{"id":"CVE-2023-27494","state":"PUBLISHED","title":"Streamlit Cross-site Scripting vulnerability","description":"Streamlit, software for turning data scripts into web applications, had a cross-site scripting (XSS) vulnerability in versions 0.63.0 through 0.80.0. 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.","publishedAt":"2023-03-16T20:29:17.975Z","updatedAt":"2025-02-25T14:54:44.086Z","severity":{"score":5.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["streamlit streamlit"],"affected":[{"vendor":"streamlit","product":"streamlit","versions":[{"version":">= 0.63.0, < 0.81.0","status":"affected"}]}],"references":["https://github.com/streamlit/streamlit/security/advisories/GHSA-9c6g-qpgj-rvxw","https://github.com/streamlit/streamlit/commit/afcf880c60e5d7538936cc2d9721b9e1bc02b075"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:05:52.290Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/27xxx/CVE-2023-27494.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-27494","state":"PUBLISHED","datePublished":"2023-03-16T20:29:17.975Z","dateUpdated":"2025-02-25T14:54:44.086Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-03-01T19:03:56.635Z"},"containers":{"cna":{"title":"Streamlit Cross-site Scripting vulnerability","descriptions":[{"lang":"en","value":"Streamlit, software for turning data scripts into web applications, had a cross-site scripting (XSS) vulnerability in versions 0.63.0 through 0.80.0.
