{"apiVersion":"1.0","identifier":"CVE-2026-35163","description":"OctoPrint provides a web interface for controlling consumer 3D printers. 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.","publishedAt":"2026-08-21T19:17:01","lastModifiedAt":"2026-08-21T20:16:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35163","cvssScore":4.6,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00139,"riskScore":0.47,"affectedProduct":"OctoPrint","affectedVersions":"<1.11.8, <2.0.0rc3","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-35163","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-35163","en":"https://www.redsauce.net/en/cves/CVE-2026-35163","fr":"https://www.redsauce.net/fr/cves/CVE-2026-35163","pt":"https://www.redsauce.net/pt/cves/CVE-2026-35163","de":"https://www.redsauce.net/de/cves/CVE-2026-35163","sk":"https://www.redsauce.net/sk/cves/CVE-2026-35163","el":"https://www.redsauce.net/el/cves/CVE-2026-35163"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-35163"}}
