MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Requires an unauthenticated attacker with HTTP network access to the Oracle WebCenter Content Server component, AND successful human interaction from a person other than the attacker (UI:R) - e.g. a legitimate user must interact with attacker-supplied content or a crafted link. This user-interaction dependency is the primary limiting factor, meaning exploitation is not fully automatable and depends on social engineering or an active victim. Affected deployments are limited to Oracle WebCenter Content versions 12.2.1.4.0 and 14.1.2.0.0; environments on patched/other versions or without the Content Server exposed over HTTP are not in scope. Impact is inherently partial (some data integrity modification and partial DoS only; no data disclosure). |
| Impact | This is a moderate-severity issue (CVSS 3.1 base 5.4) whose signals point to limited, opportunistic rather than mass-exploitation risk. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L) shows a network, low-complexity, unauthenticated vector, but exploitation is gated by UI:R - a victim other than the attacker must take an action (e.g. visit/interact with attacker-influenced content), which substantially lowers reliability and scale of attack. Impact is bounded: no confidentiality loss (C:N), only partial integrity (I:L - some unauthorized update/insert/delete) and partial availability (A:L - partial DoS). EPSS is not provided in the input, CISA KEV status is absent (not listed), and no public POC is referenced, so there is no public exploit identified at time of analysis. The absence of EPSS and KEV data means the probabilistic and active-exploitation signals cannot be cross-checked - these should be verified independently before final prioritization. Net: a real but not top-tier priority - patch in normal Oracle CPU cadence rather than emergency, since the user-interaction requirement and modest integrity/availability-only impact make this unlikely to be weaponized at scale. |
| Exploit ScenarioDerived | An unauthenticated attacker crafts malicious content or a link targeting an Oracle WebCenter Content Server reachable over HTTP, then lures an authenticated or privileged user to interact with it. When the victim interacts, the flaw lets the attacker perform limited unauthorized modification of some WebCenter Content data and trigger a partial denial of service. No public proof-of-concept is referenced in the available data. |

Alert meAnalysisAIv1 – Oct 21, 2026
Oracle WebCenter Content 12.2.1.4.0 and 14.1.2.0.0 expose the Content Server component to an unauthenticated HTTP-reachable attack that only succeeds after a non-attacker user interacts with attacker-supplied content or a crafted link, after which the attacker can make limited unauthorized updates, inserts or deletions to accessible data and partially degrade availability. Integrity and availability impacts are both rated Low with no confidentiality exposure, yielding a CVSS 3.1 base score of 5.4 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L); the user-interaction requirement means exploitation is not fully automatable, and no public exploit code was identified at time of analysis. Oracle addressed the issue in its October 2026 Critical Patch Update.
RemediationAI
Vendor-released patch: apply the Oracle Critical Patch Update for October 2026, which is the fix vehicle for this CVE on Oracle WebCenter Content 12.2.1.4.0 and 14.1.2.0.0 (see https://www.oracle.com/security-alerts/cpuoct2026.html); confirm the Content Server component patch is applied on every node, including any clustered or managed-server instances, and note that no patched version number is published in the data available to this analysis, so the CPU matrix must be checked per platform. Because exploitation depends on a victim interacting with attacker-supplied content, the highest-value compensating controls are those that remove the interaction path: place the Content Server HTTP endpoints behind a reverse proxy or WAF that restricts access to known networks and rewrites or blocks suspicious inbound links (trade-off: can break legitimate external partner and mobile access, and generic rules risk false positives against valid Content Server URLs), and disable unused web presentation or guest-facing Content Server features until patching is complete (trade-off: may break integrated applications that rely on those endpoints). Additionally, since the vector is AV:N with no privileges required, do not expose Content Server directly to the internet and prefer VPN or zero-trust access for remote users, accepting the added usability overhead. Monitor repository audit logs for unexpected update, insert or delete activity and for availability blips on the Content Server, and watch the Oracle advisory for any revision or updated patch guidance.

Technical ContextAI · show details
The affected technology is the Content Server component of Oracle WebCenter Content, an enterprise content/document management platform within Oracle Fusion Middleware that serves repository, check-in/check-out and web presentation functionality over HTTP. No CWE identifier was assigned by the reporter, so the root cause must be inferred from the assessed vector: the UI:R component indicates the flaw is triggered through a request that a legitimate user must be induced to make (for example following a crafted link or loading attacker-influenced content), consistent with weak server-side validation or state handling of user-driven requests rather than a pre-authentication memory-corruption primitive. The assessed scope is deliberately narrow - Scope Unchanged, Confidentiality None, Integrity Low, Availability Low - meaning any successful exploitation stays within the Content Server's own security authority and can at most corrupt a limited subset of records or interrupt service partially; there is no read-out of repository data. No CPE data was supplied with the report, so exact platform packaging and dependent-stack details cannot be confirmed beyond the vendor's stated version list.

DescriptionCVE.org
Vulnerability in the Oracle WebCenter Content product of Oracle Fusion Middleware (component: Content Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Content. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebCenter Content accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle WebCenter Content. CVSS 3.1 Base Score 5.4 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L).

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
