{"id":"CVE-2026-53555","summary":"Stored XSS via SVG Upload","details":"SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, an authenticated uploader can submit an image/svg+xml assistant UI logo through PATCH /api/v1/system/assistant/ui, and SQLBot stores the SVG without sanitizing or validating embedded active content. SQLBot later serves the file inline from the same application origin through GET /api/v1/system/assistant/picture/{filename}. When another user loads that generated resource, JavaScript embedded in the SVG executes in the SQLBot web application context, resulting in stored cross-site scripting with access to data and actions available to the victim's session. This issue is fixed in version 1.9.0.","aliases":["GHSA-v23m-5pvq-xcgx"],"modified":"2026-09-20T11:30:45.517043368Z","published":"2026-09-17T21:40:48.271Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53555.json"},"references":[{"type":"WEB","url":"https://github.com/dataease/SQLBot/releases/tag/v1.9.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53555.json"},{"type":"ADVISORY","url":"https://github.com/dataease/SQLBot/security/advisories/GHSA-v23m-5pvq-xcgx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53555"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/commit/835eefcb39b595248ea006f3cfce445d2f49167e"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/pull/1160"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dataease/sqlbot","events":[{"introduced":"0"},{"fixed":"835eefcb39b595248ea006f3cfce445d2f49167e"},{"fixed":"7637ab391d4a3d2c910c8e265033b155d5c8fea9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.9.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.4","v1.1.3","v1.1.2","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53555.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
