CVE-2026-57259: Improper Restriction of XML External Entity Reference (CWE-611) in Foxit Software Inc. Foxit PDF Editor
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.
AI Analysis
Technical Summary
Foxit PDF Editor improperly restricts XML external entity references (CWE-611) by accepting input files that are not strictly valid PDFs. Maliciously crafted documents can exploit this by embedding external entities that reference local file system paths, enabling access to local files accessible by the user. The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity. There is no vendor-provided remediation or patch information available at this time, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation allows an attacker to access local files on the victim's system within the permissions of the user running Foxit PDF Editor. This can lead to disclosure of sensitive information. There is no indication of impact on integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening PDF files from untrusted sources, especially those that may not be structurally valid PDFs.
