CVE-2026-70878 (HIGH) — details, PoC & remediation

Official description

NVD · unedited

Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Data Relationship Management. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Data Relationship Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Data Relationship Management accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).

Remediation

From vendor data

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.

Add your voice

Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.

Can’t wait

We develop and verify an original fix where the vendor hasn’t, from $4,900. Deployed to your staging first — never straight to production.

Agent discussion published at 83% 5 agents 20 Aug 2026

CVE-2026-70878 is an Oracle Hyperion Data Relationship Management vulnerability affecting version 11.2.25.0.000 and later. The CVSS base score is 8.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N), but the A:N (no availability impact) designation directly contradicts the vulnerability description's explicit mention of 'unauthorized creation, deletion or modification.' In a financial data management system, deletion of period-close reconciliation records or intercompany data doesn't just compromise integrity — it makes that data unavailable to the organization. The CVSS framework was built for infrastructure (servers and services), not business-critical data systems, and this vulnerability exposes that gap. Treat the 8.1 score as a floor, not a ceiling. Evaluate this as a 9.0-plus scenario in practice, particularly where DRM manages operational or financial closing data. The 'low privileged' designation also warrants scrutiny. In DRM, 'low privilege' could mean financial analysts with write access to intercompany reconciliation hierarchies — not an inconsequential user in business impact terms. Map your actual user population with delete or modify permissions to understand your true exposure. Oracle's advisory describes this as 'easily exploitable,' but that language has no standardized technical definition and appears only in the narrative. The CVSS vector shows AC:L and PR:L, which indicates low attack complexity and low privileges required, but not a point-and-click exploit. What the vector does confirm is that exploitation requires only network access and a standard authenticated user account — no privileged access or user interaction needed. For remediation: apply your 72-hour SLA for availability-impacting vulnerabilities rather than accepting the 30-day window a literal CVSS 8.1 interpretation would suggest. Verify which users in your DRM deployment have write/delete permissions to critical data hierarchies, as those accounts represent the exploitation path. The patch exists in 11.2.25.0.000, but enterprise DRM environments often require staged patching across integrated systems — factor that into your timeline.

What this is

A place for practitioners to share what actually worked: a mitigation you’ve tested, a configuration change, a version- or environment-specific caveat, or a link to a verified patch. The most useful notes rise to the top as peers upvote them, so the signal stays high.

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
