CVE-2026-25755
HighCVSS 8.1Exploitation Probability (EPSS)
Elevated risk55th percentile - higher than 55% of all known CVEs
Summary
The jsPDF library prior to version 4.2.0 is vulnerable to injection of arbitrary PDF objects via user-controlled argument of the `addJS` method. An attacker can escape JavaScript string delimiters to alter document structure or execute malicious actions.
Risk Assessment
The risk involves users opening crafted PDF files being exposed to unauthorized document modifications or code execution, potentially leading to data integrity breaches or social engineering attacks.
Recommendation
Immediately update jsPDF to version 4.2.0 or later. If updating is not possible, escape parentheses in user-provided JavaScript code before passing it to the `addJS` method.
Other vulnerabilities in jsPDF
See all- CVE-2026-31938Critical
The jsPDF library prior to version 4.2.1 is vulnerable to HTML injection (including scripts) via user control of the `options` argument in the `output` function. An attacker can supply malicious values that, when the PDF is generated and opened in the victim's browser, execute in the victim's browser context.
- CVE-2026-31898High
jsPDF library prior to version 4.2.1 is vulnerable to injection of arbitrary PDF objects, including JavaScript actions, via the `color` parameter of the `createAnnotation` method. An attacker can exploit this to execute malicious code when the PDF is opened.
- CVE-2026-25940High
The jsPDF library prior to version 4.2.0 contains a vulnerability that allows injection of arbitrary PDF objects, including JavaScript actions, through control of Acroform module properties and methods. The attack can be triggered when the victim hovers over a radio option.
- CVE-2026-25535High
The jsPDF library prior to version 4.2.0 is vulnerable to a denial of service attack via user control of the first argument of the `addImage` method. Passing a malicious GIF file with large width/height headers causes excessive memory allocation and denial of service. The `html` method is also affected.
- CVE-2026-24737High
The jsPDF library prior to version 4.1.0 has a vulnerability that allows injection of arbitrary PDF objects, including JavaScript actions, through user control of Acroform module properties and methods. Attackers can exploit unsanitized input in methods such as AcroformChoiceField.addOption, AcroformChoiceField.setOptions, AcroFormCheckBox.appearanceState, and AcroFormRadioButton.appearanceState.
- CVE-2025-68428High
The jsPDF library prior to version 4.0.0 is vulnerable to local file inclusion and path traversal. An attacker can exploit the loadFile method, as well as addImage, html, and addFont, to read arbitrary files from the server's file system. The file contents are then embedded in generated PDF documents.
Original NVD description (English source)
jsPDF is a library to generate PDFs in JavaScript. Prior to 4.2.0, user control of the argument of the `addJS` method allows an attacker to inject arbitrary PDF objects into the generated document. By crafting a payload that escapes the JavaScript string delimiter, an attacker can execute malicious actions or alter the document structure, impacting any user who opens the generated PDF. The vulnerability has been fixed in [email protected]. As a workaround, escape parentheses in user-provided JavaScript code before passing them to the `addJS` method.
