# CVE-2026-57259: Foxit PDF Editor/Reader XDP XFA XXE arbitrary local file read

- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-07-08 · Updated: 2026-07-08

## Affected

- Foxit Software Inc. Foxit PDF Editor: version range not reported
- Foxit Software Inc. Foxit PDF Reader: version range not reported

## Description

The input file does not need to be strictly in a structurally valid PDF format. Instead, after reviewing the content, the original document disguised as a PDF will be sent to the parser. Malicious documents will construct malicious external entities that, through the protocol, point to local paths, thereby allowing access to any local files within the user's permission range.
