CVE-2026-25535
Description
A flaw was found in jsPDF. The addImage and html methods accept user input in their first argument without proper sanitization. An attacker can supply a specially crafted GIF file, specifically with invalid width and height header values, forcing the application to allocate an excessive amount of memory, leading to an out-of-memory condition, causing an application crash and denial of service.
Statement
To exploit this flaw, an attacker must be able to process a specially crafted GIF file with an application using the addImage or html methods. This issue can cause the application to allocate an excessive amount of memory, eventually resulting in a denial of service with no other security impact. Due to this reason, this vulnerability has been rated with an important severity.
Mitigation
To mitigate this vulnerability, sanitize image data or validate resources fetched from URLs before calling the addImage or html methods, making sure that the width and height header values do not exceed safe and predefined limits.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
