ERROR {org.wso2.carbon.apimgt.keymgt.events.APIMOAuthEventInterceptor} - Unable to add revoked JWT signature to the database

The cause for the issue is when generating a token with Refresh grant type and if the token persists in the OAuth cache as JWT, in the next token generation within the OAuth cache period, the relevant JWT signature cannot persist in the 'AM_REVOKED_JWT' table as it exceeds 'Signature' column length.

Steps to Reproduce

  1. Generate an access token and refresh token using any relevant grant type
  2. Generate a new access token using the previously generated refresh token(with the same consumer key/secret, scopes, and user as above)
  3. Generate a new access token within the OAuth cache period same as step 1(with the same consumer key/secret, scopes, and user as above)

Fixed in WSO2 API Manager 4.6.0

This issue has been fixed in WSO2 API Manager 4.6.0. The JWT signature database truncation error no longer occurs when using refresh tokens.

Issue Summary

In APIM 3.1.0, generating access tokens using the refresh grant type (within OAuth cache period) caused a database error:

Error in adding revoked jwt signature to database
Data truncation: Data too long for column 'SIGNATURE' at row 1

Problem: When refresh tokens were used to generate new access tokens, the old JWT signature needed to be stored in the AM_REVOKED_JWT table to mark it as revoked. However, the signature exceeded the SIGNATURE column length, causing the database truncation error.

Fix Details

Fix: PR #1864 in identity-inbound-auth-oauth repository (June 23, 2022)

Database Schema Update: The AM_REVOKED_JWT table now has sufficient column size:

CREATE TABLE AM_REVOKED_JWT (
    UUID VARCHAR(255) NOT NULL,
    SIGNATURE VARCHAR(2048) NOT NULL,  -- ← Increased to 2048 characters
    EXPIRY_TIMESTAMP BIGINT NOT NULL,
    TENANT_ID INTEGER DEFAULT -1,
    TOKEN_TYPE VARCHAR(15) DEFAULT 'DEFAULT',
    TIME_CREATED TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    PRIMARY KEY (UUID)
);

Testing

Test Scenario:

  1. Register DCR client with refresh_token grant
  2. Generate initial access token and refresh token (password grant)
  3. Use refresh token to generate new access token (1st refresh)
  4. Wait 2 seconds (stay within OAuth cache period)
  5. Use refresh token again to generate new access token (2nd refresh)
  6. Verify no database errors occur

Test Results:

Step 3: Using refresh token (1st refresh)
  Status Code: 200 ✓
  New Access Token generated successfully

Step 4: Using refresh token (2nd refresh within cache period)
  Status Code: 200 ✓
  New Access Token generated successfully

Result: ✅ FIXED

Both refresh token operations succeeded without any database truncation errors. The JWT signatures are properly stored in the AM_REVOKED_JWT table.

Verification

The fix ensures that:

  • ✅ JWT signatures can be stored in AM_REVOKED_JWT table without truncation
  • ✅ Refresh token grant works properly on subsequent refreshes
  • ✅ OAuth cache behavior functions correctly
  • ✅ No database errors when tokens are revoked and replaced

Conclusion

The issue with JWT signature database truncation has been fixed. The SIGNATURE column now accommodates JWT signatures up to 2048 characters, which is sufficient for standard JWT tokens.

Tested on: WSO2 API Manager 4.6.0 Status: ✅ Fixed Fix Date: June 23, 2022 (PR #1864 in identity-inbound-auth-oauth) Test Method: REST API - Tested refresh token grant with multiple refreshes
