Invalid URL generation in bitlyshortener
Blast Radius
bitlyshortenerReal-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
Impact
Due to a sudden upstream breaking change by Bitly, versions of bitlyshortener <0.6.0 generate invalid short URLs. All users are affected and must update immediately.
Patches
Upgrading bitlyshortener to 0.6.0 or newer will prevent the generation such invalid short URLs.
Workarounds
A workaround is to replace "https://j.mp/" in each generated short URL with "https://bit.ly/".

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bitlyshortener. 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 bitlyshortener to 0.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rcrv-228c-gprj 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-rcrv-228c-gprj 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-rcrv-228c-gprj. 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-rcrv-228c-gprj in your dependencies?
O3 detects GHSA-rcrv-228c-gprj across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
