• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-01-09 · updated 2026-06-17

Description

A flaw was found in GNU Wget2. This vulnerability, a stack-based buffer overflow, occurs in the filename sanitization logic when processing attacker-controlled URL paths, particularly when filename restriction options are active. A remote attacker can exploit this by providing a specially crafted URL, which, upon user interaction with wget2, can lead to memory corruption. This can cause the application to crash and potentially allow for further malicious activities.

Affected products

• gnu wget2: from 2.1.0 before 2.2.1 — fixed in 2.2.1

How to fix

Upgrade to a fixed version: gnu wget2 2.2.1. Check the vendor advisory for mitigations.
