An authenticated attacker can call the convert_to_webp endpoint, which lacks a permission decorator, with a URL that redirects to internal targets such as cloud metadata services to perform SSRF, internal port scanning, or trigger a request-hang denial of service due to the missing timeout.","state":0,"publishedAt":"2026-10-26T12:02:25.906+00:00","modifiedAt":"2026-10-26T12:02:25.906+00:00","affected":[{"ecosystem":"Vendor product","name":"builder","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"frappe\",\n                    \"product\": \"builder\",\n                    \"packageURL\": \"pkg:github/frappe/builder\",\n                    \"repo\": \"https://github.com/frappe/builder\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.36.1\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","score":5,"severity":"MEDIUM"}],"references":["https://github.com/frappe/builder/releases/tag/v1.36.1","https://github.com/frappe/builder/security/advisories/GHSA-hvrf-fhv3-3v7p","https://www.vulncheck.com/advisories/frappe-builder-before-ssrf-guard-bypass-via-http-redirect"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115720","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115720","identifiers":["CVE-2026-115720"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
