CVE-2026-25940 | jsPDF's PDF Injection in AcroForm module allows Arbitrary JavaScript Execution (RadioButton.createOption and "AS" property)

jsPDF is a library to generate PDFs in JavaScript. Prior to 4.2.0, user control of properties and methods of the Acroform module allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to one of the following property, a user can inject arbitrary PDF objects, such as JavaScript actions, which are executed when the victim hovers over the radio option. The vulnerability has been fixed in [email protected]. As a workaround, sanitize user input before passing it to the vulnerable API members.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
