## Summary

An unauthenticated attacker can exploit a cross-site scripting flaw in SAP NetWeaver Visual Composer by sending a crafted malicious link, which runs script in the browser of a victim who clicks it, with low impact to confidentiality and integrity. The bug is reached remotely over the network, but it requires the victim to click the link.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- SAP\_SE SAP NetWeaver Visual Composer: VC70RUNTIME 7.50

## Description

SAP NetWeaver Visual Composer does not perform sufficient input validation and output encoding on certain request data. An unauthenticated attacker could craft a malicious link containing specially crafted input. If a victim clicks the link, the injected script executes in the victim's browser within the context of the affected application. This results in a low impact on confidentiality and integrity. There is no impact on availability.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-120016 (Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Visual Composer), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-120016 (entry last updated 2026-11-10):
Affected:
- SAP_SE SAP NetWeaver Visual Composer: versions VC70RUNTIME 7.50
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-120016 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-120016 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- https://me.sap.com/notes/3806484
- https://url.sap/sapsecuritypatchday
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
