CVE-2024-41482
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTypora before 1.9.3 Markdown editor has a cross-site scripting (XSS) vulnerability via the MathJax component.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceTypora markdown editor before version 1.9.3 contains a cross-site scripting (XSS) vulnerability in its MathJax component, which is used for rendering mathematical expressions. An attacker could craft malicious content within math expressions that executes arbitrary JavaScript in the context of the user's session when the document is rendered.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Typora is installedCheck for Typora application in your system: on Windows look in Program Files or AppData, on macOS check /Applications folder, on Linux check /usr/share/applications or ~/.local/share/applicationsAffected if Typora is present on the system
-
Determine installed Typora versionOpen Typora and go to Help > About, or check the application metadata file: on Windows right-click the .exe and view Properties > Details, on macOS right-click app > Get Info, on Linux check the .desktop file or package metadataAffected if Version number is found to be less than 1.9.3 (for example, 1.9.2, 1.9.1, 1.8.x, etc.)
-
Confirm MathJax rendering is enabledOpen Typora preferences and navigate to the Markdown or Math settings panel. Verify that math rendering via MathJax is turned on (this is enabled by default in Typora when using $ or $$ delimiters for math expressions)Affected if MathJax math rendering is enabled (this is the default setting)
-
Identify if you open untrusted markdown filesReview your workflow: check whether you open markdown files from unknown or untrusted sources that may contain math expressions delimited by $ or $$Affected if You regularly open markdown files from unknown sources containing math expressions
You are affected if Typora is installed with a version lower than 1.9.3 and you use it to view markdown files with MathJax math expressions (the default configuration).
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.9.3
Update Typora to version 1.9.3 or later, which contains the patched MathJax component. Avoid opening untrusted Markdown files with MathJax expressions from unknown sources until the update is applied.
Typora 1.9.3
- 1. Download Typora version 1.9.3 or later from the official website (typora.io) or your system's package manager
- 2. Back up your current Typora data and settings if desired
- 3. Install the updated version of Typora
- 4. Verify the installation by checking Help > About Typora shows version 1.9.3 or later
- 5. Test that MathJax rendering works properly in the updated version
