### Impact I found "multipart/form-data request tampering vulnerability" caused by Content-Disposition "filename" lack of escaping in httparty. `httparty/lib/httparty/request` > `body.rb` > `def generate_multipart` https://github.com/jnunemaker/httparty/blob/4416141d37fd71bdba4f37589ec265f55aa446ce/lib/httparty/request/body.rb#L43 By exploiting this problem, the following attacks are possible * An attack that rewrites the "name" field according to the crafted file name, impersonating (overwriting) another field. * Attacks that rewrite the filename extension at the time multipart/form-data is generated by tampering with the filename For example, this vulnerability can be exploited to generate the following Content-Disposition. > Normal Request example: > normal input filename: `abc.txt` > > generated normal header in multipart/form-data > `Content-Disposition: form-data; name="avatar"; filename="abc.txt"` > Malicious Request example > malicious input filename: `overwrite_name_f...

Debian Linux Security Advisory 5310-1 - It was discovered that ruby-image-processing, a ruby package that provides higher-level image processing helpers, is prone to a remote shell execution vulnerability when using the #apply method to apply a series of operations coming from unsanitized user input.

A vulnerability classified as critical has been found in Hesburgh Libraries of Notre Dame Sipity. This affects the function SearchCriteriaForWorksParameter of the file app/parameters/sipity/parameters/search_criteria_for_works_parameter.rb. The manipulation leads to sql injection. Upgrading to version 2021.8 is able to address this issue. The name of the patch is d1704c7363b899ffce65be03a796a0ee5fdbfbdc. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-217179.

Due to improper path santization, archives containing relative file paths can cause files to be written (or overwritten) outside of the target directory.

Apple Security Advisory 2022-12-13-4 - macOS Ventura 13.1 addresses bypass, code execution, out of bounds access, out of bounds write, spoofing, and use-after-free vulnerabilities.

The issue was addressed with improved bounds checks. This issue is fixed in iOS 16.2 and iPadOS 16.2, macOS Ventura 13.1, tvOS 16.2. Connecting to a malicious NFS server may lead to arbitrary code execution with kernel privileges.

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.

## Summary There is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer. This is due to an incomplete fix of CVE-2022-32209. - Versions affected: ALL - Not affected: NONE - Fixed versions: 1.4.4 ## Impact 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 to allow both "select" and "style" elements. Code is only impacted if allowed tags are being overridden using either of the following two mechanisms: 1. Using the Rails configuration `config.action_view.sanitized_allow_tags=`: ```ruby # In config/application.rb config.action_view.sanitized_allowed_tags = ["select", "style"] ``` (see https://guides.rubyonrails.org/configuring.html#configuring-action-view) 2. Using the class method `Rails::Html::SafeListSanitizer.allowed_tags=`: ```ruby # class-level option Rails::Html::SafeListSanitizer...

## Summary There is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer. - Versions affected: ALL - Not affected: NONE - Fixed versions: 1.4.4 ## Impact 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. Applications may be doing this in four different ways: 1. using application configuration: ```ruby # In config/application.rb config.action_view.sanitized_allowed_tags = ["math", "style"] # or config.action_view.sanitized_allowed_tags = ["svg", "style"] ``` see https://guides.rubyonrails.org/configuring.html#configuring-action-view 2. using a `:tags` option to the Action View helper `sanitize`: ``` <%= saniti...
