CVE-2026-96292 · Severity: info · Published 2026-10-02

Apache Thrift is a framework for building remote procedure call services. The Lua language bindings contain an inefficient regular expression that could allow an attacker to cause excessive CPU consumption and service delays by crafting malicious input.

Technologies: [Apache Thrift](https://junglewise.ai/threats/technologies/thrift). Vendors: [Apache](https://junglewise.ai/threats/vendors/apache).

## Quick answers

**Is CVE-2026-96292 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-96292 being exploited in the wild.

**How severe is CVE-2026-96292?** Informational severity, published 2 October 2026.

**Which products and versions are affected?** Apache Thrift before 0.25.0.

**Is there a fix for CVE-2026-96292?** Yes: fixed in 0.25.0. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-96292 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-96292?** Check whether you run Apache Thrift at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in 0.25.0

## Technical details

The vulnerability is an inefficient algorithmic complexity issue in the Lua bindings of Apache Thrift, involving a regular expression that exhibits poor performance characteristics. An attacker can exploit this by sending specially crafted input that triggers catastrophic backtracking or other regex performance degradation. This can lead to denial of service through CPU exhaustion on systems processing the malicious input.

## Affected products

- Apache Thrift before 0.25.0
