CVE-2026-60339 is a low‑severity information disclosure vulnerability affecting the Oracle Project Manufacturing module within Oracle E‑Business Suite. The flaw resides in the PJM Command Center component, a web‑based interface used for managing manufacturing projects, work orders, and inventory across distributed production environments. The vulnerability stems from improper access controls or insufficient input validation when handling certain HTTP requests—the exact manipulation vector is not publicly documented, but the issue is classified under CWE‑200 (Exposure of Sensitive Information to an Unauthorized Actor).
An attacker exploiting this vulnerability must meet several conditions. First, they require a low‑privileged account on the Oracle E‑Business Suite instance—this could be a standard user with limited permissions, such as a project viewer or a junior planner. Second, the attack is network‑based and carried out over HTTP, meaning the attacker can send maliciously crafted requests to the PJM Command Center endpoint without needing physical or local access. Third, the vulnerability is rated as “difficult to exploit” due to the high attack complexity (AC:H) — the attacker likely needs to chain multiple steps, guess specific parameters, or time the requests to bypass internal checks.
Once successfully exploited, the vulnerability permits unauthorized read access to a subset of Oracle Project Manufacturing data. The exposed information is not fully defined in public advisories, but given the component’s role, it could include project names, work order details, material requirements, supplier information, or production schedules. Importantly, the flaw does not allow data modification, deletion, or privilege escalation—its impact is strictly limited to confidentiality, and only for a partial data set.
The CVSS 3.1 base score is 3.1 (Low), with the vector AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N. The attack requires no user interaction, and the scope is unchanged, meaning the breach does not extend to other Oracle components. The EPSS score is 0.0023 (0.23%), indicating a very low probability of active exploitation in the wild. As of July 2026, no public exploit code or technical proof‑of‑concept has been released, and the vulnerability is not known to be leveraged by ransomware groups or advanced persistent threat actors.
This CVE was published on July 21, 2026, and is part of Oracle’s July 2026 Critical Patch Update (CPU), which delivered a record 1,449 patches across 1,235 CVEs. Oracle E‑Business Suite received the highest number of patches (410) in this CPU, underscoring the product family’s broad attack surface. Administrators are strongly advised to apply the official patch as soon as possible, as the vulnerability can be exploited remotely by any authenticated user with network access—making it a potential vector for insider threats or compromised low‑privileged accounts.

- Affected Installations: All Oracle Project Manufacturing deployments running version 16 with the PJM Command Center enabled.
Bash Commands & Codes
Check if your Oracle E‑Business Suite instance is running the vulnerable PJM Command Center component:
Connect to the Oracle EBS database and query for the PJM module version sqlplus apps/apps_password@ebs_db <<EOF SELECT component_name, version FROM fnd_product_installations WHERE component_name LIKE '%Project Manufacturing%'; EOF
Simulate a low‑privileged HTTP request to the PJM Command Center endpoint (for detection purposes only – do not use offensively):
Replace TARGET_IP and SESSION_TOKEN with actual values curl -X GET "http://TARGET_IP:8000/pjm/commandCenter?action=getProjectDetails&id=123" \ -H "Cookie: session=SESSION_TOKEN" \ -H "User-Agent: Mozilla/5.0" \ -v
Monitor access logs for anomalous patterns indicative of attempted exploitation:
Search for repeated GET requests to PJM endpoints from a single low‑privileged user
grep "GET /pjm/commandCenter" /u01/app/oracle/admin/ebs/logs/access_log.log \
| awk '{print $1, $7}' | sort | uniq -c | sort -nr
Check if the official Oracle patch (CPU July 2026) has been applied:
Run Oracle's opatch utility to list installed patches $ORACLE_HOME/OPatch/opatch lsinventory | grep -i "july 2026"
Exploit
As of the latest NVD and VulDB entries, no public exploit code or detailed technical write‑up exists for CVE‑2026‑60339. The vulnerability is considered “difficult to exploit” (attack complexity high), meaning that even if an attacker has a low‑privileged account, they must craft specific HTTP requests that bypass internal authorization checks—likely by manipulating parameters, session tokens, or URL paths in a way that the PJM Command Center fails to validate properly.
The attack vector is entirely remote over HTTP, so an adversary can launch the exploit from anywhere on the network. Successful exploitation grants read‑only access to a subset of Project Manufacturing data—the exact scope is not defined, but it may include project identifiers, work order statuses, material lists, or supplier names. Because the CVSS impact is limited to confidentiality (C:L) with no integrity or availability impact, this flaw cannot be used to modify, delete, or encrypt data, nor to escalate privileges.
Given the low severity and the absence of a public exploit, the current risk of active exploitation is minimal. However, insider threats or attackers who have already compromised a low‑privileged account could use this vulnerability to quietly gather intelligence about manufacturing operations, potentially aiding in subsequent social engineering or supply‑chain attacks.
Protection
– Apply the Official Patch: Oracle released a fix for CVE‑2026‑60339 as part of the July 2026 Critical Patch Update. Administrators should download and apply the relevant patch from Oracle Support (Patch ID available in the CPU advisory). This is the only complete mitigation.
– Restrict Network Access: Limit access to the PJM Command Center endpoint to only trusted IP ranges or internal networks. Use firewall rules or Oracle’s built‑in access control lists (ACLs) to block external HTTP requests to `/pjm/commandCenter` and related paths.
– Enforce Principle of Least Privilege: Review and reduce the permissions of low‑privileged users. Ensure that only personnel with a genuine business need can access the Project Manufacturing module. Disable or delete any unused accounts.
– Enable Comprehensive Logging: Activate detailed audit logging for all PJM Command Center interactions. Monitor logs for repeated, unusual, or out‑of‑pattern GET requests that might indicate reconnaissance or attempted exploitation.
– Web Application Firewall (WAF): Deploy a WAF in front of the Oracle E‑Business Suite to filter and block malicious HTTP requests targeting the PJM component. Create custom rules to detect and drop requests with suspicious parameters or unexpected payloads.
– Regular Vulnerability Scanning: Use authenticated vulnerability scanners (e.g., Qualys, Tenable) to detect missing patches and misconfigurations in the Oracle EBS environment. Schedule scans after each CPU release.
Impact
– Confidentiality: Unauthorized read access to a subset of Oracle Project Manufacturing data. This may expose sensitive project plans, work orders, material requirements, supplier details, or production schedules. The breach does not extend to other modules or the underlying database.
– Integrity: No impact – the vulnerability does not allow modification, deletion, or creation of any data.
– Availability: No impact – the flaw cannot cause denial of service or disrupt normal system operations.
– Privilege Escalation: None – the attacker remains at their original low‑privilege level.
– Business Consequence: While the CVSS score is low, the exposure of manufacturing intelligence could be leveraged for competitive intelligence, social engineering, or supply‑chain reconnaissance. In regulated industries (e.g., defense, aerospace), even partial data leaks may trigger compliance violations.
– Exploitability: Difficult (AC:H) – requires a low‑privileged account and crafted HTTP requests. No public exploit exists, and the attack complexity reduces the likelihood of widespread exploitation.
– Patch Timeline: Oracle included the fix in the July 2026 CPU; administrators should apply the patch by mid‑August 2026 to close the window of exposure. Given the low severity, many organizations may prioritize higher‑risk CVEs first, but delaying beyond 30–60 days increases the risk as reverse‑engineering of the patch could lead to the development of a working exploit.
