Missing Cryptographic Step in cassproject
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.
How urgent is this, really
CVE-2022-29229 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,636 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
cassprojectnpmDescription
Impact
CaSS Library, (npm:cassproject) has a missing cryptographic step when storing cryptographic keys that can allow a server administrator access to an account’s cryptographic keys. This affects CaSS servers using standalone username/password authentication, which uses a method that expects e2e cryptographic security of authorization credentials.
Patches
The issue has been patched in 1.5.8, however, the vulnerable accounts are only resecured when the user next logs in using standalone authentication, as the data required to resecure the account is not available to the server.
Workarounds
The issue may be mitigated by using SSO or client side certificates to log in. Please note that SSO and client side certificate authentication does not have this expectation of no-knowledge credential access, and cryptographic keys are available to the server administrator.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cassproject, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update cassproject to 1.5.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-29229 is resolved across your whole dependency graph.
Workarounds
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 CVE-2022-29229 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2022-29229. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-29229 in your dependencies?
O3 Security finds CVE-2022-29229 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
