GitHub Vulnerability Alerts

CVE-2020-15138

Impact

The easing preview of the Previewers plugin has an XSS vulnerability that allows attackers to execute arbitrary code in Safari and Internet Explorer.

This impacts all Safari and Internet Explorer users of Prism >=v1.1.0 that use the Previewers plugin (>=v1.10.0) or the Previewer: Easing plugin (v1.1.0 to v1.9.0).

Patches

This problem is patched in v1.21.0.

Workarounds

To workaround the issue without upgrading, disable the easing preview on all impacted code blocks. You need Prism v1.10.0 or newer to apply this workaround.

References

The vulnerability was introduced by this commit on Sep 29, 2015 and fixed by Masato Kinugawa (#​2506).

CVE-2021-23341

The package prismjs before 1.23.0 are vulnerable to Regular Expression Denial of Service (ReDoS) via the prism-asciidoc, prism-rest, prism-tap and prism-eiffel components.

CVE-2021-32723

Some languages before 1.24.0 are vulnerable to Regular Expression Denial of Service (ReDoS).

Impact

When Prism is used to highlight untrusted (user-given) text, an attacker can craft a string that will take a very very long time to highlight. Do not use the following languages to highlight untrusted text.

  • ASCIIDoc
  • ERB

Other languages are not affected and can be used to highlight untrusted text.

Patches

This problem has been fixed in Prism v1.24.

CVE-2021-3801

Prism is a syntax highlighting library. The prismjs package is vulnerable to ReDoS (regular expression denial of service). An attacker that is able to provide a crafted HTML comment as input may cause an application to consume an excessive amount of CPU.

CVE-2022-23647

Impact

Prism's Command line plugin can be used by attackers to achieve an XSS attack. The Command line plugin did not properly escape its output, leading to the input text being inserted into the DOM as HTML code.

Server-side usage of Prism is not impacted. Websites that do not use the Command Line plugin are also not impacted.

Patches

This bug has been fixed in v1.27.0.

Workarounds

Do not use the Command line plugin on untrusted inputs, or sanitized all code blocks (remove all HTML code text) from all code blocks that use the Command line plugin.
