{"id":"CVE-2026-28677","summary":"OpenSift: Insufficient URL destination restrictions in ingest flow could enable SSRF-style internal access","details":"OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. Prior to version 1.6.3-alpha, the URL ingest pipeline accepted user-controlled remote URLs with incomplete destination restrictions. Although private/local host checks existed, missing restrictions for credentialed URLs, non-standard ports, and cross-host redirects left SSRF-class abuse paths in non-localhost deployments. This issue has been patched in version 1.6.3-alpha.","aliases":["GHSA-5jfc-p787-2mf9"],"modified":"2026-04-10T05:41:22.038240Z","published":"2026-03-06T04:23:23.695Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28677.json","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://github.com/OpenSift/OpenSift/releases/tag/v1.6.3-alpha"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28677.json"},{"type":"ADVISORY","url":"https://github.com/OpenSift/OpenSift/security/advisories/GHSA-5jfc-p787-2mf9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28677"},{"type":"FIX","url":"https://github.com/OpenSift/OpenSift/commit/1126e0a503876056a68a434e19f64158a5a4840b"},{"type":"FIX","url":"https://github.com/OpenSift/OpenSift/commit/de99b9c"},{"type":"FIX","url":"https://github.com/OpenSift/OpenSift/pull/67"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensift/opensift","events":[{"introduced":"0"},{"fixed":"1126e0a503876056a68a434e19f64158a5a4840b"}]},{"type":"GIT","repo":"https://github.com/opensift/opensift","events":[{"introduced":"0"},{"fixed":"de99b9c"}]},{"type":"GIT","repo":"https://github.com/opensift/opensift","events":[{"introduced":"0"},{"fixed":"316e4621ab65b52c283d0d6350280df46408a096"}]}],"versions":["v1.0.0-alpha","v1.0.1-alpha","v1.1.0-alpha","v1.1.1-alpha","v1.1.2-alpha","v1.1.3-alpha","v1.3.1-alpha","v1.4.0-alpha","v1.5.0-alpha","v1.6.2-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28677.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L"}]}
