AI Analysis
Technical Summary
Backstage versions prior to 0.6.11 of the @backstage/plugin-catalog-backend-module-unprocessed contain an authorization bypass vulnerability (CWE-863). The unprocessed entities read endpoints fail to enforce permission checks, enabling any authenticated user to retrieve unprocessed entity data without proper authorization. This leads to unauthorized information disclosure. The vulnerability is fixed in @backstage/plugin-catalog-backend-module-unprocessed version 0.6.11, as well as in @backstage/plugin-catalog-unprocessed-entities-common version 0.0.15 and @backstage/plugin-catalog-unprocessed-entities version 0.2.30.
Potential Impact
An attacker with valid authentication can access unprocessed entity records that they should not be authorized to view. This results in unauthorized disclosure of potentially sensitive information. There is no impact on integrity or availability reported. No known exploits in the wild have been documented.
Mitigation Recommendations
Upgrade affected Backstage modules to the fixed versions: @backstage/plugin-catalog-backend-module-unprocessed version 0.6.11 or later, @backstage/plugin-catalog-unprocessed-entities-common version 0.0.15 or later, and @backstage/plugin-catalog-unprocessed-entities version 0.2.30 or later. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory information.
