{"apiVersion":"1.0","identifier":"CVE-2026-53458","description":"Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio backend API handlers in custom_components/blueprint_studio/backend/api.py returned raw exception strings to authenticated Home Assistant users. Some exception messages could contain internal filesystem paths or implementation details. The disclosed information could help an authenticated user fingerprint a Home Assistant installation and refine follow-up attacks. This issue is fixed in version 2.5.2.","publishedAt":"2026-08-18T21:16:35","lastModifiedAt":"2026-08-19T14:17:33","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53458","cvssScore":5.3,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/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":0.00339,"riskScore":0.55,"affectedProduct":"Blueprint Studio","affectedVersions":"<2.5.2","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53458","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53458","en":"https://www.redsauce.net/en/cves/CVE-2026-53458","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53458","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53458","de":"https://www.redsauce.net/de/cves/CVE-2026-53458","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53458","el":"https://www.redsauce.net/el/cves/CVE-2026-53458"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53458"}}
