BUG - @sap/ux-ui5-tooling reports multiple moderate vulnerabilities

[huulanka]

Description

Running npm install / npm audit in a consumer project that uses @sap/ux-ui5-tooling reports multiple moderate vulnerabilities due to a vulnerable js-yaml dependency pulled in transitively via the Open UX Tools packages. The recommended fix from npm audit would require a breaking upgrade of @sap/ux-ui5-tooling, which cannot be done safely by consumers on their own.

Steps to Reproduce

Steps to reproduce the behavior:

1. Create or open a CAP / UI5 project that uses @sap/ux-ui5-tooling as a devDependency (for example via SAP Fiori tools).
2. Run npm install in the project.
3. Run npm audit (or npm audit fix).
4. See the reported vulnerabilities for js-yaml and related @sap-ux/* packages coming from Open UX Tools.

Expected results

• npm audit should not report vulnerabilities originating from js-yaml in the Open UX Tools dependency tree.
• No need for consumers to run npm audit fix --force or perform breaking upgrades on their own to mitigate these issues.

Actual results

• npm install prints a deprecation warning for [email protected].
• npm audit reports 12 moderate vulnerabilities related to js-yaml < 4.1.1 (prototype pollution in merge (<<)), referenced via @sap-ux/ui5-config, @sap-ux/adp-tooling, @sap-ux/preview-middleware, @sap-ux/project-access, @sap-ux/odata-service-writer, @sap-ux/project-input-validator, @sap-ux/mockserver-config-writer, @sap-ux/fiori-generator-shared, and @sap-ux/telemetry.
• npm audit recommends npm audit fix --force, which would install a newer @sap/ux-ui5-tooling version (>= 1.19.1 / >= 1.19.3) and is flagged as a breaking change.

Version/Components/Environment

• Consumer project: CAP / UI5 project using @sap/[email protected] (as an example)
• Open UX Tools packages involved: @sap-ux/ui5-config, @sap-ux/adp-tooling, @sap-ux/preview-middleware, @sap-ux/project-access, @sap-ux/odata-service-writer, @sap-ux/project-input-validator, @sap-ux/mockserver-config-writer, @sap-ux/fiori-generator-shared, @sap-ux/telemetry
• OS:
  • [ ] Mac OS
  • [ ] Windows
  • [x] Other (Linux)

Additional context:

• npm audit output references advisory GHSA-mh29-5h37-fv8m for js-yaml.
• There is already a related PR in this repository: https://github.com/SAP/open-ux-tools/pull/3840

Upgrade is being worked on as it causes changes to the test snapshots with the yaml change.
