Which packages are affected by GHSA-xgfm-fjx6-62mj?

GHSA-xgfm-fjx6-62mj affects the following packages: readthedocs-sphinx-search (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-xgfm-fjx6-62mj?

Update readthedocs-sphinx-search to 0.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xgfm-fjx6-62mj is resolved across your whole dependency graph.

How do I detect GHSA-xgfm-fjx6-62mj in my PyPI dependencies?

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

How do I mitigate GHSA-xgfm-fjx6-62mj 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.

How does O3 Security protect against GHSA-xgfm-fjx6-62mj?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-xgfm-fjx6-62mj can be triaged on real exposure rather than presence alone.

Description

Impact

This vulnerability could have allowed an attacker to include arbitrary HTML content in search results by having a user search a malicious project. This was due to our search client not correctly escaping all user content from search results. You can find more information in the advisory published in our readthedocs.org repo.

Users of this extension should update to the 0.3.2 version, and trigger a new build.

This issue was discovered by a member of our team, and we have seen no signs that this vulnerability was exploited in the wild.

Patches

This issue has been patched in our 0.3.2 version.
