CVE-2026-101718: 
Oracle Agile PLM vulnerability analysis and mitigation

CVE-2026-101718 is an authentication bypass vulnerability in the Oracle Agile PLM Application Server component, affecting version 9.3.6 of Oracle Agile PLM within the Oracle Supply Chain product family. The vulnerability allows an unauthenticated attacker with network access via TLS to compromise the application through improper access controls. It was disclosed on October 20, 2026, as part of Oracle's Critical Patch Update (CPU) for October 2026. The CVSS v3.1 base score is 6.5 (Medium), reflecting high confidentiality impact and low integrity impact with no availability impact (Oracle CPU Oct 2026).

The vulnerability stems from improper access controls over TLS connections in the Oracle Agile PLM Application Server component, classified as an authentication bypass (CWE not explicitly assigned, but consistent with improper authentication or access control weaknesses). An unauthenticated attacker with network access via TLS can exploit this flaw without requiring any privileges or user interaction, though the attack complexity is rated High, indicating that specific conditions or configurations must be met for successful exploitation. The vulnerability enables unauthorized read access to critical PLM data and limited unauthorized write (update, insert, delete) operations on some accessible data (Oracle CPU Oct 2026). No public technical write-ups or proof-of-concept code have been identified at this time.

Successful exploitation can result in unauthorized access to all Oracle Agile PLM accessible data, representing a high confidentiality impact for organizations relying on this product lifecycle management platform to store sensitive product, engineering, and supply chain data. Additionally, attackers may perform unauthorized update, insert, or delete operations on some accessible data, resulting in a low integrity impact. There is no availability impact, and the scope is unchanged, meaning exploitation is confined to the Agile PLM application itself without direct lateral movement to other systems (Oracle CPU Oct 2026).

There is no evidence of public proof-of-concept exploit code or active in-the-wild exploitation of CVE-2026-101718 at this time. The EPSS score is reported as 0.0, indicating a very low current probability of exploitation (Oracle CPU Oct 2026). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The High attack complexity rating further reduces the likelihood of opportunistic exploitation, as specific preconditions must be satisfied.

Oracle has released a patch for CVE-2026-101718 as part of the October 2026 Critical Patch Update; organizations running Oracle Agile PLM version 9.3.6 should apply the patch immediately via the Oracle Supply Chain patch availability documentation (Oracle CPU Oct 2026). As a temporary workaround, Oracle recommends restricting network access to the Oracle Agile PLM Application Server to trusted networks only and monitoring for suspicious TLS connections and unauthorized data access attempts. Oracle strongly advises against relying on network-level mitigations as a long-term solution, as they do not address the underlying vulnerability.

The vulnerability was catalogued by AUSCERT (ASB-2026.0280) and tracked by VulDB (vuln/423453) shortly after Oracle's October 2026 CPU release, indicating routine security community monitoring. No notable researcher commentary, vendor statements beyond Oracle's advisory, or significant social media discussion has been identified for this specific CVE.
