Summary
# Possible XSS Vulnerability in Rails::Html::SanitizerThere is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer.This vulnerability has been assigned the CVE identifier CVE-2022-32209.Versions Affected: ALLNot affected: NONEFixed Versions: v1.4.3## ImpactA 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 to allow both `select` and `style` elements.Code is only impacted if allowed tags are being overridden. This may be done via application configuration:```ruby# In config/application.rbconfig.action_view.sanitized_allowed_tags = ["select", "style"]```see https://guides.rubyonrails.org/configuring.html#configuring-action-viewOr it may be done with a `:tags` option to the Action View helper `sanitize`:```<%= sanitize @comment.body, tags: ["select", "style"] %>```see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitizeOr it may be done with Rails::Html::SafeListSanitizer directly:```ruby# class-level optionRails::Html::SafeListSanitizer.allowed_tags = ["select", "style"]```or```ruby# instance-level optionRails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: ["select", "style"])```All users overriding the allowed tags by any of the above mechanisms to include both "select" and "style" should either upgrade or use one of the workarounds immediately.## ReleasesThe FIXED releases are available at the normal locations.## WorkaroundsRemove either `select` or `style` from the overridden allowed tags.## CreditsThis vulnerability was responsibly reported by [windshock](https://hackerone.com/windshock?type=user).

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
