There is a potential denial of service vulnerability present in ActiveRecord's PostgreSQL adapter. This has been assigned the CVE identifier CVE-2022-44566. Versions Affected: All. Not affected: None. ## Fixed Versions - 2.3.18.47 (Rails LTS, which is a paid service and not part of the rubygem) - 3.2.22.34 (Rails LTS, which is a paid service and not part of the rubygem) - 4.2.11.27 (Rails LTS, which is a paid service and not part of the rubygem) - 5.2.8.15 (Rails LTS, which is a paid service and not part of the rubygem) - 6.1.7.1 - 7.0.4.1 ## Impact In ActiveRecord < 7.0.4.1 and < 6.1.7.1, when a value outside the range for a 64bit signed integer is provided to the PostgreSQL connection adapter, it will treat the target column type as numeric. Comparing integer values against numeric values can result in a slow sequential scan resulting in potential Denial of Service. ## Releases The fixed releases are available at the normal locations. ## Workarounds Ensure that user supplied input which is provided to ActiveRecord clauses do not contain integers wider than a signed 64bit representation or floats. ## Patches To aid users who aren't able to upgrade immediately we have provided patches for the supported release series in accordance with our maintenance policy 1 regarding security issues. They are in git-am format and consist of a single changeset. 6-1-Added-integer-width-check-to-PostgreSQL-Quoting.patch - Patch for 6.1 series 7-0-Added-integer-width-check-to-PostgreSQL-Quoting.patch - Patch for 7.0 series
