Description
Summary
This is a patch bypass of CVE-2025-58179 in commit 9ecf359. The fix blocks http://, https:// and //, but can be bypassed using backslashes (\) - the endpoint still issues a server-side fetch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for astro. 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.
Fix
Update astro to 5.13.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qcpr-679q-rhm2 is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-qcpr-679q-rhm2 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-qcpr-679q-rhm2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-qcpr-679q-rhm2 in your dependencies?
O3 detects GHSA-qcpr-679q-rhm2 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
