Unauthenticated Sensitive Data Exposure in Oracle Agile PLM User and User Group

IdentifiersCVE-2026-21940CWE-200· Exposure of Sensitive Information…

CVE-2026-21940 is an easily exploitable vulnerability in Oracle Agile PLM, Oracle Supply Chain, specifically in the User and User Group component of supported version 9.3.6. The issue is remotely reachable over HTTP and does not require authentication or user interaction. Based on the available vendor description, successful exploitation allows an unauthenticated network attacker to compromise the confidentiality of Oracle Agile PLM data, resulting in unauthorized access to critical data or potentially complete access to all data accessible through the Oracle Agile PLM application. Specific vulnerable functions or code paths are not provided in the available source material.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

The vulnerability has high confidentiality impact. A successful attacker can obtain unauthorized access to critical data stored in or exposed by Oracle Agile PLM and may be able to access all data available to the application. The provided CVSS 3.1 vector indicates no integrity or availability impact was identified in the vendor advisory, but the data exposure may still constitute a significant compromise of business-sensitive PLM information.

Mitigation

If you can’t patch tonight, do this now.

Until the vendor patch can be applied, reduce exposure by restricting or blocking network access to the affected Oracle Agile PLM HTTP interface to only trusted administrative or application networks, and remove unnecessary access paths to the vulnerable service where feasible. Oracle’s general mitigation guidance also recommends limiting unnecessary privileges and testing any workaround in non-production first, as protocol blocking or access restrictions may affect application functionality. These measures are temporary risk reductions, not a substitute for patching.

Remediation

Patch, then assume compromise.

Apply the Oracle security patch for Oracle Agile PLM 9.3.6 that addresses CVE-2026-21940. Oracle’s Critical Patch Update guidance also recommends staying on actively supported product versions and upgrading unsupported deployments so security fixes can be applied. If relevant to the environment, ensure cumulative Oracle CPU patches are fully applied, including any patch bundles that supersede or also remediate this CVE.
