GHSA-f38v-77qj-h4jq praisonai-platform 0.1.4 still boots on the hardcoded JWT secret dev-secret-change-me (default-open production guard)
Affected: praisonai-platform (PyPI) <= 0.1.4 — including 0.1.4, the version GHSA-3qg8-5g3r-79v5 declares as the patch; main HEAD 8acf77c531e624c46d3d61dcae37e9942e90972c is also affected. File src/praisonai-platform/praisonai_platform/services/auth_service.pyCWE: CWE-1188 (Insecure Default Initialization) + CWE-798 (Use of Hard-coded Credentials) -> CWE-287 (Improper Authentication)OverviewGHSA-3qg8-5g3r-79v5 (Critical) reported that praisonai-platform's JWT signing secret defaulted to the hardcoded literal "dev-secret-change-me", and that the production guard meant to prevent this was default-open (it only fired when PLATFORM_ENV != "dev", but PLATFORM_ENV defaults to "dev"). That advisory declares the issue patched in >= 0.1.4. **It is not.** The shipped praisonai-platform==0.1.4 (and current main) still resolves the signing key to "dev-secret-change-me" in any deployment that does not explicitly set PLATFORM_JWT_SECRET, because the 0.1.4 change merely duplicated the same default-open guard into a second function instead of failing closed. An unauthenticated attacker reads the literal from the public source, forges a JWT with an arbitrary sub, and is authenticated as that user — including a workspace owner.ImpactAny deployment that runs praisonai-platform 0.1.4 without explicitly exporting a strong PLATFORM_JWT_SECRET signs and verifies session JWTs with the publicly known key "dev-secret-change-me". The package's documented entry point — `python -m praisonai_platform --host 0.0.0.0 --port 8000` (equivalently `uvicorn praisonai_platform.api.app:app --host 0.0.0.0`) — sets neither PLATFORM_JWT_SECRET nor PLATFORM_ENV, so this is the default state, not an edge case. A repository-wide search finds both variables only at the two guard sites and in test fixtures; no shipped Dockerfile, compose file, or deployment doc sets either.Consequences:**Complete authentication bypass (unauthenticated).** Knowing only the public default secret read from source, an attacker mints HS256({"sub": <user id>, "email": …, "exp": <future>}, "dev-secret-change-me"). The platform's own verifier accepts it and returns an authenticated identity for the attacker-chosen sub — no account and no prior access required. This is the headline defect: the identical break GHSA-3qg8 was scored 9.8 for.**Workspace-owner takeover (when a target owner's id is known).** Forging the sub of a workspace owner satisfies require_workspace_member / require_workspace_owner and the owner-gated routes, yielding owner-level read/update/delete of every resource in that workspace plus member/role management. uuid4 user ids are unguessable, so impersonating a specific owner additionally requires learning that owner's id — which any co-member can read directly from GET /{workspace_id}/members (returns List[MemberResponse], each carrying user_id and role, to any holder of require_workspace_member), and which also surfaces in logs and referrals. The end state matches the three Critical advisories of the 0.1.4 wave (this one, plus GHSA-c2m8-4gcg-v22g 9.6 and GHSA-h8q5-cp56-rr65).**Resource destruction / lock-out (A:H).** Owner impersonation reaches DELETE /workspaces/{workspace_id} (gated by require_workspace_owner), which deletes the entire workspace and every contained resource, and DELETE /{workspace_id}/members/{user_id}, which evicts legitimate members — irrecoverable denial of the workspace to its rightful users.**Affected population:** every default (no PLATFORM_JWT_SECRET) deployment of 0.1.4 — the version users upgrade to specifically because GHSA-3qg8 told them 0.1.4 is fixed.PR:N / AC:L apply to the authentication-bypass primitive: minting a valid session for a known sub needs no account, only the public secret. Targeted takeover of a specific owner additionally requires that owner's user id (readable by any co-member from the member-list response above, or recoverable from logs / prior exposure); this conditions the highest-impact path but not the bypass itself. The vector matches the PR:N/9.8 GitHub assigned the original GHSA-3qg8 for the identical defect.Technical DetailsAll references are to src/praisonai-platform/praisonai_platform/... in praisonai-platform==0.1.4 (PyPI sdist) and main HEAD 8acf77c. The two copies of services/auth_service.py are byte-identical — sha256 = cc29d43c5412da2c73c818859b8d8b146587842999b777336017ab9d9e509258 for both the shipped 0.1.4 sdist and the HEAD checkout — so the patched release and current main carry the same defect verbatim.**1. Module-load guard is default-open (services/auth_service.py:25-34).**The raise fires only when PLATFORM_ENV != "dev". But os.environ.get("PLATFORM_ENV", "dev") defaults to "dev", and PLATFORM_ENV is set nowhere in the package or its deployment configuration (a repo-wide search finds PLATFORM_ENV only at these two guard sites, and PLATFORM_JWT_SECRET only here plus in tests/ fixtures that set it explicitly — no Dockerfile, compose file, or doc sets either). So in a clean deployment the predicate is True and ("dev" != "dev") = False; the guard does not fire and JWT_SECRET stays "dev-secret-change-me".**2. The 0.1.4 "fix" duplicated the same default-open guard (services/auth_service.py:114-128).** Instead of failing closed, 0.1.4 added the identical predicate to _issue_token:GHSA-3qg8 states the intended fix is to "fail-closed at import time when the secret is the default, regardless of any environment variable." HEAD does not do that; both guard copies remain gated on the PLATFORM_ENV != "dev" condition that is false by default. The advisory's own patch threshold (>= 0.1.4) is therefore incorrect — 0.1.4 is still vulnerable.**3. Verification trusts the forged sub end-to-end (services/auth_service.py:131-141 -> api/deps.py:28-73).**get_current_user (deps.py:28) returns this identity directly; require_workspace_member (deps.py:54) authorizes purely from member_svc.has_role(workspace_id, identity.id, min_role) against the forged sub. Decoding is otherwise sound (HS256 pinned, exp enforced by PyJWT, no verify=False), so the only break is the default secret. No middleware or app-factory check re-validates (api/app.py mounts the routers with per-route Depends(get_current_user) and no global re-root).The cross-workspace IDOR (GHSA-h8q5-cp56-rr65) and member-role privilege-escalation (GHSA-c2m8-4gcg-v22g) fixes were reviewed at HEAD and appear complete; this advisory is specific to the JWT-secret guard.Reproductionpraisonai-platform is a Python server package, so the PoC is a self-contained Python reproducer that installs the shipped 0.1.4 release, simulates a default deployment (no env vars), forges a token with the public default secret, and feeds it to the package's own AuthService._verify_token.End-to-end (runtime) verificationObserved output, run against the actually-installed praisonai-platform==0.1.4 (the GHSA-3qg8 "patched" release):This is the package's own _verify_token (not a re-implementation) returning an authenticated AuthIdentity for an attacker-chosen sub, proving end-to-end that 0.1.4 accepts forged sessions in a default deployment. The intermediate observation (the module-level JWT_SECRET equals the public default) and the final sink (the verifier returns the victim identity) were both observed at runtime.Default-open contrastSetting only PLATFORM_ENV (still no PLATFORM_JWT_SECRET) makes the same guard fire at import — demonstrating that the only thing protecting a production deployment is an environment variable that defaults to the unsafe value:The guard can fail closed — it simply does not in the default (PLATFORM_ENV unset → "dev") state, which is exactly what GHSA-3qg8 reported and 0.1.4 left unchanged.Suggested FixFail closed, independent of PLATFORM_ENV:Remove the _DEFAULT_SECRET fallback entirely (no default signing key), or at minimum raise unconditionally when the secret is the default — do **not** gate that check on PLATFORM_ENV, whose default value ("dev") is precisely what disables the check.Apply the same to the duplicated guard in _issue_token.Consider generating a random per-process secret only for an explicit, clearly-flagged dev mode (e.g. PLATFORM_ENV=dev opt-in), so the safe default is fail-closed.Disclosure Timeline2026-05-30: Discovered as an incomplete fix of GHSA-3qg8-5g3r-79v5 while auditing praisonai-platform at main HEAD 8acf77c.
