In a previous post, I described a pass-the-permission-ticket vulnerability in UMA 2.0 in which a malicious UMA resource server could kindly ask a UMA client to give it access tokens actually intended for another UMA resource server. In this post, I am describing a similar attack when the authorization server is malicious.

In the User-Managed Access (UMA) 2.0 protocol, a malicious resource server (or a malicious server acting as a resource server) can obtain a requesting party (access) token (RPT) intended for another UMA resource server from a UMA client by passing a permission ticket obtained from the target resource server to the UMA client. This can compromise the privacy (confidentiality) and integrity of UMA protected resources.

In Debian kitty package, the
kitty-open.desktop file would associate kitty +open with several MIME types.
This could be used to arbitrary trigger code execution by serving a
file with such a MIME type.
This has been introduced in kitty in 73a197fcd (2022-02-06) released as part of v0.24.3. This has been fixed in v0.26.5-5 of the Debian kitty package. Fixed upstream in 537cabca7 released in v0.29.0. Other distributions such as Ubuntu Lunar are still impacted.
