CVE-2026-60527 is an improper authorization flaw in the Oracle WebLogic Server Console component. Affected versions are 14.1.2.0.0 and 15.1.1.0.0 of Oracle Fusion Middleware. The vulnerability allows an unauthenticated attacker with local logon access to the infrastructure hosting WebLogic Server to compromise the server. Although the attack vector is local (AV:L), the attack complexity is low (AC:L), requires no privileges (PR:N), and needs no user interaction (UI:N). The scope is changed (S:C), meaning a compromise of WebLogic Server can impact additional products in the environment. Successful exploitation results in unauthorized access to critical data or complete access to all data accessible via WebLogic Server (C:H, I:N, A:N). The CVSS 3.1 base score is 7.1 (High) with vector CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N.
The root cause is an improper authorization check (CWE-285) in the Console component. The software does not correctly verify whether an actor is authorized to access a resource or perform an action. Because the attacker has local logon access, they can interact with the Console’s functionality in a way that bypasses authorization controls. The manipulation involves an unknown input that triggers the authorization bypass. The vulnerability is easily exploitable and does not require authentication or user interaction. The technical details are not publicly disclosed, and there is no known exploit available at this time. However, the attack technique is mapped to MITRE ATT&CK T1548.002 (Abuse Elevation Control Mechanism). The vulnerability was identified on July 8, 2026, and published on July 21, 2026. Oracle has released a Critical Patch Update (CPU) for July 2026 addressing this flaw. The EPSS score is 0.00162, indicating a low probability of exploitation in the wild. Organizations running affected versions should prioritize patching due to the high confidentiality impact and scope change.
DailyCVE Form:
Platform: ……. Oracle WebLogic Server
Version: …….. 14.1.2.0.0, 15.1.1.0.0

Prediction: ….. July 2026 CPU
What Undercode Say:
- Analytics: CVSS 7.1 (High) | EPSS 0.00162 | Exploit Price $0–$5k | CTI Interest 0.00
- Bash command to check WebLogic version:
grep -i "weblogic" /opt/oracle/middleware/wlserver/.product.properties
- Check for CVE-2026-60527 patch status via Oracle CPU:
./opatch lsinventory -oh /u01/app/oracle/middleware -patch_id 35891234
- Sample Python script to test local Console authorization bypass (conceptual):
import requests Localhost Console endpoint with crafted input r = requests.get("http://localhost:7001/console/login/LoginForm.jsp", params={"j_username": "admin", "j_password": ""}) if "Console" in r.text: print("[!] Possibly vulnerable to CVE-2026-60527")
Exploit:
- No public exploit available.
- Attack requires local logon access to the infrastructure.
- Attacker can abuse the Console’s improper authorization to read sensitive files (e.g.,
config.xml,SerializedSystemIni.dat) and extract datasource credentials. - Potential to deploy a WebShell or backdoor via the management console after gaining unauthorized access.
- Proof-of-concept would involve crafting HTTP requests to the Console that bypass authorization checks using manipulated parameters or session tokens.
Protection:
- Apply Oracle’s July 2026 Critical Patch Update (CPU) immediately.
- Restrict local logon access to the WebLogic Server infrastructure to trusted users only.
- Enable WebLogic’s security framework and enforce strict role-based access controls (RBAC) for the Console.
- Monitor Console access logs for unusual patterns (e.g., unauthorized file reads, abnormal login attempts).
- Use network segmentation to limit who can reach the WebLogic Server’s administrative interfaces.
- Consider deploying a Web Application Firewall (WAF) in front of the Console to filter malicious requests.
Impact:
- Confidentiality: High – unauthorized access to critical data or complete access to all WebLogic Server accessible data.
- Integrity: None – the vulnerability does not allow data modification.
- Availability: None – no denial-of-service impact.
- Scope Change: Yes – attacks can significantly impact additional products in the environment.
- Business Risk: High for organizations using WebLogic Server to store sensitive customer data, financial records, or intellectual property. Data breaches can lead to regulatory fines, reputational damage, and operational disruption.
