Overview magento/community-edition is a modern cloud eCommerce platform. Affected versions of this package are vulnerable to Denial of Service DoS through the handling of resource requests. An attacker can cause the application to become unresponsive by sending specially crafted requests that...
CVE-2026-42006
An attacker can cause uncontrolled memory usage with excessive bracing over IMAP. The fix in CVE-2026-27857 was incomplete, only blocking one way of doing this, so there was still another way left open. In particular, the fix was for closing braces, but you could still use open braces to bypass t...

zeek -- potential DoS vulnerability
Wojtulewicz of Corelight reports: A specially-crafted series of MIME headers sent via SMTP or HTTP could cause Zeek to use large amounts of memory and potentially crash...
BIT-LIBPYTHON-2025-13836 Excessive read buffering DoS in http.client
When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS...
urllib3: Decompression-bomb safeguards bypassed in parts of the streaming API
Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or...

CVE-2025-10470
The Magic Link authentication flow accepts multiple invalid authentication requests without adequate rate limiting or resource control, leading to uncontrolled memory usage growth. This vulnerability can result in a denial-of-service condition, causing service unavailability for deployments that...
urllib3: urllib3: Denial of Service due to excessive HTTP response decompression
A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response,...
