Threats
Impact
Important
A flaw was found in Apache Thrift. A remote, unauthenticated attacker could cause a Denial of Service (DoS) by sending specially crafted network traffic to an affected application. Due to an integer underflow in the 32-bit C++ THeaderTransport component, processing this malformed data triggers an out-of-bounds memory write, leading to an application crash.

CVE-2026-82458
Threats
Impact
Important
A flaw was found in Apache Thrift's Perl bindings. Due to insecure default settings and improper certificate validation, client connections fail to verify the authenticity of remote server certificates. An unauthenticated attacker positioned on the network could exploit this vulnerability to conduct a man-in-the-middle (MitM) attack, allowing them to eavesdrop on or alter transmitted data and resulting in information disclosure.

Threats
Impact
Important
A flaw was found in Apache Thrift. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending specially crafted requests to applications utilizing affected language bindings. Flawed input parameter processing and resource allocation can trigger application crashes or excessive resource consumption, rendering the service unavailable.

Impact
Important
A flaw was found in Apache Thrift. An incorrect bitwise integer shift in the C++ THeaderProtocol implementation can cause a stack-based buffer overflow. A remote, unauthenticated attacker could exploit this vulnerability by sending specially crafted input, resulting in a Denial of Service (DoS) caused by an application crash.

Threats
Impact
Important
A flaw was found in Apache Thrift's THeaderTransport component. Due to a failure to release allocated memory and system resources after their operational lifetime, a remote attacker can exploit this vulnerability by sending network traffic that repeatedly consumes resources. This issue can cause system memory exhaustion, leading to a Denial of Service (DoS).

Important
A flaw was found in Apache Thrift's Dart bindings. An unauthenticated remote attacker can exploit this vulnerability by sending input containing inconsistent length parameters, triggering excessive memory allocation. This can lead to system memory exhaustion, resulting in a Denial of Service (DoS) condition.
