DirtyFrag: Universal Linux Local Privilege Escalation via Page-Cache Write
A technical breakdown of DirtyFrag, a pair of Linux kernel local privilege escalation vulnerabilities (CVE-2026-43284 and CVE-2026-43500, CVSS 7.8 HIGH) that allow any unprivileged local user to obtain root on most major Linux distributions. By chaining an xfrm-ESP and an RxRPC in-place decryption path flaw, both rooted in the same page-cache write primitive as Dirty Pipe and Copy Fail, the exploit overwrites read-only page cache pages without a race condition, achieving near-100% reliability.

Exploit CVE-2025-68461 : Roundcube Webmail SVG Animate XSS Sanitizer Bypass
A technical breakdown of CVE-2025-68461, a CVSS 7.2 high stored Cross-Site Scripting vulnerability in Roundcube Webmail (< 1.5.12 and < 1.6.12). The rcube_washtml sanitizer blocks SVG \ tags that target the href attribute, but the attribute_value() comparison does not strip XML namespace prefixes before matching. An attacker can use attributeName="xlink:href" to bypass the check entirely, delivering unsanitized javascript: URIs in the values attribute directly into the rendered email DOM. JavaScript execution is currently prevented by an accidental namespace corruption in PHP's DOMDocument::loadHTML() which strips the xlink namespace declaration, but the sanitizer bypass is confirmed and the vulnerability remains exploitable under alternative parser configurations such as the Masterminds HTML5 parser or PHP 8.4's Dom\HTMLDocument.
CVE-2026-26019 : LangChain RecursiveUrlLoader Server-Side Request Forgery Vulnerability
A technical breakdown of CVE-2026-26019, a CVSS 4.1 medium Server-Side Request Forgery vulnerability in the LangChain Community JavaScript package (< 1.1.14). The RecursiveUrlLoader class uses a naive string prefix check to validate crawled URLs, allowing an attacker to bypass the default preventOutside restriction with a suffixed domain and redirect the crawler to internal network assets, potentially exposing sensitive credentials and metadata endpoints.
