CVE-2026-58472

A flaw was found in GNU Wget. A remote attacker can exploit a heap buffer overflow vulnerability in the html_quote_string() function by providing a specially crafted HTML attribute. This can lead to memory corruption and potentially result in arbitrary code execution or a denial of service.

This Moderate impact heap buffer overflow in GNU Wget occurs when processing HTML attributes with extensive entity encoding. Successful exploitation requires user interaction, as a victim must download a specially crafted HTML file, and is further constrained by high attack complexity. This limits the direct risk to Red Hat systems where Wget is typically used for trusted content retrieval.
