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.

AnalysisAI

XXE injection in Foxit PDF Editor and Foxit PDF Reader exposes any local file readable by the victim user when they open a maliciously crafted document disguised as a PDF. The parser processes documents that are not structurally valid PDFs, resolving attacker-controlled external XML entities that reference local filesystem paths via file:// or similar protocols, enabling out-of-band exfiltration of sensitive local files. …

Vulnerability AssessmentAI

Exploitation	The victim must actively open a maliciously crafted file using Foxit PDF Editor or Foxit PDF Reader - this is the sole prerequisite enforced by UI:R in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N scores 6.5 Medium, which fairly reflects the risk profile: network-deliverable with no authentication required, but constrained by mandatory user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker sends a phishing email to a target employee with an attachment disguised as a PDF invoice or contract; the file contains malicious XXE entity declarations referencing sensitive paths such as C:\Users\victim\.ssh\id_rsa or /home/victim/.aws/credentials. When the victim opens the file in Foxit PDF Reader or Editor, the parser resolves the external entities, reads the target files, and the attacker receives the exfiltrated content via a DNS or HTTP callback to an attacker-controlled server. …
Remediation	Upgrade Foxit PDF Editor and Foxit PDF Reader to the versions published in Foxit's security bulletin at https://www.foxit.com/support/security-bulletins.html. … Detailed patch versions, workarounds, and compensating controls in full report.
