GHSA-pfp7-vxgr-83pw
toodee is vulnerable to Heap Buffer Overflow through its DrainCol Destructor
Blast Radius
toodeeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
An off-by-one error in the DrainCol::drop destructor could cause an unsafe memory copy operation to exceed the bounds of the associated vector.
The error was related to the size of the data being copied in one of the ptr::copy invocations inside the destructor.
When removing the first column from a TooDee object, the DrainCol return object could cause a heap buffer overflow vulnerability when it is dropped.
The issue was fixed in commit e6e16d5 by reducing the copied size by one.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for toodee. 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 toodee to 0.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pfp7-vxgr-83pw 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-pfp7-vxgr-83pw 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-pfp7-vxgr-83pw. 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-pfp7-vxgr-83pw in your dependencies?
O3 detects GHSA-pfp7-vxgr-83pw across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
