Apache Software Foundation Apache Roller: remote code execution

Apache Software Foundation Apache Roller

Deserialization of Untrusted Data in Apache Roller 6.1.5 allows an unauthenticated remote attacker to cause deserialization of attacker-controlled bytes, because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication.

## Apache Software Foundation Apache Roller: remote code execution
Severity: critical. Patch status: fix status unknown.
Affected: Apache Software Foundation Apache Roller
Ids: CVE-2026-82384

Deserialization of Untrusted Data in Apache Roller 6.1.5 allows an unauthenticated remote attacker to cause deserialization of attacker-controlled bytes, because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication.

## Steps
1. Search the repo, its CI and infra config for Apache Software Foundation Apache Roller. If present, report the version in use and whether it's affected.
2. Apache Roller 6.1.x: the CVE record names no fix; check the vendor advisory before assuming there is none. Until one ships: restrict network access to it.

## Fix by release line
| Line | State | Fix | Until then |
|---|---|---|---|
| Apache Roller 6.1.x | not named in the CVE record | check the vendor advisory: https://github.com/apache/roller/pull/171 | restrict network access to it |

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
