io.netty/netty-codec-haproxy: Netty codec-haproxy: Denial of Service via crafted PROXY protocol v2 message

A flaw was found in Netty's codec-haproxy module. A remote attacker could exploit a vulnerability in the HAProxyMessageDecoder by sending a specially crafted PROXY protocol v2 message. This leads to unbounded buffer accumulation, causing a denial of service DoS due to memory exhaustion...

keycloak-services: keycloak-services: LDAP entry-DN user search bypasses configured users DN boundary

A flaw was found in the LDAP storage provider of Keycloak, which is used to federate user identities from external directories. The issue occurs when a delegated administrator performs a search using a specific LDAP entry Distinguished Name DN. Due to missing validation, the system allows lookups...

CVE-2026-70606

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 40.10.6, 41.9.1, 42.5.1, and 43.0.0, when a custom protocol handler returned a ProtocolResponse with a url and no session, Electron made the upstream request through defaultSession...

CVE-2026-14587

Neo4j Bolt handshake decoder mishandles an overlong capability bitmask: when an unauthenticated client sends a protocol version followed by 32 continuation bytes, the decoder resets its reader index and waits for more data instead of rejecting the message and closing the channel, leaving the conn...

CVE-2026-14587 Unathenticated connection can hold Bolt channel open

Neo4j's Bolt modern handshake decoder treats an overlong capability bit mask the same way it treats a truncated bit mask. When an unauthenticated client sends a selected protocol version followed by 32 continuation bytes in the capability mask, the decoder resets the reader index and waits for mo...
