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.","state":0,"publishedAt":"2026-10-13T14:16:02.556+00:00","modifiedAt":"2026-10-20T17:39:28.844+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.fesod:fesod-sheet","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Fesod (Incubating)\",\n                    \"packageURL\": \"pkg:maven/org.apache.fesod/fesod-sheet\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.2-incubating\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.fesod:fesod-sheet\"\n                }"}],"metrics":[],"references":["https://github.com/apache/fesod/pull/1035","https://github.com/apache/fesod/releases/tag/2.1.0-incubating","https://cve.org/CVERecord?id=CVE-2026-49328","https://lists.apache.org/thread/oh706yhm32hmw8vx4kh1948h952pfr83"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107460","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107460","identifiers":["CVE-2026-107460"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
