CVE-2024-45720: Apache Subversion: Command line argument injection on Windows platforms

• Severity: high (CVSS 7.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-10-09 · updated 2026-06-17

Description

On Windows platforms, a "best fit" character encoding conversion of command line arguments to Subversion's executables (e.g., svn.exe, etc.) may lead to unexpected command line argument interpretation, including argument injection and execution of other programs, if a specially crafted command line argument string is processed. All versions of Subversion up to and including Subversion 1.14.3 are affected on Windows platforms only. Users are recommended to upgrade to version Subversion 1.14.4, which fixes this issue. Subversion is not affected on UNIX-like platforms.

Affected products

• Apache Software Foundation Apache Subversion: before 1.14.4 — fixed in 1.14.4

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Subversion 1.14.4. Check the vendor advisory for mitigations.
