CVE-2026-57252
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
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.
Risk Assessment
An attacker can exploit this vulnerability to crash the application, potentially leading to denial of service (DoS) in environments processing malicious PDF files.
Recommendation
Immediately update the software to a patched version and restrict opening PDF files from untrusted sources.
Other vulnerabilities in PDF Viewer
See all- 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-2026-57241Medium
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 The renderer still trusts the outdated page count, leading to out-of-bounds access and application crash.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 file, during the process of JavaScript deleting pages and removing attachment annotations, it will cause the attachment panel to continue accessing invalid pointers, eventually leading to the application crashing.
