{"schema":"threatline.record/2","record":{"id":"CVE-2026-107460","aliases":[],"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.","categories":["Unclassified"],"product":"Apache Fesod (Incubating)","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107460","source_modified_at":"2026-10-20T17:39:28.844Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Apache Fesod (Incubating)","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"2.0.2-incubating","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":9.1,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00407,"percentile":0.33851,"score_date":"2026-10-23"},"published_at":"2026-10-13T14:16:02.556Z","modified_at":"2026-10-20T17:39:28.844Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107460","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T17:39:28.844Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107460","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/apache/fesod/pull/1035","tags":["patch"]},{"source":"CVE List","url":"https://github.com/apache/fesod/releases/tag/2.1.0-incubating","tags":["release-notes"]},{"source":"CVE List","url":"https://cve.org/CVERecord?id=CVE-2026-49328","tags":["related"]},{"source":"CVE List","url":"https://lists.apache.org/thread/oh706yhm32hmw8vx4kh1948h952pfr83","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-20T17:39:18.695927Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T17:39:28.844Z","content_hash":"26802dd3bc63c7dbe4db37da1df67a787b43e8850dcf332db3082f54a3707470"}}
