Because these script\u2011driven updates bypass the existing redaction, encryption, and printing checks, a crafted PDF can leave a fragment of sensitive information unredacted or unencrypted, or produce a printed output that does not match the on\u2011screen version. The vulnerability is therefore a source of potential data exposure and log integrity issues.", "risk_and_exploitability": "The CVSS score of 4.7 indicates moderate severity, and the EPSS score of less than 1\u202f% suggests a low likelihood of widespread exploitation. The vulnerability is not listed in the CISA KEV catalogue. Exploitation requires a user to open a malicious PDF that contains JavaScript designed to execute at print or redact time, a scenario that is plausible if users receive untrusted documents. The attack surface is therefore limited to environments where PDF JavaScript is enabled and users routinely open and print PDFs."}}}}, "created": "2026-04-02T07:50:20.313435+00:00", "updated": "2026-04-10T09:45:52.497798+00:00", "vendors": ["foxitsoftware", "foxitsoftware$PRODUCT$foxit_pdf_editor"]}
