CVE-2025-69195: GNU WGET2

High severity, CVSS 8.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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)
