{"id":"CVE-2026-63498","summary":"Snipe-IT: Stored XSS via Inline XML Rendering in the Uploaded Files API","details":"Snipe-IT is an IT asset/license management system. Prior to 8.7.0, the uploaded-files API endpoint GET /api/v1/{object_type}/{id}/files/{file_id} allows an authenticated user with file-management access to upload XML and XSLT attachments and request them with the inline=true parameter. The app/Http/Controllers/Api/UploadedFilesController.php show() path does not apply the safe-inline allowlist used by the equivalent web controller, so the browser can process an attacker-controlled xml-stylesheet reference and execute JavaScript generated by the stylesheet in the Snipe-IT origin. A victim who is authorized to view the object must open the attachment URL, after which the script can read same-origin data and perform authenticated actions with the victim's privileges. This issue is fixed in version 8.7.0.","aliases":["GHSA-396x-xmvh-p563"],"modified":"2026-09-25T03:48:36.366036094Z","published":"2026-09-24T16:29:57.380Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63498.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63498.json"},{"type":"FIX","url":"https://github.com/grokability/snipe-it/commit/e929b31f0b183c5810bd2b833c1f6f643cbe5284"},{"type":"WEB","url":"https://github.com/grokability/snipe-it/releases/tag/v8.7.0"},{"type":"ADVISORY","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-396x-xmvh-p563"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63498"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/grokability/snipe-it","events":[{"introduced":"0"},{"fixed":"1d05a7ce11e6bf9448c067ac3ffbe5e63882888e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"8.7.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v8.4.0","v8.3.3","v8.3.2","v8.3.1","v8.3.0","v8.2.1","v8.2.0","v8.1.18","v8.1.17","v8.1.16","v8.1.15","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1.0","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v7.1.15","v7.1.14","v7.0.13","v7.0.10","v7.0.9","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.0-pre","v6.3.1","v6.3.0","v6.0.10","v6.0.6","v6.0.5","v6.0.4","v6.0.3","v6.0.1","v6.0.0","v6.0.0-RC-8","v6.0.0-GM","v6.0.0-RC-5","v6.0.0-RC-7","v6.0.0-RC-6","v6.0.0-RC-4","v6.0.0-RC-3","v6.0.0-RC-2","v6.0.0-RC-1","v5.1.8","v5.1.7","5.1.7","v5.1.6","v5.1.4","v5.1.3","v5.1.2","v5.1.1","v5.1.0","v5.0.12","v5.0.11","v5.0.10","v5.0.9","v5.0.8","v5.0.7","v5.0.6","v5.0.5","v5.0.0-beta-7-GM","v5.0.0-beta-6-GM","v5.0.0-beta-5","v5.0.0-beta-4","v5.0.0-beta-3.0","v4.9.4","v4.9.3","v4.9.2","v4.9.1","v4.9.0","v4.8.0","v4.7.8","v4.7.7","v4.7.5","v4.7.4","v4.7.3","v4.7.2","v4.7.0","v4.6.18","v4.6.17","v4.6.16","v4.6.15","v4.6.14","v4.6.13","v4.6.12","v4.6.11","v4.6.10","v4.6.9","v4.6.8","v4.6.7","v4.6.6","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.0","v4.4.1","v4.4.0","v4.3.0","v4.2.0","v4.1.14","v4.1.13","v4.1.12","v4.1.11","v4.1.10","v4.1.9","v4.1.8","v4.1.7","v4.1.6","v4.1.5","v4.1.4","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.15","v4.0.14","v4.0.13","v4.0.12","v4.0.11","v4.0.10","v4.0.9","v4.0.8","v4.0.7","v4.0.6","v4.0.5","v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0","v3.6.6","v3.6.5","v4.0-alpha-2","v3.6.4","v3.6.3","v3.6.2","v3.6.1","v3.6.0","v3.5.2","v3.5.1","v3.5.0","v3.5.0-beta2","v3.5.0-beta","v3.4.0-beta","v3.4.0-alpha","v3.3.0-beta","3.2.0","v3.1.0","v3.0","v3.0-beta.3","v3.0-beta.1","v3.0.0-beta","v3.0-alpha2","v3.0-alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63498.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N"}]}
