Which packages are affected by GHSA-hpj7-wq8m-9hgp?

GHSA-hpj7-wq8m-9hgp affects the following packages: aiohttp (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-hpj7-wq8m-9hgp?

Update aiohttp to 3.14.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hpj7-wq8m-9hgp is resolved across your whole dependency graph.

How do I detect GHSA-hpj7-wq8m-9hgp in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for aiohttp. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-hpj7-wq8m-9hgp 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-hpj7-wq8m-9hgp?

O3 pinpoints whether GHSA-hpj7-wq8m-9hgp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-hpj7-wq8m-9hgp actively exploited in the wild?

No public exploit code has been indexed for GHSA-hpj7-wq8m-9hgp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Summary

DigestAuthMiddleware can send an authentication response after following a cross-origin redirect.

Impact

If the client follows a redirect (the default option) to an attacker controlled domain, the attacker may be able to extract the auth digest.

This likely requires an open redirect vulnerability or similar on the target domain for an attacker to be able to execute. Further, the attacker is only receiving the digest, so should only be able to extract the user's credentials if the cryptography is weak or there is some kind of password reuse.

Workaround

Disable follow_redirects if this is a concern.
