CVE-2026-91797: External Control of File Name or Path

Foxit PDF Editor/Reader failed to validate the directory traversal path in the attachment file name, resulting in malicious attachments being able to be written to directories outside the expected secure area when the PDF is opened...

CVE-2026-91796: Protection Mechanism Failure

The interface of Foxit PDF Editor/Reader lacks the permission verification for secure reading mode, which allows specially crafted PDFs to trigger external SMB authentication without any security prompts and thereby leak the hash of the user's credentials...

CVE-2026-91795: Untrusted Pointer Dereference

Foxit PDF Editor/Reader's FileOpen plugin did not adequately validate certain encryption metadata in specially crafted PDF files. This could leave an internal pointer in an invalid state, resulting in chained read and write access violations and potentially enabling arbitrary code execution...

CVE-2026-91793: Use After Free

When opening a specially crafted PDF, Foxit PDF Editor/Reader executes scripts that modify annotation rich-text attributes containing malformed font data. During subsequent annotation appearance reconstruction, it accesses an object after it has been released, resulting in a use-after-free...

CVE-2026-91790: Use After Free

When rendering the page image, Foxit PDF Editor/Reader fails to perform validation on image objects whose optional content attributes are malformed. As a result, the program may access an already-freed internal data structure, triggering a crash due to UAF...

CVE-2026-91788: Exposure of Resource to Wrong Sphere

When implementing the JavaScript interface, Foxit PDF Editor/Reader did not perform the attribute authorization checks required by the specification. As a result, a trusted malicious PDF could potentially access sensitive content from other documents within the same process and transmit it...

CVE-2026-91818: Use After Free

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s JavaScript handling of PDF annotations. Reentrant page-event processing during annotation enumeration may release the associated page object, which is subsequently accessed, resulting in an application crash...

CVE-2026-91817: Out-of-bounds Read

A heap-based out-of-bounds read vulnerability exists in Foxit PDF Editor/Reader’s handling of wide strings in embedded PDF JavaScript. Insufficient validation of string-deletion ranges can cause an integer underflow, resulting in an out-of-bounds read and application crash...

CVE-2026-91816: Use After Free

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF annotations. Reentrant annotation deletion triggered by embedded JavaScript can cause the application to access an annotation object after it has been released, resulting in a use-after-free condition and applicati...

CVE-2026-91815: Out-of-bounds Write

Foxit PDF Editor/Reader does not perform sufficient verification of the JPEG2000 image metadata in the PDF file, which leads to out-of-bounds write in the heap buffer during decoding, potentially causing the program to crash and introducing the risk of arbitrary code execution...

CVE-2026-91806: Use After Free

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF form fields. Embedded JavaScript may access form-field references after the corresponding fields have been released, resulting in an application crash...

CVE-2026-91805: Use After Free

A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s PDF page-tree handling. A specially crafted PDF can trigger page-structure changes during rendering, causing the application to access released page objects and resulting in memory corruption and an application crash...

CVE-2026-91800: Incorrect Permission Assignment for Critical Resource

A local privilege escalation vulnerability exists in the installer of Foxit PDF Editor for macOS due to insufficient validation of a user-modifiable configuration value during high-privilege upgrades. A local attacker could exploit this issue to execute arbitrary commands with root privileges...
