CVE-2026-29796 IGL-Technologies eParking.fi Missing Authentication for Critical Function

WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then...

CVE-2026-29796 IGL-Technologies eParking.fi Missing Authentication for Critical Function

CVE-2026-29796

CVE-2026-29796 involves WebSocket endpoints in OCPP-based charging-station/back-end deployments (notably IGL-Technologies eParking.fi) that lack authentication. An unauthenticated attacker can connect to the WebSocket, impersonate a charging station, and issue/receive OCPP commands as a legitimat...

CVE-2026-27649

The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent...

CVE-2026-27649 CTEK Chargeportal Insufficient Session Expiration

The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent...

CVE-2026-31904

CVE-2026-31904 concerns the WebSocket API used by CTEK Chargeportal. The issue arises from a lack of rate limiting on authentication requests within the WebSocket interface, which could allow an attacker to perform denial-of-service attacks that suppress or mis-route charger telemetry, or execute...

CVE-2026-31904

The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain...

CVE-2026-31904 CTEK Chargeportal Improper Restriction of Excessive Authentication Attempts

The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain...

An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then...

CVE-2026-25192

CVE-2026-25192 affects WebSocket endpoints (OCPP) used for charging stations, where no authentication is required. The Red Hat, EUVD, and NVD entries describe an unauthenticated attacker connecting to the OCPP WebSocket endpoint with a known or discovered charging station identifier and issuing o...

CVE-2026-33203 SiYuan has an Unauthenticated WebSocket DoS via Auth Keepalive Bypass

SiYuan is a personal knowledge management system. Prior to version 3.6.2, the SiYuan kernel WebSocket server accepts unauthenticated connections when a specific "auth keepalive" query parameter is present. After connection, incoming messages are parsed using unchecked type assertions on...

CVE-2026-33203

CVE-2026-33203 affects SiYuan prior to 3.6.2. The SiYuan kernel WebSocket server accepts unauthenticated connections when an explicit auth keepalive parameter is present. After connection, messages are parsed with unchecked type assertions on attacker-controlled JSON, allowing a remote attacker t...

CVE-2026-23538

A vulnerability was identified in the Feast Feature Server's /ws/chat endpoint that allows remote attackers to establish persistent WebSocket connections without any authentication. By opening a large number of simultaneous connections, an attacker can exhaust server resources—such as memory, CPU...

GHSA-6QH5-M6G3-XHQ6 Parse Server LiveQuery subscription query depth bypass

Impact Parse Server's LiveQuery component does not enforce the requestComplexity.queryDepth configuration setting when processing WebSocket subscription requests. An attacker can send a subscription with deeply nested logical operators, causing excessive recursion and CPU consumption that degrade...

Uncontrolled Recursion

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Uncontrolled Recursion via the requestComplexity.queryDepth configuration setting when processing WebSocket subscription...
