CVE-2021-31812 describes a denial-of-service vulnerability in Apache PDFBox, affecting versions 2.0.23 and prior 2.0.x releases, as well as products from Oracle and Fedora Project that incorporate PDFBox. This medium-severity vulnerability (CVSS 5.5) can be triggered by a specially crafted PDF file, leading to an infinite loop and resource exhaustion (availability impact). While the attack requires user interaction (UI:R) to open the malicious file, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
