Tree Studio 2.17 Denial of Service via Malformed Input

Published Mar 23, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed

Description

Tree Studio 2.17 contains a denial of service vulnerability that allows local attackers to crash the application by providing malformed input through the keyboard interface. Attackers can trigger the vulnerability by entering arbitrary characters during application runtime, causing the application to become unresponsive or terminate abnormally.

Analysis

Technical impact

Tree Studio 2.17 contains a denial‑of‑service flaw that enables a local user to crash the program by typing arbitrary characters into the keyboard interface while the application is running. The malformed input causes the software to become unresponsive or terminate abnormally, disrupting normal workflow. This weakness is classified as improper input validation, identified by CWE‑168.

Affected Systems

The vulnerability affects Pixarra Tree Studio version 2.17 on any operating system where the application is installed and executed. No other versions are listed as vulnerable.

Risk and Exploitability

With a CVSS score of 6.9 the severity is moderate, and the EPSS score of less than 1% suggests a low likelihood of exploitation in the wild. The flaw is not included in the CISA KEV catalog, indicating no known widespread use. Because the attack requires local access and only the keyboard input interface to inject malformed data, a malicious user can temporarily crash the software, potentially leading to unsaved work loss or productivity disruption.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
