How severe is GHSA-c65f-x25w-62jv?

No CVSS score has been assigned to GHSA-c65f-x25w-62jv yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-c65f-x25w-62jv?

GHSA-c65f-x25w-62jv affects the following packages: openssl-encrypt (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-c65f-x25w-62jv?

Update openssl-encrypt to 1.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c65f-x25w-62jv is resolved across your whole dependency graph.

How do I detect GHSA-c65f-x25w-62jv in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openssl-encrypt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-c65f-x25w-62jv if there is no patch (or I can't update yet)?

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.

Is GHSA-c65f-x25w-62jv actively exploited in the wild?

No public exploit code has been indexed for GHSA-c65f-x25w-62jv yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-c65f-x25w-62jv?

GHSA-c65f-x25w-62jv has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 30th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-c65f-x25w-62jv?

GHSA-c65f-x25w-62jv is classified as CWE-942 (CWE-942). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

1 pkg affected

🐍openssl-encrypt

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Summary

Both standalone servers configure CORS with allow_origins=["*"], allow_credentials=True, allow_methods=["*"], and allow_headers=["*"].

Affected Code

# server/key-server/app/main.py:86-92
# server/telemetry-server/app/main.py:23-29
app.add_middleware(
    CORSMiddleware,
    allow_origins=settings.cors_origins,  # defaults to ["*"]
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

The docker-compose file (openssl_encrypt_server/docker-compose.yml:75) also defaults CORS_ORIGINS to *, and .env.example ships with CORS_ORIGINS=*.

Impact

This is the most permissive CORS configuration possible, allowing any website to make fully credentialed cross-origin requests to the API. An attacker's website could make authenticated API calls on behalf of any user who visits it.

Recommended Fix

Remove wildcard defaults — require explicit origin configuration
Never combine allow_origins=["*"] with allow_credentials=True
Update .env.example with placeholder domains instead of *

Fix

Fixed in commit 809416b on branch releases/1.4.x — changed CORS default from ["*"] to [] in both key-server and telemetry-server; added validation rejecting wildcard when debug=False.
