{"schema":"threatline.record/2","record":{"id":"CVE-2026-63147","aliases":[],"summary":"Omnispace Agora Project < 26.10.0 Stored XSS via Uploaded File Name","details":"Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious script by uploading a file with HTML/script markup embedded in its filename, which bypasses the paramFilter since uploaded-file names arrive through $_FILES rather than $_GET/$_POST. Attackers can upload a file with a crafted name such as an SVG onload payload to have the unsanitized filename stored and later rendered to other users, resulting in script execution in their browsers.","categories":["Unclassified"],"product":"Agora Project","vendor":"Omnispace","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-63147","source_modified_at":"2026-10-17T00:47:42.793Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Agora Project","vendor":"Omnispace","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"26.10.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-63147","source_modified_at":"2026-10-17T00:47:42.793Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Agora Project","ecosystem":null},"version":"26.10.0","basis":"first unaffected version stated in the CVE record"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00209,"percentile":0.10443,"score_date":"2026-10-23"},"published_at":"2026-10-13T19:59:44.084Z","modified_at":"2026-10-17T00:47:42.793Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-63147","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-17T00:47:42.793Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-63147","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/xech/agora-project/releases/tag/26.10","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.agora-project.net/","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/omnispace-agora-project-stored-xss-via-uploaded-file-name","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-17T00:47:32.888215Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-17T00:47:42.793Z","content_hash":"42b6347ecc8863f3d43668e749ec77b8e18eca2249c99e7a60d76cf32443ebdf"}}
