Who should care

Defenders responsible for Apache Roller deployments should assess exposure and prioritize upgrading to Apache Roller 6.1.6 or later. They should also review compensating controls for exposed systems, monitor for suspicious template authoring activity, and verify the integrity of weblog administrator access and template authoring activity.

Why it matters

CVE-2026-82385 allows weblog administrators to read sensitive files on the application classpath, potentially exposing secrets and configuration data. Defenders should prioritize upgrading to Apache Roller 6.1.6 or later and monitor for suspicious template authoring activity.

• Potential exposure of sensitive information, including Roller configuration files containing secrets
• Verification of weblog administrator access and template authoring activity
• Possible data breaches due to unintended information disclosure

Technical summary

CVE-2026-82385 is an Exposure of Sensitive Information vulnerability in Apache Roller 6.1.5. A weblog administrator can read files on the application classpath by authoring a Velocity template that uses an include directive to load a classpath resource outside the theme namespace. This allows potential exposure of sensitive information, including Roller configuration files containing secrets. The vulnerability affects any weblog whose administrator can author templates, and users are recommended to upgrade to Apache Roller 6.1.6 or later.

Defensive priority
