How do I mitigate GHSA-wm8x-php5-hvq6 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Real-World Exposure

1 pkg affected

🦀maligned

Real-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.
