olm-sys: wrapped library unmaintained, potentially vulnerable
Blast Radius
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. 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.
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 pinpoints whether GHSA-p2q9-36vw-c468 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-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 detects GHSA-p2q9-36vw-c468 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.
