CVE-2026-42006 2 Dovecot, Open-xchange 3 Dovecot, Dovecot, Ox Dovecot Pro 2026-05-18 4.3 Medium
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 the limit. Using excessive bracing, attacker can cause memory usage up to configured memory limit. Install fixed version, or configure vsz_limit for imap process to low value. No publicly available exploits are known.
CVE-2026-42579 1 Netty 1 Netty 2026-05-18 7.5 High
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's DNS codec does not enforce RFC 1035 domain name constraints during either encoding or decoding. This creates a bidirectional attack surface: malicious DNS responses can exploit the decoder, and user-influenced hostnames can exploit the encoder. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
CVE-2026-42544 1 Emmett-framework 1 Granian 2026-05-18 7.5 High
Granian is a Rust HTTP server for Python applications. From 1.2.0 to 2.7.4, Granian aborts a worker process when an unauthenticated client sends a WebSocket upgrade request whose Sec-WebSocket-Protocol header contains non-ASCII bytes. The crash happens in Granian's WebSocket scope construction path, before the ASGI application is invoked. This vulnerability is fixed in 2.7.4.
CVE-2026-42583 2 Io.netty, Netty 3 Netty-codec, Netty-codec-compression, Netty 2026-05-18 7.5 High
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength (up to 32 MB per block) before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload bytes - 22 bytes if compressedLength == 1 - to force that allocation. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
CVE-2026-42587 2 Io.netty, Netty 3 Netty-codec-http, Netty-codec-http2, Netty 2026-05-18 7.5 High
Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate encodings via ZlibDecoder, but is silently ignored when the content encoding is br (Brotli), zstd, or snappy. An attacker can bypass the configured decompression limit by sending a compressed payload with Content-Encoding: br instead of Content-Encoding: gzip, causing unbounded memory allocation and out-of-memory denial of service. The same vulnerability exists in DelegatingDecompressorFrameListener for HTTP/2 connections. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
CVE-2026-44248 2 Io.netty, Netty 2 Netty-codec-mqtt, Netty 2026-05-18 5.3 Medium
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 bytesRemainingBeforeVariableHeader > maxBytesInMessage check. The decodeVariableHeader() can call other methods which will call decodeProperties(). Effectively, Netty does not apply any limits to the size of the properties being decoded. Additionally, because MqttDecoder extends ReplayingDecoder, Netty will repeatedly re-parse the enormous Properties sections and buffer the bytes in memory, until the entire thing parses to completion. This can cause high resource usage in both CPU and memory. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
CVE-2026-38728 1 Nodemailer 1 Smtp Server 2026-05-17 7.5 High
An issue in Nodemailer smtp_server before v.3.18.3 allows a remote attacker to cause a denial of service via the SMTPStream._write, lib/smtp-stream.js components

CVE-2026-23824 2 Arubanetworks, Hpe 3 Arubaos, Sd-wan, Arubaos 2026-05-15 7.5 High
Vulnerabilities exist in a protocol-handling component of AOS-8 and AOS-10 Operating Systems. An unauthenticated attacker could exploit these vulnerabilities by sending specially crafted network messages to the affected service. Due to insufficient input validation, successful exploitation may terminate a critical system process, resulting in a denial-of-service condition.
CVE-2026-44167 1 Phpseclib 1 Phpseclib 2026-05-14 7.5 High
phpseclib is a PHP secure communications library. Prior to 1.0.29, 2.0.54, and 3.0.52, anyone loading untrusted ASN1 files (eg. X509 certificates, RSA PKCS8 private or public keys, etc). This is a bypass of CVE-2024-27355. This vulnerability is fixed in 1.0.29, 2.0.54, and 3.0.52.
CVE-2026-20188 1 Cisco 2 Crosswork Network Automation, Network Services Orchestrator 2026-05-14 0 Low
Following the initial publication of the Security Advisory about a denial of service (DoS) condition in Cisco Crosswork Network Controller and Cisco Network Services Orchestrator (NSO), additional information has been made available to the Cisco Product Security Incident Response Team (PSIRT). Upon further analysis, the Cisco PSIRT has reclassified this issue as a customer-configurable, resource management issue rather than a security vulnerability.
CVE-2026-44240 1 Patrickjuchli 1 Basic-ftp 2026-05-14 7.5 High
basic-ftp is an FTP client for Node.js. Prior to 5.3.1, basic-ftp is vulnerable to client-side denial of service when parsing FTP control-channel multiline responses. A malicious or compromised FTP server can send an unterminated multiline response during the initial FTP banner phase, before authentication. The client keeps appending attacker-controlled data into FtpContext._partialResponse and repeatedly reparses the accumulated buffer without enforcing a maximum control response size. As a result, an application using basic-ftp can remain stuck in connect() while memory and CPU usage grow under attacker-controlled input. This can lead to process-level denial of service, container OOM kills, worker restarts, queue backlog, or service degradation in applications that automatically connect to FTP endpoints. This vulnerability is fixed in 5.3.1.
CVE-2024-0241 1 Diaconou 1 Encodedid\ 2026-05-14 7.5 High
encoded_id-rails versions before 1.0.0.beta2 are affected by an uncontrolled resource consumption vulnerability. A remote and unauthenticated attacker might cause a denial of service condition by sending an HTTP request with an extremely long "id" parameter.
CVE-2026-44456 1 Hono 1 Hono 2026-05-13 6.5 Medium
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.16, bodyLimit() does not reliably enforce maxSize for requests without a usable Content-Length (e.g. Transfer-Encoding: chunked). Oversized requests can reach handlers and return 200 instead of 413. This vulnerability is fixed in 4.12.16.
CVE-2026-44241 1 Micronaut-projects 1 Micronaut-core 2026-05-13 7.5 High
Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. From 4.3.0 to before 4.10.22, TimeConverterRegistrar caches DateTimeFormatter instances in an unbounded ConcurrentHashMap<String, DateTimeFormatter> whose key is derived from the @Format annotation pattern concatenated with the locale from the HTTP Accept-Language header. Because Locale.forLanguageTag() accepts arbitrary BCP 47 private-use extensions (en-x-a001, en-x-a002, …), an unauthenticated attacker can generate an unlimited number of unique cache keys by sending requests with novel locale tags, growing the cache until heap memory is exhausted and the JVM crashes. This vulnerability is fixed in 4.10.22.
CVE-2026-44242 1 Micronaut-projects 1 Micronaut-core 2026-05-13 3.7 Low
Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. Prior to 4.10.22, the bundleCache is keyed by (Locale, baseName) where the locale originates from the HTTP Accept-Language header. In applications that explicitly register a ResourceBundleMessageSource bean and serve HTML error responses, an unauthenticated attacker can exhaust heap memory by sending requests with large numbers of unique Accept-Language values, each causing a new entry in the unbounded bundleCache. This vulnerability is fixed in 4.10.22.
CVE-2026-43653 1 Apple 5 Ios And Ipados, Ipados, Iphone Os and 2 more 2026-05-13 6.2 Medium
