Mail: Email address spoofing via malformed RFC 2047 encoded-words

Summary Mail::Utilities.qvaluedecode and Mail::Utilities.bvaluedecode decoded only the first RFC 2047 encoded-word in a string and used an overly greedy pattern to match the charset token. A crafted, malformed encoded-word embedded in an address display name or local part could cause the decoded...

fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words. This could lead to excessive CPU consumption, resulting in a Denial of Service...

Kirby: Access to image files and limited access to JSON files outside of the site root via path traversal in the media handling

TL;DR This vulnerability affects all Kirby sites that are deployed to a server that allows requests for URLs with encoded slashes %2f, such as nginx, PHP's built-in server or Apache setups that have the option AllowEncodedSlashes enabled. It was possible to create and access thumbnails from media...
