GHSA-wm8x-php5-hvq6 — maligned
GHSA-wm8x-php5-hvq6 is a security vulnerability in maligned. No vendor fix is recorded yet; mitigation options are listed below.
Maligned causes incorrect deallocation
Real-World Exposure
malignedReal-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
maligned::align_first manually allocates with an alignment larger than T, and then uses Vec::from_raw_parts on that allocation to get a Vec<T>.
GlobalAlloc::dealloc requires that the layout argument must be the same layout that was used to allocate that block of memory.
When deallocating, Box and Vec may not respect the specified alignment and can cause undefined behavior.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for maligned, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of maligned has shipped for GHSA-wm8x-php5-hvq6 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-wm8x-php5-hvq6 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-wm8x-php5-hvq6. 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-wm8x-php5-hvq6 in your dependencies?
O3 Security finds GHSA-wm8x-php5-hvq6 across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
