Oracle Hyperion DRM CVE-2026-70882

Exploitation requires the attacker to hold a valid low-privileged account with network access to Oracle Hyperion DRM via HTTP - anonymous unauthenticated exploitation is not consistent with the PR:L CVSS metric. A person other than the attacker (e.g., a more privileged DRM user) must perform some interactive action as part of the attack, such as clicking a crafted link or loading a malicious resource - without this interaction, the attack chain does not complete. The vulnerable version is specifically 11.2.25.0.000; deployments on other patch levels are not confirmed as affected by available data. The scope change condition requires that the DRM instance be integrated with other Oracle Hyperion products for the cascading impact to materialize. What limits exploitation: the UI:R requirement prevents fully automated or spray-and-pray attacks; the need for a legitimate low-privilege account adds a barrier compared to unauthenticated flaws; no high-privilege credential is required but a valid account is mandatory.

The CVSS 3.1 base score of 8.7 is well-supported by the vector: AV:N (network-accessible HTTP endpoint), AC:L (no special conditions or race requirements), PR:L (low-privileged account sufficient), UI:R (victim interaction required, tempering the worst-case scenario), S:C (scope change elevates the score by capturing cascading impact), C:H and I:H (full data compromise in both confidentiality and integrity dimensions), and A:N (no availability degradation). The UI:R requirement is a meaningful limiting factor - unauthenticated mass exploitation is not possible, and the attacker must socially engineer a victim into taking an action. There is no EPSS score available in the provided data, and the vulnerability is absent from the CISA KEV catalog, suggesting no confirmed opportunistic or widespread exploitation at this time. The authentication bypass tag alongside PR:L in the CVSS vector is worth flagging: it implies the attacker already holds a low-privilege account but uses the bypass to elevate effective access, rather than bypassing login entirely from an unauthenticated state - security teams should verify this distinction with Oracle's advisory. Despite the absence of confirmed exploitation, the scope change and high C/I impacts mean even a mid-sized IT organization in swidnica managing financial master data on Hyperion DRM should treat this patch cycle as urgent, given the potential for cascading EPM suite compromise.

An attacker with a low-privileged Oracle Hyperion DRM account crafts a malicious HTTP request or link exploiting the authentication bypass flaw, then induces a higher-privileged user (e.g., a DRM administrator) to interact with it - through phishing or a malicious link embedded in a shared report. Upon the victim's interaction, the attacker's session or request gains unauthorized access to critical master data hierarchies, enabling full read and write operations across DRM-managed data, with potential spillover into integrated Oracle EPM products such as Hyperion Planning or FDMEE. No public proof-of-concept code has been identified at time of analysis.
