CVE-2021-32823 is a denial-of-service vulnerability in the bindata RubyGem, affecting versions prior to 2.4.10, including its use in GitLab. This flaw stems from slow object creation for specific BinData classes, which, when combined with user-controlled input and constantize, can lead to a CPU-based DoS. The CVSS score is 3.7 (Low), indicating a network-based attack with high attack complexity and low impact on availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
