Red Hat Security Advisory 2023-3495-01 - Logging Subsystem 5.7.2 - Red Hat OpenShift. Issues addressed include cross site scripting and denial of service vulnerabilities.
OAuth RFC 8252 says https://www.rfc-editor.org/rfc/rfc8252#section-8.6 > the authorization server SHOULD NOT process authorization requests automatically without user consent or interaction, except when the identity of the client can be assured. **This includes the case where the user has previously approved an authorization request for a given client id** But Doorkeeper automatically processes authorization requests without user consent for public clients that have been previous approved. Public clients are inherently vulnerable to impersonation, their identity cannot be assured.

Doorkeeper is an OAuth 2 provider for Ruby on Rails / Grape. Prior to version 5.6.6, Doorkeeper automatically processes authorization requests without user consent for public clients that have been previous approved. Public clients are inherently vulnerable to impersonation, their identity cannot be assured. This issue is fixed in version 5.6.6.
NOTE: rails-ujs is part of Rails/actionview since 5.1.0. There is a potential DOM based cross-site scripting issue in rails-ujs which leverages the Clipboard API to target HTML elements that are assigned the contenteditable attribute. This has the potential to occur when pasting malicious HTML content from the clipboard that includes a data-method, data-remote or data-disable-with attribute. This vulnerability has been assigned the CVE identifier CVE-2023-23913. Not affected: < 5.1.0 Versions Affected: >= 5.1.0 Fixed Versions: 6.1.7.3, 7.0.4.3 Impact If the specified malicious HTML clipboard content is provided to a contenteditable element, this could result in the arbitrary execution of javascript on the origin in question. Releases The FIXED releases are available at the normal locations. Workarounds We recommend that all users upgrade to one of the FIXED versions. In the meantime, users can attempt to mitigate this vulnerability by removing the contenteditable at...
There is a deserialization of untrusted data vulnerability in the Kredis JSON deserialization code. This vulnerability has been assigned the CVE identifier CVE-2023-27531. 'Not affected: None.' 'Versions Affected: All.' 'Fixed Versions: 1.3.0.1' Impact Carefully crafted JSON data processed by Kredis may result in deserialization of untrusted data, potentially leading to deserialization of unexpected objects in the system. Any applications using Kredis with JSON are affected. Releases The fixed releases are available at the normal locations. Workarounds There are no feasible workarounds for this issue. Patches To aid users who aren’t able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset. * 1-3-0-1-kredis.patch - Patch for 1.3.0 series Credits Thank you ooooooo_k 7 for reporting this!
P2S CMS version 0.1 suffers from a cross site scripting vulnerability.
A Regular Expression Denial of Service (ReDoS) issue was discovered in the sanitize_html function of redcloth gem v4.0.0. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.
### Summary Some avo fields are vulnerable to XSS when rendering html based content. ### Details During the analysis of the web application, a rendered field was discovered that did not filter JS / HTML tags in a safe way and can be abused to execute js code on a client side. The trix field uses the trix editor in the backend to edit rich text data which basically operates with html tags. To display the stored data in a rendered view, the HasHTMLAttributes concern is used. This can be exploited by an attacker to store javascript code in any trix field by intercepting the request and modifying the post data, as the trix editor does not allow adding custom html or js tags on the frontend. ### PoC  _Adding javascript in the post request which is used when editing a "post" resource (body is declared as a trix field)_  when rendering html based content. Attackers do need form edit privilege in order to successfully exploit this vulnerability, but the results are stored and no specific timing is required. This issue has been addressed in commit `7891c01e` which is expected to be included in the next release of avo. Users are advised to configure CSP headers for their application and to limit untrusted user access as a mitigation.
