CVE-2022-47881Network attack vector

Information disclosure via out-of-bounds memory read

Published Jan 18, 2023 · Updated Apr 4, 2025

Out-of-bounds read in Foxit PDF Reader and PDF Editor 11.2.1.53537 and earlier allows remote attackers to disclose memory contents. The public records do not identify the affected parser, object, or malformed PDF field that causes the application to read past an allocated boundary. Exploitation requires user interaction with attacker-controlled content; the documented consequence is confidentiality loss without integrity or availability impact.
