CVE-2026-82348Network attack vectorHinoki check available

Cross-weblog resource tampering via unscoped ID lookups

Published Sep 28, 2026 · Updated Sep 28, 2026

Authorization bypass in Apache Roller 6.1.5 allows remote authenticated users to read, modify, or delete another weblog's resources. Authoring actions resolve request-supplied resource IDs without checking that the resources belong to the action's weblog. Authoring rights on one weblog suffice; a weblog administrator can also overwrite another weblog's Velocity template, which is evaluated when that weblog renders.
