CVE-2026-57241
MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
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 The renderer still trusts the outdated page count, leading to out-of-bounds access and application crash.
Risk Assessment
The risk involves a potential denial of service (DoS) attack where a malicious PDF file can intentionally crash the application, disrupting user operations.
Recommendation
It is recommended to update the application to the latest version that includes a fix for page object synchronization and validates the page count before rendering.
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-2026-57250High
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.
- 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-2026-57237High
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)
The application opens the PDF, and JavaScript performs operations on the page and the document, causing the page-related objects within the application to lose synchronization; however, the renderer still trusts the outdated page count, and eventually the application crashes due to out-of-bounds access.
