Improper neutralization of data URIs may allow XSS in Loofah ## Summary Loofah `>= 2.1.0, < 2.19.1` is vulnerable to cross-site scripting via the `image/svg+xml` media type in data URIs. ## Mitigation Upgrade to Loofah `>= 2.19.1`. ## Severity The Loofah maintainers have evaluated this as [Medium Severity 6.1](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N). ## References - [CWE - CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (4.9)](https://cwe.mitre.org/data/definitions/79.html) - [SVG MIME Type (image/svg+xml) is misleading to developers · Issue #266 · w3c/svgwg](https://github.com/w3c/svgwg/issues/266) - https://hackerone.com/reports/1694173 - https://github.com/flavorjones/loofah/issues/101 ## Credit This vulnerability was responsibly reported by Maciej Piechota (@haqpl). |

Uncontrolled Recursion in Loofah ## Summary Loofah `>= 2.2.0, < 2.19.1` uses recursion for sanitizing `CDATA` sections, making it susceptible to stack exhaustion and raising a `SystemStackError` exception. This may lead to a denial of service through CPU resource consumption. ## Mitigation Upgrade to Loofah `>= 2.19.1`. Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized. ## Severity The Loofah maintainers have evaluated this as [High Severity 7.5 (CVSS3.1)](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). ## References - [CWE - CWE-674: Uncontrolled Recursion (4.9)](https://cwe.mitre.org/data/definitions/674.html) |

Inefficient Regular Expression Complexity in Loofah ## Summary Loofah `< 2.19.1` contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. ## Mitigation Upgrade to Loofah `>= 2.19.1`. ## Severity The Loofah maintainers have evaluated this as [High Severity 7.5 (CVSS3.1)](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). ## References - [CWE - CWE-1333: Inefficient Regular Expression Complexity (4.9)](https://cwe.mitre.org/data/definitions/1333.html) - https://hackerone.com/reports/1684163 ## Credit This vulnerability was responsibly reported by @ooooooo-q (https://github.com/ooooooo-q). |
