CVE-2026-25535
HighCVSS 7.5Exploitation Probability (EPSS)
Elevated risk51th percentile - higher than 51% of all known CVEs
Summary
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.
Risk Assessment
An attacker can exhaust server or client application memory, leading to service disruption. The risk is especially high in environments where users can pass unsanitized image data or URLs.
Recommendation
Upgrade jsPDF to version 4.2.0 or later immediately. If upgrading is not possible, strictly sanitize image data and URLs before passing them to the `addImage` or `html` methods.
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-2026-25755High
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.
- 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 first argument of the `addImage` method results in denial of service. If given the possibility to pass unsanitized image data or URLs to the `addImage` method, a user can provide a harmful GIF file that results in out of memory errors and denial of service. Harmful GIF files have large width and/or height entries in their headers, which lead to excessive memory allocation. Other affected methods are: `html`. The vulnerability has been fixed in jsPDF 4.2.0. As a workaround, sanitize image data or URLs before passing it to the addImage method or one of the other affected methods.
