Security Advisories 🚨

🚨 Regular Expression Denial of Service (ReDoS) in Prism

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.

References

• #2774
• #2688

🚨 Denial of service in prismjs

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.

🚨 Cross-Site Scripting in Prism

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).

👉 No CI detected

You don't seem to have any Continuous Integration service set up!

Without a service that will test the Depfu branches and pull requests, we can't inform you if incoming updates actually work with your app. We think that this degrades the service we're trying to provide down to a point where it is more or less meaningless.

This is fine if you just want to give Depfu a quick try. If you want to really let Depfu help you keep your app up-to-date, we recommend setting up a CI system:

• Circle CI, Semaphore and Travis-CI are all excellent options.
• If you use something like Jenkins, make sure that you're using the Github integration correctly so that it reports status data back to Github.
• If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with depfu/.
