abomonation transmutes &T to and from &[u8] without sufficient constraints
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
abomonationReal-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
This transmute is at the core of the abomonation crates. It's so easy to use it to violate alignment requirements that no test in the crate's test suite passes under miri.
The use of this transmute in serialization/deserialization also incorrectly assumes that the layout of a repr(Rust) type is stable. This transmute can also disclose both the contents of padding bytes which may be an information leak and the contents of pointers, which may be used to defeat ASLR.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for abomonation, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of abomonation has shipped for GHSA-hfxp-p695-629x 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-hfxp-p695-629x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-hfxp-p695-629x. 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-hfxp-p695-629x in your dependencies?
O3 Security finds GHSA-hfxp-p695-629x across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
