Severity9.1 Critical CVSS 3.1
WeaknessServer-side request forgery (CWE-918)
Published13 Oct 2026
Updated20 Oct 2026

Published 32 days ago. NVD often adds the list of affected products days or weeks after a CVE is published, and the other sources we check lag too. The scope and status here may change.

Description

Server-Side Request Forgery (SSRF) protection in the UrlImageConverter component of Apache Fesod (Incubating) fesod-sheet 2.0.2-incubating can be bypassed through DNS rebinding. When an application accepts an attacker-controlled image URL for spreadsheet writing, the converter checks the hostname's resolved IP addresses and then opens a separate connection that can resolve the hostname again. An attacker who controls DNS responses for the URL hostname may cause the connection to reach a restricted address after validation. CVE-2026-49328 covers SSRF in releases before 2.0.2-incubating; this issue is a DNS rebinding bypass of the protection in 2.0.2-incubating. Apache Fesod (Incubating) 2.1.0-incubating addresses the reported default-fetch scenario by disabling remote URL image fetching by default and requiring an explicit exact-host allowlist when the feature is enabled. Users should upgrade to 2.1.0-incubating. Applications enabling remote URL image fetching should allowlist only hostnames whose DNS and HTTP services are trusted.

Decided by Exploit code for this candidate, published in a reviewed catalogue or a GitHub repository with 5 or more stars, or in use per CISA or VulnCheck; not only a CISA verdict, a forecast, or nothing at all
Finding This CVE is not listed in CISA KEV or VulnCheck KEV, CISA Vulnrichment records no active exploitation, no reviewed exploit catalogue carries an entry for it, and no GitHub PoC repository for it has 5 or more stars. Nobody has published exploit code worth tracing, so it is not a candidate for a rule ahead of the ones where somebody has; an upstream fix path does exist, so the remediation half of the candidacy still holds. This is a statement about what has been published, not about whether the defect is reachable or serious.
