{"schema":"threatline.record/2","record":{"id":"CVE-2026-115720","aliases":["GHSA-hvrf-fhv3-3v7p"],"summary":"Frappe Builder before 1.36.1 SSRF Guard Bypass via HTTP Redirect","details":"Frappe Builder before 1.36.1 contains a server-side request forgery vulnerability in builder/api.py where the assert_not_private_url() guard validates only the initial hostname before callers invoke requests.get(url) with default redirect-following and no IP pinning, allowing an attacker-supplied public URL to HTTP-redirect to internal or link-local addresses the guard never validated. 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.","categories":["Unclassified"],"product":"builder","vendor":"frappe","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115720","source_modified_at":"2026-10-26T12:02:25.906Z","fetched_at":"2026-10-26T12:48:13.248886Z","product":"builder","vendor":"frappe","versions":[{"status":"affected","version":"1.0.0","versionType":"semver","lessThan":"1.36.1"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115720","source_modified_at":"2026-10-26T12:02:25.906Z","fetched_at":"2026-10-26T12:48:13.248886Z","package":{"name":"builder","ecosystem":null},"version":"1.36.1","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T12:02:25.906Z","modified_at":"2026-10-26T12:02:25.906Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115720","fetched_at":"2026-10-26T12:48:13.248886Z","source_modified_at":"2026-10-26T12:02:25.906Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/frappe/builder/releases/tag/v1.36.1","tags":["patch"]},{"source":"CVE List","url":"https://github.com/frappe/builder/security/advisories/GHSA-hvrf-fhv3-3v7p","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/frappe-builder-before-ssrf-guard-bypass-via-http-redirect","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T12:02:25.906Z","content_hash":"1021a5c8c17552c98b9678a1b87a39cf079397a026160de985f6aa11005b97dd"}}
