Summary\n\n`Loofah::HTML5::Scrub.allowed_uri?` does not correctly reject `javascript:` URIs when the scheme is split by HTML entity-encoded control characters such as ` ` (carriage return), ` ` (line feed), or `	` (tab).\n\n## Details\n\nThe `allowed_uri?` method strips literal control characters before decoding HTML entities. Payloads like `java script:alert(1)` survive the control character strip, then ` ` is decoded to a carriage return, producing `java\\rscript:alert(1)`.\n\nNote that the Loofah sanitizer's default `sanitize()` path is **not affected** because Nokogiri decodes HTML entities during parsing before Loofah evaluates the URI protocol. This issue only affects direct callers of the `allowed_uri?` string-level helper when passing HTML-encoded strings.\n\n## Impact\n\nApplications that call `Loofah::HTML5::Scrub.allowed_uri?` to validate user-controlled URLs and then render approved URLs into `href` or other browser-interpreted URI attributes may be vulnerable to cross-site scripting (XSS).\n\nThis only affects Loofah `2.25.0`.\n\n## Mitigation\n\nUpgrade to Loofah >= `2.25.1`.\n\n## Credit\n\nResponsibly reported by HackOne user `@smlee`.", "references": [ { "reference_url": "https://github.com/flavorjones/loofah", "reference_id": "", "reference_type": "", "scores": [ { "value": "2.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U" }, { "value": "LOW", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/flavorjones/loofah" }, { "reference_url": "https://github.com/flavorjones/loofah/security/advisories/GHSA-46fp-8f5p-pf2m", "reference_id": "", "reference_type": "", "scores": [ { "value": "LOW", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" }, { "value": "2.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U" }, { "value": "LOW", "scoring_system": "generic_textual", "scoring_elements": "" } ], "url": "https://github.com/flavorjones/loofah/security/advisories/GHSA-46fp-8f5p-pf2m" }, { "reference_url": "https://github.com/advisories/GHSA-46fp-8f5p-pf2m", "reference_id": "GHSA-46fp-8f5p-pf2m", "reference_type": "", "scores": [ { "value": "LOW", "scoring_system": "cvssv3.1_qr", "scoring_elements": "" } ], "url": "https://github.com/advisories/GHSA-46fp-8f5p-pf2m" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/65210?format=api", "purl": "pkg:gem/loofah@2.25.1", "is_vulnerable": true, "affected_by_vulnerabilities": [ { "vulnerability": "VCID-amsh-qpt1-9qb7" } ], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:gem/loofah@2.25.1" } ], "aliases": [ "GHSA-46fp-8f5p-pf2m" ], "risk_score": 1.4, "exploitability": "0.5", "weighted_severity": "2.7", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-amsh-qpt1-9qb7" }, { "url": "http://public2.vulnerablecode.io/api/vulnerabilities/52847?format=api", "vulnerability_id": "VCID-q52h-9tcw-zfab", "summary": "Inefficient Regular Expression Complexity in Loofah\n## Summary\n\nLoofah `< 2.19.1` contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes.
