Monthly
Oracle Coherence (Core component) versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 can be fully taken over by a low-privileged attacker who can reach the HTTP interface, per Oracle's Critical Security Patch Update. The CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:N, C/I/A all High) confirms a network-reachable but difficult-to-exploit flaw that yields complete compromise of the data grid rather than a limited data leak. No CISA KEV listing, public exploit code, or EPSS score is present in the supplied intelligence, so no public exploit identified at time of analysis and active exploitation is unconfirmed.
Oracle Coherence versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 contain a flaw in the Core component that allows a low-privileged attacker with TCP network access to create, delete, or modify critical clustered data and to read all data accessible to Coherence. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) yields a base score of 8.1, reflecting complete confidentiality and integrity loss with no availability impact and no user interaction. No public exploit code and no CISA KEV entry were present in the supplied intelligence at time of analysis, so exploitation status remains unconfirmed rather than actively exploited.
Full compromise of Oracle Coherence is achievable by low-privileged attackers who can reach the Coherence Core HTTP interface, affecting versions 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 of the Oracle Fusion Middleware product. Successful exploitation gives complete loss of confidentiality, integrity and availability — Oracle describes the outcome as "takeover of Oracle Coherence" — with a CVSS 3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N). No public exploit code has been identified at time of analysis, the flaw is not listed in CISA KEV, and no EPSS score was supplied with the source data, so the practical urgency currently rests on the size of the exposed Coherence estate rather than on observed exploitation.
Oracle Coherence, Oracle's in-memory data grid shipped as part of Fusion Middleware, can be fully taken over by a low-privileged attacker who can reach the cluster over the network in versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. The flaw sits in the Core component and is rated by Oracle as easily exploitable — CVSS 3.1 base 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) — with confidentiality, integrity and availability all fully impacted, meaning compromise of the Coherence cluster rather than a narrow data leak. No EPSS score, CISA KEV entry or public exploit code was provided with this record; the only authoritative source is Oracle's Critical Security Patch Update advisory, so treat exploitation status as unconfirmed (no public exploit identified at time of analysis).
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Caching,CacheStore,Invocation). Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
A partial denial-of-service flaw in the Core component of Oracle Coherence lets a low-privileged, network-positioned attacker degrade availability of the distributed data grid by sending crafted HTTP requests. Versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 of the Oracle Fusion Middleware product are listed as affected by Oracle and mirrored by EUVD (EUVD-2026-79717). The CVSS 3.1 base score is only 4.3 because impact is limited to availability (A:L) with no confidentiality or integrity effect, and no public exploit code or CISA KEV entry was present in the supplied intelligence.
Oracle Coherence 15.1.1.0.0 exposes a narrow local information-disclosure weakness in its Core component that lets an attacker who already holds a low-privileged operating-system logon on the Coherence host read a limited subset of data the process can access. The flaw is rated CVSS 3.1 base 2.5 (AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N), meaning high attack complexity, no integrity or availability impact, and no remote vector. There is no public exploit code and no CISA KEV listing, so this is a low-priority, defense-in-depth item rather than an emergency; Oracle published it through its Critical Patch Update advisory for Fusion Middleware.
Oracle Coherence versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 contain a flaw in the Core component that lets an attacker who already holds a high-privileged account and can log on to the host where Coherence runs make unauthorized updates, inserts or deletions against Coherence-accessible data. The CVSS 3.1 base score is only 1.9 (AV:L/AC:H/PR:H/UI:N, integrity-only), reflecting that exploitation demands local logon, elevated privileges and a difficult-to-achieve condition; confidentiality and availability are not impacted. No public exploit code or CISA KEV entry was present in the supplied intelligence, so this is assessed as a low-priority, defense-in-depth issue rather than an urgent patch item. The vendor-reported nature of the record and the presence of an 'Authentication Bypass' tag that conflicts with the PR:H, integrity-only vector are notable data-quality caveats.
