CVE-2021-27671 describes a cross-site scripting (XSS) vulnerability in the comrak Rust crate prior to version 0.9.1. This flaw arises because the URI protection mechanism is case-sensitive, allowing attackers to bypass safeguards by using variations like "Data:" instead of "data:" in URIs. Rated 6.1 MEDIUM, this vulnerability has a network attack vector, low complexity, and requires user interaction, potentially leading to limited impact on confidentiality and integrity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
