CVE-2026-57255
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe application opens a PDF containing an abnormal color space whose attributes reference a valid but semantically malformed function. The function's output is not validated; when subsequently read, it produces an illegal pointer that accesses an out-of-bounds region, crashing the application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe vulnerability exists in PDF color space parsing where a malformed function referenced by color space attributes produces invalid output that is not validated. When this output is subsequently used as a pointer, it dereferences an illegal memory address, causing an out-of-bounds read that crashes the application.

Identify if Foxit PDF software is installedCheck for Foxit PDF Editor or Foxit PDF Reader in the system program list, or search for executable files (e.g., FoxitPDFEditor.exe, FoxitReader.exe) in typical installation directories like C:\Program Files\Foxit Software\ or C:\Program Files (x86)\Foxit Software\Affected if Either Foxit PDF Editor or Foxit PDF Reader is present on the system
-
Determine the installed version of Foxit PDF EditorRight-click the Foxit PDF Editor executable, select Properties, and view the Details tab for the Product Version field. Alternatively, open the application, click Help > About Foxit PDF Editor to display the version numberAffected if The version matches any of these ranges: <= 13.2.4.24048; >= 14.0.0.33046 and <= 14.0.4.33508; >= 2023.1.0.15510 and <= 2023.3.0.23028; >= 2024.1.0.23997 and <= 2024.4.1.27687; >= 2025.1.0.27937 and <= 2025.3.0.35737; >= 2026.1.0.36452 and <= 2026.1.1.36485

Determine the installed version of Foxit PDF ReaderRight-click the Foxit Reader executable, select Properties, and view the Details tab for the Product Version field. Alternatively, open the application, click Help > About Foxit Reader to display the version numberAffected if The version is <= 2026.1.1.36485
The environment is affected if Foxit PDF Editor (any version within the listed ranges) or Foxit PDF Reader (version 2026.1.1.36485 or earlier) is installed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement validation checks for function output before using it as a pointer, ensuring all color space function results are verified for validity and bounds compliance before dereferencing.
