How do I detect GHSA-98pf-gfh3-x3mp in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for readthedocs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-98pf-gfh3-x3mp if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Description

Impact

This vulnerability allowed a malicious user to serve arbitrary HTML files from the main application domain (readthedocs[.]org/readthedocs[.]com) by exploiting a vulnerability in the code that serves downloadable content from a project.

Exploiting this would have required the attacker to get a logged-in user to visit the malicious URL, which would have allowed the attacker to take control of the user's session with JavaScript (making requests to the API/site on behalf of the user). This URL would have looked something like hxxps[:]//readthedocs[.]org/projects/attacker-project/downloads/html/version-with-javascript-attack/.

Patches

This issue has been patched in our 8.8.1 release.
