Evidence used

  • No CISA KEV confirmation is currently recorded.
  • EPSS is 0.62% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs parallax jsPDF and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
A flaw was found in jsPDF, a JavaScript library used for generating PDF documents. This vulnerability allows a remote attacker to inject arbitrary PDF objects, including JavaScript actions, into a generated PDF. This can occur if unsanitized user input is provided to the `createAnnotation` method's `color` parameter. When a user opens or interacts with the specially crafted PDF, these injected actions may execute, potentially leading to arbitrary code execution or sensitive information disclosure.
Remediation
If you are using an earlier version of RHACS, you are advised to upgrade to the version of RHACS mentioned in the synopsis and release notes in order to take advantage of the enhancements, bug fixes, and/or security patches in the release.

No EUVD known-exploited evidence

jsPDF is a library to generate PDFs in JavaScript. Prior to version 4.2.1, user control of arguments of the `createAnnotation` method allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to the following method, a user can inject arbitrary PDF objects, such as JavaScript actions, which might trigger when the PDF is opened or interacted with the `createAnnotation`: `color` parameter. The vulnerability has been fixed in jsPDF@4.2.1. As a workaround, sanitize user input before passing it to the vulnerable API members.

Prior to version 4.2.1, user control of arguments of the `createAnnotation` method allows users to inject arbitrary PDF objects, such as JavaScript actions.

The vulnerability has been fixed in jsPDF@4.2.1. As a workaround, sanitize user input before passing it to the vulnerable API members.

Why

The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.

How

An attacker operating through a network path may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Encoding or Escaping of Output → cause the confidentiality, integrity or availability impact described by the vendor

CWE-116: Improper Encoding or Escaping of Output. The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.

JVN iPedia · Japanese · JVNDB-2026-008127ParallaxのjsPDFにおけるエンコードおよびエスケープに関する脆弱性

jsPDFはJavaScriptでPDFを生成するライブラリです。バージョン4.2.1以前では、`createAnnotation`メソッドの引数をユーザーが制御できたため、ユーザーがJavaScriptアクションなどの任意のPDFオブジェクトを注入する可能性がありました。サニタイズされていない入力をこのメソッドに渡す場合、ユーザーはJavaScriptアクションなどの任意のPDFオブジェクトを注入でき、それがPDFの開封時や`createAnnotation`の`color`パラメータと対話した際にトリガーされる可能性があります。この脆弱性はjsPDF@4.2.1で修正されています。回避策としては、脆弱なAPIメンバーに渡す前にユーザー入力をサニタイズすることが推奨されます。
