Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
yudao-cloud before 2026.06 contains a broken access control vulnerability in the BPM module that allows any authenticated user to access arbitrary process instance records by supplying a caller-controlled process-instance identifier to an unprotected endpoint lacking the @PreAuthorize annotation. Attackers can query any process-instance identifier through the unguarded GET endpoint to read sensitive workflow data including submitted form variables, approver identities, approval and rejection comments, and process BPMN XML without ownership or tenant party verification.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-07-30.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

yudao-cloud 2026.06 or later

  1. 1. Identify the current yudao-cloud version in use by checking the project's pom.xml or build configuration
  2. 2. Backup the current database and application configuration
  3. 3. Update the yudao-cloud dependency version in pom.xml to 2026.06 or later (e.g., <version>2026.06</version>)
  4. 4. Rebuild the application with the updated dependencies (mvn clean package -DskipTests)
  5. 5. Deploy the rebuilt application to your environment
  6. 6. Verify the @PreAuthorize annotation is now present on the BPM process instance endpoint
  7. 7. Test that authorization checks properly enforce ownership/tenant isolation
Caveat Review release notes between your current version and 2026.06 for any breaking changes; minor version upgrades typically have minimal impact

Generated from the published advisory — verify against the referenced sources before acting.

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
