{"cve":"CVE-2026-33682","nvd":{"published":"2026-03-26T22:16:30.880","modified":"2026-06-17T10:37:55.193","status":"Analyzed","description":"Streamlit is a data oriented application development framework for python. Streamlit Open Source versions prior to 1.54.0 running on Windows hosts have an unauthenticated Server-Side Request Forgery (SSRF) vulnerability. The vulnerability arises from improper validation of attacker-supplied filesystem paths. In certain code paths, including within the `ComponentRequestHandler`, filesystem paths are resolved using `os.path.realpath()` or `Path.resolve()` before sufficient validation occurs. On Windows systems, supplying a malicious UNC path (e.g., `\\\\attacker-controlled-host\\share`) can cause the Streamlit server to initiate outbound SMB connections over port 445. When Windows attempts to authenticate to the remote SMB server, NTLMv2 challenge-response credentials of the Windows user running the Streamlit process may be transmitted. This behavior may allow an attacker to perform NTLM relay attacks against other internal services and/or identify internally reachable SMB hosts via timing analysis. The vulnerability has been fixed in Streamlit Open Source version 1.54.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","score":4.8},"cwes":["CWE-918"],"references":["https://github.com/streamlit/streamlit/commit/23692ca70b2f2ac720c72d1feb4f190c9d6eed76","https://github.com/streamlit/streamlit/releases/tag/1.54.0","https://github.com/streamlit/streamlit/security/advisories/GHSA-7p48-42j8-8846"],"products":["snowflake:streamlit"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33682","score":0.00296,"percentile":0.22288,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7p48-42j8-8846","url":"https://osv.dev/vulnerability/GHSA-7p48-42j8-8846","summary":"Unauthenticated SSRF Vulnerability in Streamlit on Windows (NTLM Credential Exposure)","modified":"2026-07-13T07:26:25.253864212Z","packages":[{"ecosystem":"PyPI","name":"streamlit","purl":"pkg:pypi/streamlit","ranges":["<1.54.0"],"fixed":["1.54.0"]}]},{"id":"PYSEC-2026-2285","url":"https://osv.dev/vulnerability/PYSEC-2026-2285","summary":"","modified":"2026-07-13T07:15:44.770297942Z","packages":[{"ecosystem":"PyPI","name":"streamlit","purl":"pkg:pypi/streamlit","ranges":["<1.54.0"],"fixed":["1.54.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
