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
GHSA-m7mq-85xj-9x33 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 379,145 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.

Description
The encryption key for token encryption has a weak default value 'Secre$t' when TOKEN_HASH_SECRET environment variable is not set.
Affected Code
const key = crypto
.createHash('sha256')
.update(process.env.TOKEN_HASH_SECRET || 'Secre$t')
.digest()
Evidence
The default value 'Secre$t' is hardcoded in the source code and is cryptographically weak. This key is used to encrypt user IDs and workspace IDs in JWT tokens.
Impact
Token forgery - attackers can decrypt and manipulate encrypted token metadata, potentially changing user IDs or workspace IDs to escalate privileges or access unauthorized data.
Recommendation
Require TOKEN_HASH_SECRET to be set as a strong random value in environment variables. Throw an error on startup if not configured. Use a minimum of 32 bytes of entropy.
Notes
The TOKEN_HASH_SECRET has a weak hardcoded default 'Secre$t' (lines 31-34 and 50-53). This secret is used to derive an AES-256-CBC encryption key for encrypting sensitive metadata (user ID and workspace ID) embedded in JWT tokens via encryptToken() called at line 394 of passport/index.ts. If TOKEN_HASH_SECRET is not configured, an attacker knowing the default can decrypt the 'meta' field in JWTs to extract user IDs and workspace IDs. While this alone doesn't grant access (the JWT signature is separate), it leaks internal identifiers that could aid other attacks. The .env.example shows '# TOKEN_HASH_SECRET='popcorn'' - another weak value, and it's commented out suggesting it's optional. The application should require this secret to be explicitly set with a strong random value.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for flowise, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update flowise to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m7mq-85xj-9x33 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 GHSA-m7mq-85xj-9x33 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-m7mq-85xj-9x33. 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-m7mq-85xj-9x33 in your dependencies?
O3 Security finds GHSA-m7mq-85xj-9x33 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
