Unauthenticated HTTP takeover vulnerability in Oracle Coherence Centralized Third Party Jars

IdentifiersCVE-2026-35308

CVE-2026-35308 is a critical vulnerability in Oracle Coherence, within the Centralized Third Party Jars component of Oracle Fusion Middleware. Oracle lists affected supported versions as 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. According to Oracle, the issue is easily exploitable by an unauthenticated attacker with network access via HTTP. Successful exploitation can compromise Oracle Coherence and result in complete takeover of the product. Oracle also notes a scope change, meaning exploitation of the flaw in Coherence may significantly impact additional products that depend on or integrate with the vulnerable component. No specific vulnerable class, function, or library entry point is identified in the provided content.

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.

Successful exploitation can allow a remote unauthenticated attacker to fully compromise Oracle Coherence over HTTP. Oracle rates the issue CVSS 3.1 10.0 with high confidentiality, integrity, and availability impact and scope change (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). In practical terms, exploitation can result in takeover of the Coherence instance, unauthorized access to data handled by the platform, modification of application state or configuration, and disruption of service availability. Because Oracle indicates scope change, compromise may also significantly affect additional connected or dependent products.

Mitigation

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

If immediate patching is not possible, reduce exposure by restricting or blocking the network protocols required for exploitation, specifically limiting untrusted access to the vulnerable HTTP interface. Constrain access to affected Coherence services to trusted management networks, reverse proxies, or allowlisted clients only, and remove unnecessary privileges or access to affected packages from users who do not require them. Oracle notes such mitigations may affect application functionality, should be validated in non-production environments, and are not substitutes for patching.

Remediation

Patch, then assume compromise.

Apply Oracle's June 2026 Critical Security Patch Update addressing CVE-2026-35308. Ensure affected Oracle Coherence deployments on versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 are updated to the vendor-fixed release or corresponding security patch level. Oracle also recommends remaining on actively supported versions and upgrading unsupported releases so security fixes are available. Review related Oracle Fusion Middleware and dependent component patch guidance where Coherence is embedded in broader product stacks.
