··· 1 - # Bluesky PDS OAuth Provider Clock Tolerance Bug Report 2 - 3 - **Status:** Confirmed Bug 4 - **Severity:** High (blocks OAuth authentication) 5 - **Affects:** `@atproto/oauth-provider@0.13.4` (and likely earlier versions) 6 - **Date Identified:** 2025-11-18 7 - **Reported By:** ATCR Project 8 - 9 - --- 10 - 11 - ## Executive Summary 12 - 13 - The Bluesky PDS OAuth provider (`@atproto/oauth-provider`) incorrectly rejects valid client assertion JWTs when the client's system clock is even milliseconds ahead of the PDS server clock. This occurs because the `jose` library's `jwtVerify` function is called with `maxTokenAge` (which triggers `iat` validation) but without setting `clockTolerance`, causing it to default to 0 seconds. 14 - 15 - **Impact:** OAuth authentication fails for any client with normal clock drift ahead of the PDS, violating the ATProto OAuth specification and industry standards (FAPI 2.0, RFC 9068). 16 - 17 - **Fix:** Add `clockTolerance: 30` (or 60) parameter to the `jwtVerify` call in `client.ts`. 18 - 19 - --- 20 - 21 - ## Problem Description 22 - 23 - ### Observed Behavior 24 - 25 - OAuth client assertion validation fails with the error: 26 - 27 - ``` 28 - InvalidClientError: Validation of "client_assertion" failed: "iat" claim timestamp check failed (it should be in the past) 29 - ``` 30 - 31 - This occurs even when: 32 - - Both systems have proper NTP synchronization 33 - - Clock drift is minimal (observed: 115 milliseconds) 34 - - The drift is well within industry-standard tolerances (30-60 seconds) 35 - 36 - ### Root Cause 37 - 38 - **File:** `packages/oauth/oauth-provider/src/client/client.ts` 39 - **Line:** ~240 (in `authenticate` method) 40 - 41 - ```typescript 42 - const result = await this.jwtVerify<{ 43 - jti: string 44 - exp?: number 45 - }>(input.client_assertion, { 46 - subject: this.id, 47 - audience: checks.authorizationServerIdentifier, 48 - requiredClaims: ['jti'], 49 - maxTokenAge: CLIENT_ASSERTION_MAX_AGE / 1000, 50 - // Missing: clockTolerance parameter 51 - }) 52 - ``` 53 - 54 - **The Issue:** 55 - 56 - 1. `maxTokenAge` is set, which triggers `iat` (Issued At) claim validation in the `jose` library 57 - 2. `clockTolerance` is **not set**, so `jose` defaults to `0 seconds` 58 - 3. Any client clock drift ahead of the PDS (even 1ms) causes rejection 59 - 4.

ATProto OAuth Specification 137 - 138 - **Quote from https://atproto.com/specs/oauth:** 139 - 140 - > "Authorization Servers **should not reject client assertion JWTs generated less than a minute ago**" 141 - 142 - **Interpretation:** The PDS should accept client assertions with `iat` timestamps within ~60 seconds (past or future) to account for clock skew. 143 - 144 - **Current behavior:** Rejects any `iat` in the future, even by 1 millisecond. 145 - 146 - **Verdict:** ❌ **VIOLATES ATProto spec** 147 - 148 - --- 149 - 150 - ### 2. FAPI 2.0 Security Profile (Financial-grade API) 151 - 152 - **Quote from FAPI 2.0 spec:** 153 - 154 - > "Authorization servers **MUST accept** JWTs with an `iat` or `nbf` timestamp between 0 and **10 seconds in the future**" 155 - 156 - > "Authorization servers **SHALL reject** JWTs with an `iat` or `nbf` timestamp greater than **60 seconds in the future**" 157 - 158 - **Rationale from spec:** 159 - > "Even a few hundred milliseconds can cause rejection with clock skew... 10 seconds chosen to not affect security while increasing interoperability... Some ecosystems need 30 seconds to fully eliminate issues" 160 - 161 - **Current behavior:** Rejects tokens 115ms in the future. 162 - 163 - **Verdict:** ❌ **VIOLATES FAPI 2.0 minimum requirement (10s tolerance)** 164 - 165 - --- 166 - 167 - ### 3.

Set up two servers with independent NTP synchronization 308 - 2. Ensure Server A's clock is 100-500ms ahead of Server B 309 - 3. Configure OAuth client on Server A to authenticate against PDS on Server B 310 - 4. Attempt client assertion-based OAuth flow 311 - 5. Observe validation failure with `iat` error 312 - 313 - ### Verification After Fix 314 - 315 - 1. Apply the proposed code change (add `clockTolerance: 30`) 316 - 2. Rebuild and deploy PDS 317 - 3. Retry OAuth flow from Step 3 above 318 - 4. Confirm successful authentication 319 - 320 - ### Test Cases 321 - 322 - **Should ACCEPT (with 30s tolerance):** 323 - - ✅ `iat` 115ms in the future (observed case) 324 - - ✅ `iat` 5 seconds in the future 325 - - ✅ `iat` 29 seconds in the future 326 - - ✅ `iat` exactly 30 seconds in the future 327 - - ✅ `iat` 1 second in the past 328 - - ✅ `iat` 5 minutes in the past (within `maxTokenAge`) 329 - 330 - **Should REJECT:** 331 - - ❌ `iat` 31 seconds in the future 332 - - ❌ `iat` more than `maxTokenAge` seconds in the past 333 - - ❌ Invalid JWT signature 334 - - ❌ Missing required claims 335 - 336 - --- 337 - 338 - ## Impact Assessment 339 - 340 - ### Severity: HIGH 341 - 342 - **User impact:** 343 - - OAuth authentication fails intermittently based on clock variance 344 - - Affects any OAuth client whose clock is ahead of PDS 345 - - Unpredictable failures (works sometimes, fails other times) 346 - - Poor developer experience (confusing error message) 347 - 348 - **Affected scenarios:** 349 - - Docker/Podman registries authenticating to ATCR 350 - - Third-party OAuth clients (tangled.org works only because clock is behind) 351 - - Distributed systems with independent time synchronization 352 - - Cloud environments with clock drift (VMs, containers) 353 - 354 - **Current workarounds:** 355 - 1. Ensure OAuth client clock is always behind PDS (impractical) 356 - 2. Fork indigo library to send older `iat` timestamps (client-side hack) 357 - 3. Patch PDS with custom Docker image (deployment complexity) 358 - 359 - **None of these are acceptable long-term solutions.** 360 - 361 - --- 362 - 363 - ## Recommended Actions 364 - 365 - ### Immediate (Bluesky Team) 366 - 367 - 1. **Apply the one-line fix** to `oauth-provider/src/client/client.ts` 368 - 2. **Add `clockTolerance: 30`** to the `jwtVerify` call 369 - 3. **Publish new version** of `@atproto/oauth-provider` package 370 - 4. **Update PDS** to use fixed version 371 - 372 - ### Short-term (Bluesky Team) 373 - 374 - 1. **Add configuration option** for `clockTolerance` (allow deployments to adjust) 375 - 2. **Document the setting** in PDS configuration docs 376 - 3. **Add logging** to track clock skew patterns (for monitoring) 377 - 378 - ### Long-term (Bluesky Team) 379 - 380 - 1. **Add comprehensive time validation tests** covering clock skew scenarios 381 - 2. **Document OAuth timing requirements** in ATProto spec 382 - 3. **Consider** implementing server-provided nonces (DPoP pattern) for stricter validation without clock dependency 383 - 384 - ### For ATCR Project 385 - 386 - **Until upstream fix:** 387 - 1. Document this issue in ATCR troubleshooting guide 388 - 2. Implement client-side workaround (fork indigo with `-1s` offset in `iat`) 389 - 3. Monitor for PDS updates with the fix 390 - 391 - **After upstream fix:** 392 - 1. Update to fixed PDS version 393 - 2. Remove client-side workaround 394 - 3.

This violates the ATProto OAuth specification, FAPI 2.0 requirements, and industry best practices. 523 - 524 - The fix is trivial (one line of code), has no security downsides, and will improve interoperability for all OAuth clients authenticating to Bluesky PDS instances. 525 - 526 - **Recommended action:** Add `clockTolerance: 30` to the `jwtVerify` call in `oauth-provider/src/client/client.ts`. 527 - 528 - --- 529 - 530 - **Report Version:** 1.0 531 - **Last Updated:** 2025-11-18 532 - **Contact:** ATCR Project Team
