CVE-2026-46561

pyLoad: SSRF via HTTP Redirect Bypass in parse_urls API

Published May 28, 2026 CVSS 3.1 · 5 Medium EPSS < 1% KEV · Not listed
Description
pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, the PREREQFUNCTION-based private IP check was not applied to HTTPRequest (used by the parse_urls API). An authenticated attacker can supply a URL pointing to an attacker-controlled server that responds with a 302 redirect to an internal/private IP address, bypassing the is_global_host() check on the initial URL. This vulnerability is fixed in 0.5.0b3.dev100.
