protobuf-python has a potential Denial of Service issue

SummaryAny project that uses Protobuf pure-Python backend to parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUP tags can be corrupted by exceeding the Python recursion limit.Reporter: Alexis Challande, Trail of Bits...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion during the JSON conversion. An attacker can exhaust the call stack and cause the application to crash by supplying crafted protobuf binary data containing deeply nested Any values that are expanded during...

protobuf.js: Denial of service through unbounded protobuf recursion

Summary protobufjs could recurse without a depth limit while decoding nested protobuf data. This affected both skipping unknown group fields and generated decoding of nested message fields. A crafted protobuf binary payload could cause the JavaScript call stack to be exhausted during decoding...

Uncontrolled Recursion

Overview protobufjs-cli is a Translates between file formats and generates static code as well as TypeScript definitions. Affected versions of this package are vulnerable to Uncontrolled Recursion through unbounded recursion when decoding nested message fields. An attacker can exhaust the call...

Improper Handling of Unicode Encoding

Overview Affected versions of this package are vulnerable to Improper Handling of Unicode Encoding in the decoding of overlong UTF-8 strings. An attacker can bypass application-level byte filtering or validation by sending malicious sequences that decode to canonical characters. This is only...

PT-2026-40535

Name of the Vulnerable Software and Affected Versions protobufjs versions prior to 7.5.6 protobufjs versions prior to 8.0.2 Description An issue exists in the decoding process of nested protobuf data where the library can recurse without a depth limit. This affects the generated decoding of neste...

The vulnerability of the Protobuf data serialization protocol, related to uncontrolled recursion, allows attackers to cause service failures.

The vulnerability of the Protobuf data serialization protocol is related to uncontrolled recursion. Exploiting this vulnerability could allow a malicious actor to cause service failures remotely...

📄 Meshtastic Buffer Overflow

A fault in the handling of mesh packets containing invalid protobuf data can result in an attacker-controlled buffer overflow, allowing an attacker to hijack execution flow, potentially resulting in remote code execution. This attack does not require authentication or user interaction, as long as...
