Mezzanine CMS, in versions prior to 6.1.1, contains a Stored Cross-Site Scripting (XSS) vulnerability in the admin interface. The vulnerability exists in the "displayable_links_js" function, which fails to properly sanitize blog post titles before including them in JSON responses served via "/admin/displayable_links.js". An authenticated admin user can create a blog post with a malicious JavaScript payload in the title field, then trick another admin user into clicking a direct link to the "/admin/displayable_links.js" endpoint, causing the malicious script to execute in their browser.

A Server-Side Request Forgery (SSRF) vulnerability was identified in the @opennextjs/cloudflare package. The vulnerability stems from an unimplemented feature in the Cloudflare adapter for Open Next, which allowed unauthenticated users to proxy arbitrary remote content via the `/_next/image` endpoint. This issue allowed attackers to load remote resources from arbitrary hosts under the victim site’s domain for any site deployed using the Cloudflare adapter for Open Next. For example: `https://victim-site.com/_next/image?url=https://attacker.com`. In this example, attacker-controlled content from attacker.com is served through the victim site’s domain (`victim-site.com`), violating the same-origin policy and potentially misleading users or other services. ### Impact - SSRF via unrestricted remote URL loading - Arbitrary remote content loading - Potential internal service exposure or phishing risks through domain abuse ### Mitigation The following mitigations have been put in...

Cybersecurity researchers are calling attention to a "large-scale campaign" that has been observed compromising legitimate websites with malicious JavaScript injections. According to Palo Alto Networks Unit 42, these malicious injects are obfuscated using JSFuck, which refers to an "esoteric and educational programming style" that uses only a limited set of characters to write and execute code.
