prettytable-rs: Force cast a &Vec<T> to &[T] may lead to undefined behavior
Blast Radius
prettytable-rsReal-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
In function Table::as_ref, a reference of vector is force cast to slice. There are multiple problems here:
- To guarantee the size is correct, we have to first do
Vec::shrink_to_fit. The function requires a mutable reference, so we have to force cast from immutable to mutable, which is undefined behavior (UB). - Even if (1) is sound,
&Vec<T>and&[T]still might not have the same layout. Treating them equally may lead to undefinted behavior (UB).
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for prettytable-rs. 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 prettytable-rs to 0.10.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gfgm-chr3-x6px 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-gfgm-chr3-x6px 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-gfgm-chr3-x6px. 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-gfgm-chr3-x6px in your dependencies?
O3 detects GHSA-gfgm-chr3-x6px 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.
