CVE-2024-7340
HIGHCVE-2024-7340 is a high-severity (CVSS 8.8) Path Traversal vulnerability in weave. O3 Security confirms whether CVE-2024-7340 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
W&B Weave server remote arbitrary file leak and privilege escalation
Blast Radius
weaveReal-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
The Weave server API allows remote users to fetch files from a specific directory, but due to a lack of input validation, it is possible to traverse and leak arbitrary files remotely. In various common scenarios, this allows a low-privileged user to assume the role of the server admin.
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 weave. 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 weave to 0.50.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-7340 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 CVE-2024-7340 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 CVE-2024-7340. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-7340 in your dependencies?
O3 detects CVE-2024-7340 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
