Unbounded line buffer in stdio transports leads to memory exhaustion (DoS)

Summary The stdio transports in MCP::Server::Transports::StdioTransport and MCP::Client::Stdio read newline-delimited JSON-RPC frames using IOgets with no limit argument. CRuby's IOgets with no limit reads from the current position until the next separator \n with no upper bound on the returned...

CVE-2026-59712

Leantime's Users::getUser method in the JSON-RPC API lacks proper authorization checks, allowing authenticated users to retrieve full user credential rows including password hashes, TOTP secrets, and session tokens. Attackers can exploit this by calling users.getUser with arbitrary user IDs to...

CVE-2026-59712

According to the connected NVD records, CVE-2026-59712 affects Leantime’s JSON-RPC API via the Users::getUser method. The vulnerability arises from missing authorization checks, enabling authenticated users to call users.getUser with arbitrary user IDs and enumerate accounts. The outcome is expos...

User Impersonation

Overview Affected versions of this package are vulnerable to User Impersonation in certain Thrift RPC query handlers, which do not strictly validate the sessionId parameter. An attacker can read time-series data without authenticating by sending query requests carrying a forged sessionId, which t...

User Impersonation

Overview org.apache.iotdb:iotdb-server is a data management system for time series data, which can provide users specific services, such as, data collection, storage and analysis. Affected versions of this package are vulnerable to User Impersonation in certain Thrift RPC query handlers, which do...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the DataNode internal RPC interface for creating Trigger instances, which builds a file path from the uploaded Trigger JAR name without sufficient validation. An attacker can write arbitrary files with the...

CVE-2026-24014

Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name t...

CVE-2026-24013 Apache IoTDB: Authentication Bypass via Forged SessionID in Thrift RPC

Authentication Bypass by Spoofing vulnerability in Apache IoTDB. Certain Thrift RPC query handlers lack strict validation of the sessionId parameter. An attacker can construct requests with a forged sessionId and, without performing openSession authentication, receive valid query results. This...

CVE-2026-24013

Apache IoTDB versions 1.3.3 through 2.0.7 are vulnerable to an Authentication Bypass by Spoofing vulnerability. The root cause is the lack of strict validation of the sessionId parameter within certain Thrift RPC query handlers . An attacker can construct requests with a forged sessionId to bypas...

CVE-2026-24014

Apache IoTDB versions 1.3.3 through 2.0.7 are vulnerable to a path traversal vulnerability in the DataNode’s internal RPC interface. When creating Trigger instances, the system fails to sufficiently validate the name of the uploaded Trigger JAR when constructing a file path. If the internal DataN...

CVE-2026-24014 Apache IoTDB: Path Traversal in DataNode Internal RPC Trigger JAR Upload Allows Arbitrary File Write

Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name t...

CVE-2026-59712: Authorization Bypass Through User-Controlled Key

Leantime's Users::getUser method in the JSON-RPC API lacks proper authorization checks, allowing authenticated users to retrieve full user credential rows including password hashes, TOTP secrets, and session tokens. Attackers can exploit this by calling users.getUser with arbitrary user IDs to...

CVE-2026-24014: Improper Access Control

Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation.
