Severity: unknown. Patch status: fix status unknown.
Affected: Apache Syncope
Ids: CVE-2026-113511

Apache Syncope vulnerable to delegated administration boundaries bypass for Realm update

## Steps
1. Search the repo, its CI and infra config for Apache Syncope. If present, report the version in use and whether it's affected.
2. Apache Syncope 4.1.x, 4.0.x, 3.0.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 Syncope 3.0 to 4.1 (3 lines) | not named in the CVE record | check the vendor advisory | 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.
