CVE-2026-35305: Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Coherence. While the vulnerability is in Oracle Coherence, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Coherence accessible data as well as unauthorized update, insert or delete access to some of Oracle Coherence ac
CVE-2026-35305 is a critical vulnerability in Oracle Coherence 15.1.1.0.0 that allows an unauthenticated attacker with network access via HTTP to compromise the product. Exploitation can lead to unauthorized access to critical data, including the ability to read, update, insert, or delete data accessible by Oracle Coherence. The vulnerability has a CVSS 3.1 base score of 9.3, indicating high confidentiality and integrity impact with no required privileges or user interaction. Oracle has released a Critical Security Patch Update in June 2026 addressing this and other vulnerabilities, strongly recommending patch application. Until patched, risk reduction may be possible by blocking relevant network protocols or limiting privileges, though these may affect functionality.
AI Analysis
Technical Summary
This vulnerability affects Oracle Coherence version 15.1.1.0.0 and is exploitable remotely without authentication via HTTP. Successful exploitation can result in unauthorized access and modification of data managed by Oracle Coherence, potentially impacting additional Oracle products due to scope change. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N) reflects network attack vector, low attack complexity, no privileges or user interaction required, with a scope change and high confidentiality impact and low integrity impact. Oracle's June 2026 Critical Security Patch Update includes patches addressing this vulnerability. Oracle strongly advises applying these patches promptly to mitigate the risk. Workarounds include blocking network protocols used in the attack and restricting privileges, though these may disrupt normal operations.
Potential Impact
An unauthenticated attacker with network access via HTTP can exploit this vulnerability to gain unauthorized access to critical data within Oracle Coherence 15.1.1.0.0. This includes the ability to read all accessible data and perform unauthorized update, insert, or delete operations on some data. The vulnerability's scope change means it may affect additional Oracle products relying on Oracle Coherence. The confidentiality impact is high, integrity impact is low, and availability is not impacted. No privileges or user interaction are required for exploitation, increasing the risk severity.
Mitigation Recommendations
Oracle has released a Critical Security Patch Update in June 2026 that addresses this vulnerability among others. Customers are strongly advised to apply the June 2026 Critical Security Patch Update promptly to remediate this issue. Until patches are applied, risk may be reduced by blocking network protocols required for exploitation and by removing unnecessary privileges or access to relevant packages from users. However, these mitigations may impact application functionality. Patch status is not explicitly stated in the advisory content, but the presence of the vulnerability in the June 2026 Critical Security Patch Update strongly indicates an official fix is available. Customers should consult the Oracle advisory at https://www.oracle.com/security-alerts/cspujun2026.html for detailed patch availability and installation instructions.
