CVE-2026-58470 is fixed in 5 products on 1 platform, first by wget 1.25.0-2ubuntu4.2, released July 7, 2026. It is not reported as exploited. Patch Radar priority: Routine.
GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the parse_content_range() function within src/http.c that allows server-controlled values to cause signed integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigger undefined behavior and download desynchronization in the affected client.
