CVE-2026-49328Network attack vector

Restricted-resource access via unchecked image URLs

Published Jun 1, 2026 · Updated Jun 1, 2026

SSRF in Apache Fesod fesod-sheet before 2.0.2-incubating allows remote attackers to request restricted resources through image URLs. UrlImageConverter fetches a supplied URL without restricting schemes, private-network destinations, or redirects. Exploitation requires an embedding application to pass attacker-controlled image URLs to the converter; the bounded impact is access to resources reachable from that host.
