Prior to 1.11.8 and 2.0.0rc3, Suppressed Command notification popups use PNotify rendering for printer-controlled payload.command and payload.message values in src/octoprint/static/js/app/viewmodels/terminal.js without HTML escaping. An attacker who convinces a victim to print a crafted file can inject HTML and JavaScript into the notification, disrupt prints, read information available to the victim including sensitive settings when permitted, or perform actions in the victim's OctoPrint session. This issue is fixed in versions 1.11.8 and 2.0.0rc3.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:L/SC:L/SI:L/SA:N","score":4.6},"cvss_v3":null,"cwes":["CWE-80"],"references":["https://github.com/OctoPrint/OctoPrint/commit/42e0f9863935e136f04ed3c560cb96483a580d1b","https://github.com/OctoPrint/OctoPrint/commit/6e3db9096f8a94f7c2249be24b6d03a7d9c12bc7","https://github.com/OctoPrint/OctoPrint/releases/tag/1.11.8","https://github.com/OctoPrint/OctoPrint/releases/tag/2.0.0rc3","https://github.com/OctoPrint/OctoPrint/security/advisories/GHSA-p6qx-ghxm-389h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-35163","score":0.00199,"percentile":0.09661,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p6qx-ghxm-389h","url":"https://osv.dev/vulnerability/GHSA-p6qx-ghxm-389h","summary":"OctoPrint has XSS in its Suppressed Command Notifications","modified":"2026-08-21T18:30:08.073169678Z","packages":[{"ecosystem":"PyPI","name":"octoprint","purl":"pkg:pypi/octoprint","ranges":["<1.11.8"],"fixed":["1.11.8"]},{"ecosystem":"PyPI","name":"octoprint","purl":"pkg:pypi/octoprint","ranges":[">=2.0.0rc1 <2.0.0rc3"],"fixed":["2.0.0rc3"]}]},{"id":"PYSEC-2026-2688","url":"https://osv.dev/vulnerability/PYSEC-2026-2688","summary":"OctoPrint has XSS in its Suppressed Command Notifications","modified":"2026-07-13T16:32:54.587962771Z","packages":[{"ecosystem":"PyPI","name":"octoprint","purl":"pkg:pypi/octoprint","ranges":["<1.11.8",">=2.0.0rc1 <2.0.0rc3"],"fixed":["1.11.8","2.0.0rc3"]}]}],"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).
