SurrealDB versions before 3.1.0 fail to apply the SURREAL_WEBSOCKET_MAX_MESSAGE_SIZE limit to anonymous /sql WebSocket connections, allowing attackers to buffer unbounded frames in the per-connection read buffer. Attackers can stream WebSocket frames larger than the configured limit across multiple concurrent connections to consume excessive memory and degrade /sql availability.

The Model Context Protocol has a security warning advising servers to validate the "Origin" header on all incoming connections to prevent DNS rebinding attacks. Prior to the v0.25.0 release, users had no way to validate the origin's host. In v0.25.0, a new "--allowed-hosts" flag was introduced alongside the existing "--allowed-origins" flag, enabling users to specify permitted hosts at server startup. Both flags default to "*", allowing users to implement strict access controls as needed without breaking existing setups. If either flag is set to "*", the server will output a startup warning about potential vulnerabilities. Documentation has also been updated to highlight these security considerations.

Jun 1, 2026Apache Airflow's EmailOperator and the underlying `airflow.utils.email` helpers established SMTP STARTTLS connections without verifying the remote certificate wCVE-2026-49267 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 5.9
Apache Airflow's EmailOperator and the underlying `airflow.utils.email` helpers established SMTP STARTTLS connections without verifying the remote certificate when the deployment used `[email] smtp_starttls=True` without `[email] smtp_ssl`. An attacker positioned between the worker and the configured SMTP server (network MITM — typical hostile-network attack-surface for environments where the SMTP relay sits outside the worker's trust boundary) could present a self-signed certificate, have the worker complete the STARTTLS handshake silently, and capture the SMTP AUTH credentials and message contents the worker forwarded. This CVE covers the **core apache-airflow side** of the same root cause already covered for the SMTP provider by `CVE-2026-41016` (published 2026-04-27, covering `apache-airflow-providers-smtp`). Users who already applied the SMTP-provider fix from CVE-2026-41016 should additionally upgrade `apache-airflow` to 3.2.2 or later to cover the core-side path through `airflow.utils.email`.

A bug in the GET `/api/v2/connections/{connection_id}` REST API endpoint in Apache Airflow allowed an authenticated UI/API user with Connection-read permission to retrieve secrets stored in a Connection's `extra` JSON blob under field names not present in the redaction allowlist (`DEFAULT_SENSITIVE_FIELDS`) — for example, official Slack-provider credential field names were returned in plaintext. Affects deployments that store credentials in Connection `extra` blobs and grant Connection-read access to multiple users. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can store sensitive credential values in a secret-backend rather than inlined into the Connection's `extra` field.

May 26, 2026FastNetMon Community Edition through 1.2.9 does not verify TLS certificates on outbound HTTPS connections.CVE-2026-48697 · Other software · Pavel-odintsov · reported by MITREHigh 7.4
FastNetMon Community Edition through 1.2.9 does not verify TLS certificates on outbound HTTPS connections. The execute_web_request_secure() function in src/fast_library.cpp creates a boost::asio::ssl::context with tls_client mode and calls set_default_verify_paths() to load CA certificates, but never calls set_verify_mode(boost::asio::ssl::verify_peer). Without this call, OpenSSL performs the TLS handshake without validating the server's certificate chain, making all HTTPS connections vulnerable to man-in-the-middle attacks. This function is used for telemetry reporting to community-stats.fastnetmon.com, which sends system information including CPU model, kernel version, traffic statistics, and software configuration. An attacker can intercept and modify this data or redirect it to a malicious server.

HP ENVY 5000 series printers VERBASPP1N003.2237A.00 do not properly manage concurrent TCP connections to port 9100 (JetDirect/RAW printing). An unauthenticated remote attacker on the same network can establish a persistent connection to port 9100 and send keep-alive packets, causing the printer's session threads to remain locked in a waiting state. The firmware lacks connection timeouts and concurrent session limits, resulting in a persistent Denial of Service (DoS) that renders the printer unresponsive to all user commands and print jobs. Physical intervention (manual restart) is required to restore functionality, and the attack can be immediately re-initiated.

In the Linux kernel, the following vulnerability has been resolved: net/rds: No shortcut out of RDS_CONN_ERROR RDS connections carry a state "rds_conn_path::cp_state" and transitions from one state to another and are conditional upon an expected state: "rds_conn_path_transition." There is one exception to this conditionality, which is "RDS_CONN_ERROR" that can be enforced by "rds_conn_path_drop" regardless of what state the condition is currently in. But as soon as a connection enters state "RDS_CONN_ERROR", the connection handling code expects it to go through the shutdown-path. The RDS/TCP multipath changes added a shortcut out of "RDS_CONN_ERROR" straight back to "RDS_CONN_CONNECTING" via "rds_tcp_accept_one_path" (e.g. after "rds_tcp_state_change"). A subsequent "rds_tcp_reset_callbacks" can then transition the state to "RDS_CONN_RESETTING" with a shutdown-worker queued. That'll trip up "rds_conn_init_shutdown", which was never adjusted to handle "RDS_CONN_RESETTING" and subsequently drops the connection with the dreaded "DR_INV_CONN_STATE", which leaves "RDS_SHUTDOWN_WORK_QUEUED" on forever. So we do two things here: a) Don't shortcut "RDS_CONN_ERROR", but take the lo

Apr 16, 2026spdystream is a Go library for multiplexing streams over SPDY connections.CVE-2026-35469 · Other software · moby · reported by GitHubHigh 8.7
spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count in parseHeaderValueBlock, and individual header field sizes — all read as 32-bit integers and used directly as allocation sizes with no bounds checking. Because SPDY header blocks are zlib-compressed, a small on-the-wire payload can decompress into large attacker-controlled values. A remote peer that can send SPDY frames to a service using spdystream can exhaust process memory and cause an out-of-memory crash with a single crafted control frame. This issue has been fixed in version 0.5.1.

Mar 16, 2026Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP.CVE-2026-32314 · Other software · libp2p · reported by GitHubHigh 8.7
Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP. Prior to 0.13.10, the Rust implementation of Yamux can panic when processing a crafted inbound Data frame that sets SYN and uses a body length greater than DEFAULT_CREDIT (e.g. 262145). On the first packet of a new inbound stream, stream state is created and a receiver is queued before oversized-body validation completes. When validation fails, the temporary stream is dropped and cleanup may call remove(...).expect("stream not found"), triggering a panic in the connection state machine. This is remotely reachable over a normal Yamux session and does not require authentication. This vulnerability is fixed in 0.13.10.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't WARN for connections on invalid channels It's not clear (to me) how exactly syzbot managed to hit this, but it seems conceivable that e.g. regulatory changed and has disabled a channel between scanning (channel is checked to be usable by cfg80211_get_ies_channel_number) and connecting on the channel later. With one scenario that isn't covered elsewhere described above, the warning isn't good, replace it with a (more informative) error message.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
