olm-sys: wrapped library unmaintained, potentially vulnerable
Real-World Exposure
olm-sysReal-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
After several cryptographic vulnerabilities in libolm were disclosed publicly, the Matrix Foundation has officially deprecated the library. olm-sys is a thin wrapper around libolm and is now deprecated and potentially vulnerable in kind.
Users of olm-sys and its higher-level abstraction, olm-rs, are highly encouraged to switch to vodozemac as soon as possible. It is the successor effort to libolm and is written in Rust.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for olm-sys, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of olm-sys has shipped for GHSA-p2q9-36vw-c468 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-p2q9-36vw-c468 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p2q9-36vw-c468. 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-p2q9-36vw-c468 in your dependencies?
O3 Security finds GHSA-p2q9-36vw-c468 across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
