nginx: NGINX: Heap buffer over-read allows memory modification or denial of service

A vulnerability in NGINX's ngxhttpssimodule allows an unauthenticated MITM attacker to trigger a heap buffer over-read by manipulating upstream server responses. This requires SSI, proxypass, and proxybuffering off to be configured, and can result in memory modification or a Denial of Service DoS...

Astra Linux – Vulnerability in Ruby 2.5, JRuby

A issue was discovered in Ruby between versions 2.6.7, 2.7.x up to 2.7.3, and 3.x up to 3.0.1. The Net::IMAP library does not raise an exception when the StartTLS command fails with an unknown response. This may allow man-in-the-middle attackers to bypass TLS protections by leveraging the network...

Improper Validation of Certificate with Host Mismatch

Overview io.netty:netty-handler is a library that provides an asynchronous event-driven network application framework and tools for rapid development of maintainable high performance and high scalability protocol servers and clients. In other words, Netty is a NIO client server framework which...

CVE-2026-63310

NLTK (Natural Language Toolkit) versions before 3.9.3 contain a missing post-download integrity verification flaw in the downloader module . After downloading packages, the module fails to validate file integrity before extraction. An attacker positioned for a man-in-the-middle attack or performi...

CVE-2026-62243

Netty io.netty:netty-handler versions from 4.2.0.Final through 4.2.16.Final and versions through 4.1.136.Final disable TLS hostname verification on the SslProvider.OPENSSL client path when a plain non-extended X509TrustManager is used and Unsafe-based trust-manager wrapping is unavailable Java 25...

CVE-2026-62243 Netty 4.2.0 through 4.2.16 TLS Hostname Verification Bypass

Netty io.netty:netty-handler versions from 4.2.0.Final through 4.2.16.Final and versions through 4.1.136.Final disable TLS hostname verification on the SslProvider.OPENSSL client path when a plain non-extended X509TrustManager is used and Unsafe-based trust-manager wrapping is unavailable Java 25...

CVE-2026-53583

In libgit2 before 1.8.6 and 1.9.5, verify_server_cert in src/libgit2/streams/openssl.c uses an inverted !!memcmp in the GEN_IPADD branch, so OpenSSL builds accept mismatched IP SubjectAltName certificates and reject matching ones, enabling a network attacker to intercept IP-literal HTTPS connecti...

CVE-2026-53583 libgit2: Inverted IP SubjectAltName Comparison in OpenSSL Backend

libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, verifyservercert in src/libgit2/streams/openssl.c uses an inverted !!memcmp result in the GENIPADD...

CVE-2026-66787

In Red Hat Advanced Cluster Management for Kubernetes, the lighthouse component fails to validate IP addresses in EndpointSlice objects. A compromised spoke cluster can publish attacker-controlled IPs, causing other clusters' lighthouse DNS to resolve legitimate cross-cluster service names to mal...

CVE-2026-66787 Lighthouse: lighthouse: cross-cluster dns spoofing via unvalidated endpointslice and serviceimport ips

A flaw was found in the lighthouse component of Red Hat Advanced Cluster Management for Kubernetes. This vulnerability stems from insufficient validation of advertised IP addresses within EndpointSlice objects. A compromised spoke cluster can exploit this by creating EndpointSlices with...

CVE-2026-54481

A flaw was found in Gitea. The internal API HTTP client is configured to skip Transport Layer Security TLS certificate verification, which is an insecure practice. A remote attacker on the same network segment could exploit this vulnerability to perform man-in-the-middle MITM attacks. This allows...
