GHSA-9g3v-v24q-jj5p
HIGHGHSA-9g3v-v24q-jj5p is a high-severity (CVSS 7.3) CWE-770 vulnerability in rdiffweb. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-9g3v-v24q-jj5p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
rdiffweb does not have a rate limit on incorrect password attempts to prevent brute force attacks
Blast Radius
rdiffwebReal-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
rdiffweb prior to 2.5.0a4 does not have a rate limit to prevent attackers attempting brute force attacks to guess passwords. Version 2.5.0a4 limits the number of incorrect password attempts.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rdiffweb. 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 rdiffweb to 2.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9g3v-v24q-jj5p 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-9g3v-v24q-jj5p 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-9g3v-v24q-jj5p. 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-9g3v-v24q-jj5p in your dependencies?
O3 detects GHSA-9g3v-v24q-jj5p across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
