CVE-2025-54387: IPX is Vulnerable to Path Traversal via Prefix Matching Bypass

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.7% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2025-08-05 · updated 2026-06-17

Description

IPX is an image optimizer powered by sharp and svgo. In versions 1.3.1 and below, 2.0.0-0 through 2.1.0, and 3.0.0 through 3.1.0, the approach used to check whether a path is within allowed directories is vulnerable to path prefix bypass when the allowed directories do not end with a path separator. This occurs because the check relies on a raw string prefix comparison. This is fixed in versions 1.3.2, 2.1.1 and 3.1.1.

Affected products

• unjs ipx: before 1.3.2; from 2.0.0 before 2.1.1; from 3.0.0 before 3.1.1 — fixed in 1.3.2, 2.1.1, 3.1.1

How to fix

Upgrade to a fixed version: unjs ipx 1.3.2, 2.1.1, 3.1.1. Check the vendor advisory for mitigations.
