CVE-2026-57250
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
The vulnerability in a PDF viewing application occurs when JavaScript resets form fields, causing re-entry into the interface and damaging the native object. The application fails to validate the object before calling a function, leading to a crash.
Risk Assessment
The risk involves potential denial of service through a malicious PDF file that triggers an application crash, disrupting operations and requiring a restart.
Recommendation
It is recommended to immediately update the application to a version that includes a fix validating object state before JavaScript function calls.
Other vulnerabilities in PDF Viewer
See all- CVE-2026-57252High
When opening a PDF file, during JavaScript-based deletion of pages and attachment annotations, the attachment panel accesses invalid pointers, causing the application to crash.
- CVE-2026-57242High
The vulnerability in the PDF viewing application stems from incomplete lifecycle management and null value validation of objects. JavaScript modifies the form, and when the page state changes, the application repeatedly dereferences invalid objects, eventually causing a crash.
- CVE-2026-57241Medium
The vulnerability in a PDF viewing application occurs when JavaScript performs operations on the page and document, causing page-related objects to lose synchronization. The renderer still trusts the outdated page count, leading to out-of-bounds access and application crash.
- CVE-2026-57237High
The vulnerability in the PDF viewing application occurs when JavaScript modifies form field properties, causing the state of underlying objects referenced by the program to become invalid. This eventually leads to reading an illegal memory address and crashing the application.
- CVE-2026-13128High
Embedding JavaScript within a PDF file will cause the page to be deleted. Subsequent scripts will continue to access the relevant properties of the document view, eventually leading to the crash of the application.
- CVE-2026-13127High
The vulnerability occurs when the application opens a PDF file, and JavaScript rewrites the document, modifying the page structure and invalidating page objects. Thumbnails still use these invalid objects, ultimately causing the application to crash.
Original NVD description (English source)
When the application opens a PDF and JavaScript resets the form fields, the script re-enters the interface. The underlying native object is damaged, but the application does not perform validation. The function call on the damaged object leads to the application crashing.
