{"id":"CVE-2026-111936","summary":"Sigma File Manager through 2.2.0 SSRF via Extension Download Commands","details":"Sigma File Manager through 2.2.0 contains a server-side request forgery vulnerability because validate_remote_url() in security.rs never checks resolved IP addresses for extension download commands. A malicious extension or catalog entry can use hostnames resolving to loopback, private, or cloud metadata addresses to read internal responses via files written to the extension directory.","modified":"2026-10-21T02:55:50.322057538Z","published":"2026-10-19T13:55:10.311Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111936.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111936.json"},{"type":"PACKAGE","url":"https://github.com/aleksey-hoffman/sigma-file-manager"},{"type":"ARTICLE","url":"https://github.com/aleksey-hoffman/sigma-file-manager/blob/v2.2.0/src-tauri/src/extensions/filesystem.rs"},{"type":"ARTICLE","url":"https://github.com/aleksey-hoffman/sigma-file-manager/blob/v2.2.0/src-tauri/src/extensions/security.rs"},{"type":"FIX","url":"https://github.com/aleksey-hoffman/sigma-file-manager/commit/45cedf892f800c6b140b0e3cd6e55fdbcf2cf479"},{"type":"REPORT","url":"https://github.com/aleksey-hoffman/sigma-file-manager/issues/552"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111936"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/sigma-file-manager-through-2.2.0-ssrf-via-extension-download-commands"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/aleksey-hoffman/sigma-file-manager","events":[{"introduced":"0"},{"last_affected":"e23f6c5c2524a8d5f4919036cf4d097ce63754e8"},{"fixed":"45cedf892f800c6b140b0e3cd6e55fdbcf2cf479"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"0"},{"last_affected":"2.2.0"}]},{"range":[{"fixed":"45cedf892f800c6b140b0e3cd6e55fdbcf2cf479"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.2.0","v2.1.0","v2.0.0-beta.3","api-v1.3.0","v2.0.0-beta.2","v2.0.0-beta.1","v2.0.0-alpha.6","v2.0.0-alpha.5","v2.0.0-alpha.4","v2.0.0-alpha.3","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111936.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
