CVE-2022-23520 2 Debian, Rubyonrails 2 Debian Linux, Rails Html Sanitizers 2026-06-17 N/A 6.1 MEDIUM
rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, there is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer due to an incomplete fix of CVE-2022-32209. Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both "select" and "style" elements. Code is only impacted if allowed tags are being overridden. This issue is patched in version 1.4.4. All users overriding the allowed tags to include both "select" and "style" should either upgrade or use this workaround: Remove either "select" or "style" from the overridden allowed tags. NOTE: Code is _not_ impacted if allowed tags are overridden using either the :tags option to the Action View helper method sanitize or the :tags option to the instance method SafeListSanitizer#sanitize.
CVE-2022-23519 2 Debian, Rubyonrails 2 Debian Linux, Rails Html Sanitizers 2026-06-17 N/A 7.2 HIGH
rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags in either of the following ways: allow both "math" and "style" elements, or allow both "svg" and "style" elements. Code is only impacted if allowed tags are being overridden. . This issue is fixed in version 1.4.4. All users overriding the allowed tags to include "math" or "svg" and "style" should either upgrade or use the following workaround immediately: Remove "style" from the overridden allowed tags, or remove "math" and "svg" from the overridden allowed tags.
CVE-2022-23518 3 Debian, Loofah Project, Rubyonrails 3 Debian Linux, Loofah, Rails Html Sanitizers 2026-06-17 N/A 6.1 MEDIUM
rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Versions >= 1.0.3, < 1.4.4 are vulnerable to cross-site scripting via data URIs when used in combination with Loofah >= 2.1.0. This issue is patched in version 1.4.4.
CVE-2022-23517 2 Debian, Rubyonrails 2 Debian Linux, Rails Html Sanitizers 2026-06-17 N/A 7.5 HIGH
rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Certain configurations of rails-html-sanitizer < 1.4.4 use 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. This issue has been patched in version 1.4.4.
CVE-2022-22577 2 Debian, Rubyonrails 2 Debian Linux, Actionpack 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
An XSS Vulnerability in Action Pack >= 5.2.0 and < 5.2.0 that could allow an attacker to bypass CSP for non HTML like responses.
CVE-2022-21831 2 Debian, Rubyonrails 2 Debian Linux, Active Storage 2026-06-17 6.8 MEDIUM 9.8 CRITICAL
A code injection vulnerability exists in the Active Storage >= v5.2.0 that could allow an attacker to execute code via image_processing arguments.
CVE-2021-44528 1 Rubyonrails 1 Rails 2026-06-17 5.8 MEDIUM 6.1 MEDIUM
A open redirect vulnerability exists in Action Pack >= 6.0.0 that could allow an attacker to craft a "X-Forwarded-Host" headers in combination with certain "allowed host" formats can cause the Host Authorization middleware in Action Pack to redirect users to a malicious website.
CVE-2021-22942 1 Rubyonrails 1 Rails 2026-06-17 5.8 MEDIUM 6.1 MEDIUM
A possible open redirect vulnerability in the Host Authorization middleware in Action Pack >= 6.0.0 that could allow attackers to redirect users to a malicious website.
CVE-2021-22904 1 Rubyonrails 1 Rails 2026-06-17 5.0 MEDIUM 7.5 HIGH
The actionpack ruby gem before 6.1.3.2, 6.0.3.7, 5.2.4.6, 5.2.6 suffers from a possible denial of service vulnerability in the Token Authentication logic in Action Controller due to a too permissive regular expression. Impacted code uses `authenticate_or_request_with_http_token` or `authenticate_with_http_token` for request authentication.
CVE-2021-22903 1 Rubyonrails 1 Rails 2026-06-17 5.8 MEDIUM 6.1 MEDIUM
The actionpack ruby gem before 6.1.3.2 suffers from a possible open redirect vulnerability. Specially crafted Host headers in combination with certain "allowed host" formats can cause the Host Authorization middleware in Action Pack to redirect users to a malicious website. This is similar to CVE-2021-22881. Strings in config.hosts that do not have a leading dot are converted to regular expressions without proper escaping. This causes, for example, `config.hosts << "sub.example.com"` to permit a request with a Host header value of `sub-example.com`.
CVE-2021-22902 1 Rubyonrails 1 Rails 2026-06-17 5.0 MEDIUM 7.5 HIGH
The actionpack ruby gem (a framework for handling and responding to web requests in Rails) before 6.0.3.7, 6.1.3.2 suffers from a possible denial of service vulnerability in the Mime type parser of Action Dispatch. Carefully crafted Accept headers can cause the mime type parser in Action Dispatch to do catastrophic backtracking in the regular expression engine.
CVE-2021-22885 2 Debian, Rubyonrails 3 Debian Linux, Actionpack Page-caching, Rails 2026-06-17 5.0 MEDIUM 7.5 HIGH
A possible information disclosure / unintended method execution vulnerability in Action Pack >= 2.0.0 when using the `redirect_to` or `polymorphic_url`helper with untrusted user input.
CVE-2021-22881 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2026-06-17 5.8 MEDIUM 6.1 MEDIUM
The Host Authorization middleware in Action Pack before 6.1.2.1, 6.0.3.5 suffers from an open redirect vulnerability. Specially crafted `Host` headers in combination with certain "allowed host" formats can cause the Host Authorization middleware in Action Pack to redirect users to a malicious website. Impacted applications will have allowed hosts with a leading dot. When an allowed host contains a leading dot, a specially crafted `Host` header can be used to redirect to a malicious website.
CVE-2021-22880 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2026-06-17 5.0 MEDIUM 7.5 HIGH
The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can cause the input validation in the `money` type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input.
CVE-2020-8264 1 Rubyonrails 1 Rails 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
In actionpack gem >= 6.0.0, a possible XSS vulnerability exists when an application is running in development mode allowing an attacker to send or embed (in another page) a specially crafted URL which can allow the attacker to execute JavaScript in the context of the local application. This vulnerability is in the Actionable Exceptions middleware.
CVE-2020-8185 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
A denial of service vulnerability exists in Rails <6.0.3.2 that allowed an untrusted user to run any pending migrations on a Rails app running in production.
CVE-2020-8167 2 Debian, Rubyonrails 2 Debian Linux, Rails 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
A CSRF vulnerability exists in rails <= 6.0.3 rails-ujs module that could allow attackers to send CSRF tokens to wrong domains.
CVE-2020-8166 2 Debian, Rubyonrails 2 Debian Linux, Rails 2026-06-17 4.3 MEDIUM 4.3 MEDIUM
A CSRF forgery vulnerability exists in rails < 5.2.5, rails < 6.0.4 that makes it possible for an attacker to, given a global CSRF token such as the one present in the authenticity_token meta tag, forge a per-form CSRF token.
CVE-2020-8165 3 Debian, Opensuse, Rubyonrails 3 Debian Linux, Leap, Rails 2026-06-17 7.5 HIGH 9.8 CRITICAL
A deserialization of untrusted data vulnernerability exists in rails < 5.2.4.3, rails < 6.0.3.1 that can allow an attacker to unmarshal user-provided objects in MemCacheStore and RedisCacheStore potentially resulting in an RCE.
CVE-2020-8164 3 Debian, Opensuse, Rubyonrails 4 Debian Linux, Backports Sle, Leap and 1 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
A deserialization of untrusted data vulnerability exists in rails < 5.2.4.3, rails < 6.0.3.1 which can allow an attacker to supply information can be inadvertently leaked fromStrong Parameters.
