Users of hosted Streamlit app(s) were vulnerable to a reflected XSS vulnerability. An attacker could craft a malicious URL with Javascript payloads to a Streamlit app. The attacker could then trick the user into visiting the malicious URL and, if successful, the server would render the malicious javascript payload as-is, leading to XSS. Version 0.81.0 contains a patch for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/streamlit/streamlit/commit/afcf880c60e5d7538936cc2d9721b9e1bc02b075","https://github.com/streamlit/streamlit/security/advisories/GHSA-9c6g-qpgj-rvxw","https://github.com/streamlit/streamlit/commit/afcf880c60e5d7538936cc2d9721b9e1bc02b075","https://github.com/streamlit/streamlit/security/advisories/GHSA-9c6g-qpgj-rvxw"],"products":["snowflake:streamlit"],"source":"nvd","synced_at":"2026-10-19T21:37:41.955480748+00:00"},"epss":{"cve":"CVE-2023-27494","score":0.0041,"percentile":0.353,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9c6g-qpgj-rvxw","url":"https://osv.dev/vulnerability/GHSA-9c6g-qpgj-rvxw","summary":"Streamlit publishes previously-patched Cross-site Scripting vulnerability","modified":"2024-10-28T14:44:06.146639Z","packages":[{"ecosystem":"PyPI","name":"streamlit","purl":"pkg:pypi/streamlit","ranges":[">=0.63.0 <0.81.0"],"fixed":["0.81.0"]}]},{"id":"PYSEC-2023-50","url":"https://osv.dev/vulnerability/PYSEC-2023-50","summary":"","modified":"2023-11-08T04:12:05.345176Z","packages":[{"ecosystem":"PyPI","name":"streamlit","purl":"pkg:pypi/streamlit","ranges":[">=0.63.0 <0.81.0"],"fixed":["0.81.0"]}]}],"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).
