{"id":"CVE-2026-107460","summary":"Apache Fesod (Incubating): UrlImageConverter SSRF protection bypass via DNS rebinding","details":"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.","modified":"2026-10-15T02:47:19.435323294Z","published":"2026-10-13T14:16:02.556Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107460.json"},"references":[{"type":"WEB","url":"https://cve.org/CVERecord?id=CVE-2026-49328"},{"type":"WEB","url":"https://repo.maven.apache.org/maven2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107460.json"},{"type":"ADVISORY","url":"https://github.com/apache/fesod/releases/tag/2.1.0-incubating"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/oh706yhm32hmw8vx4kh1948h952pfr83"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107460"},{"type":"FIX","url":"https://github.com/apache/fesod/pull/1035"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/fesod","events":[{"introduced":"0"},{"fixed":"ea6687ff9da3d3389c51a39852d84f3a209708c4"},{"fixed":"5a9a16b9e35060e9d80eede2d1a1dea63ebf9f3e"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.0.2-incubating"}]}}],"versions":["2.0.2-incubating","2.1.0-incubating-rc7","2.1.0-incubating-rc6","2.1.0-incubating-rc5","2.0.1-incubating","1.3.0","1.2.3","1.2.2","1.2.1","1.2.0","1.1.0","1.0.0","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107460.json"}}],"schema_version":"1.9.0"}
