The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.0, com.rabbitmq.client.ConnectionFactory.useSslProtocol and ConnectionFactory.useSslProtocolString configure com.rabbitmq.client.TrustEverythingTrustManager and...

Amazon Linux 2 : pcp, --advisory ALAS2-2026-3857 (ALAS-2026-3857)

The version of pcp installed on the remote host is prior to 4.3.2-12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3857 advisory. A flaw in the PCP linuxsockets module exposes an unsecured internal connection.An attacker with initial code execution can...

Amazon Linux 2023 : gnome-remote-desktop (ALAS2023-2026-2068)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-2068 advisory. A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. When the daemon is running in system mode with RDP enabled, the incoming connection handler bypasses the connection...

DEBIAN-CVE-2026-65976

Deskflow is a keyboard and mouse sharing app. From 1.17.0 until continuous build 1.26.0.300, a connected peer can send repeated DCLP DataChunk messages to ClipboardChunk::assemble in src/lib/deskflow/ClipboardChunk.cpp, causing the server path in src/lib/server/ClientProxy16.cpp or client path in...

CVE-2026-72020

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a new connection is created from a malformed synchronization message, certain TCP sequence number fields may not be properly initialized. This can lead to forwarded packets containing stale data in their TCP sequence an...

CVE-2026-72247

A flaw was found in the Linux kernel's netfilter nfconncount component. An incorrect comparison of conntrack zones in the connection counting logic can cause different zones to be treated as equal. This miscalculation in connection deduplication may lead to connection limits not being properly...

CVE-2026-74802

SiYuan versions before 3.7.4 contain a cross-site WebSocket hijacking vulnerability in the admin-only /ws/network/proxy endpoint that explicitly disables origin validation by setting CheckOrigin to unconditionally return true. Attackers can craft malicious webpages that establish WebSocket...

curl: curl: Authentication bypass due to incorrect connection reuse with Negotiate authentication

A flaw was found in curl. When an application uses libcurl to make multiple Negotiate-authenticated HTTP or HTTPS requests to the same server with different credentials, libcurl may incorrectly reuse an existing connection. This logical error can cause a subsequent request to be sent using the...

curl: curl: Insecure connection establishment due to TLS configuration mismatch

A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...

BIT-NODE-MIN-2026-56850

A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS mTLS client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js 26.x, 24.x, and 22.x...

BIT-NODE-2026-56850

A flaw in Node.js HTTPS Agent connection reuse can cause PFX object-array key collisions, allowing mutual TLS mTLS client identities to be reused across requests configured with different client certificates. This vulnerability affects Node.js 26.x, 24.x, and 22.x...

BIT-AIRFLOW-2026-68076 Apache Airflow: Connections test API: team-scope guard bypass resolves another team's environment Connection

Apache Airflow's environment-variable secrets backend resolved a team-scoped Connection or Variable from the wrong team's scope. The guard meant to prevent this only ran when no team scope was supplied, and its pattern could not match a team name containing an underscore, which team names are...

BIT-CONSUL-2026-15972 Unauthenticated denial of service via unbounded external gRPC connection acceptance

Consul Community Edition and Consul Enterprise 1.13.0 through 2.0.2 are vulnerable to an unauthenticated denial of service through unbounded connection acceptance on the external gRPC listeners. A remote attacker may exhaust agent file descriptors, goroutines, and memory by opening many incomplet...

curl: curl: Authentication bypass due to incorrect connection reuse with Negotiate authentication

A flaw was found in curl. When an application uses libcurl to make multiple Negotiate-authenticated HTTP or HTTPS requests to the same server with different credentials, libcurl may incorrectly reuse an existing connection. This logical error can cause a subsequent request to be sent using the...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

curl: libcurl: Improper certificate validation due to cached TLS settings reuse

A flaw was found in libcurl. When handling secure connections TLS and reusing connection settings, libcurl could incorrectly apply a cached security setting related to certificate chain validation. This could allow libcurl to accept a server's security certificate that it should have otherwise...

curl: curl: Insecure connection establishment due to TLS configuration mismatch

A flaw was found in curl. When a new data transfer attempts to upgrade its connection using STARTTLS, it may incorrectly reuse an existing live connection. This reuse can occur even if the Transport Layer Security TLS configuration of the new transfer does not match the existing connection,...
