CVE-2026-62479 is a privilege management flaw residing in the Internal Operations component of Oracle Public Sector Financials, which is part of the Oracle E-Business Suite. The vulnerability affects versions 12.2.3 through 12.2.15 inclusive. At its core, the issue stems from improper access control validation within the component’s request-handling logic — specifically, the application fails to adequately verify whether a low-privileged user possesses the necessary enments to perform certain internal operations on financial data objects.
An attacker exploiting this vulnerability must first authenticate to the Oracle E-Business Suite instance with a low-privileged account (e.g., a basic user or a limited operator role). Once authenticated, the attacker crafts malicious HTTP requests targeting the Internal Operations module. These requests are designed to manipulate parameters that govern data access permissions, effectively tricking the application into bypassing its normal authorization checks. The attack vector is network-based over HTTP, and the exploitation complexity is considered low, meaning that no sophisticated techniques or special conditions are required beyond standard web request manipulation.
However, the attack is not entirely autonomous — it requires human interaction from a victim user who is distinct from the attacker. This interaction typically manifests as the victim clicking a crafted link or performing a seemingly legitimate action within the application that triggers the attacker’s payload. This user-assisted component makes the attack slightly less reliable but still highly feasible in social-engineering scenarios. Critically, the vulnerability exhibits a scope change, meaning that a successful compromise within the Public Sector Financials module can extend beyond its own security boundary and affect other products or components within the broader Oracle E-Business Suite environment.
Once exploited, the attacker gains the ability to perform unauthorized operations on a subset of accessible data. Specifically, they can read sensitive financial records that should be restricted, as well as insert, update, or delete data entries without proper authorization. The impact is limited to partial confidentiality and integrity breaches — the attacker cannot fully compromise the entire system or achieve a denial-of-service condition. The CVSS 3.1 base score is 5.4, which classifies this as a Medium-severity vulnerability. The vector string is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, reflecting the network attack surface, low complexity, low privileges required, user interaction requirement, changed scope, and low impacts on confidentiality and integrity.
As of the publication date, no public exploit code has been released, and technical details remain scarce. However, the vulnerability is considered easily exploitable in theory, and threat intelligence sources estimate that an exploit could command a price between $5,000 and $25,000 on underground markets. The CVE was assigned on July 14, 2026, and the NVD published the record on July 21, 2026. Oracle has acknowledged the issue and is expected to address it in an upcoming Critical Patch Update (CPU).
DailyCVE Form:
Platform: Oracle E-Business Suite
Version: 12.2.3-12.2.15
Vulnerability: Improper Access Control
Severity: Medium (CVSS 5.4)
Date: 2026-07-21
Prediction: Expected Patch Date: 2026-10-15
What Undercode Say:
Analytics indicate that the vulnerability is remotely exploitable with low complexity, requiring only low-privileged credentials and user interaction. The scope change increases the potential blast radius, making it a priority for organizations running affected versions. EPSS score is 0.00213, suggesting a low probability of active exploitation in the wild within the first 30 days, but the ease of exploitation and the availability of proof-of-concept development could elevate this risk over time. Security teams should prioritize asset discovery to identify all instances of Oracle Public Sector Financials within their environment.

Exploit:
Currently, there is no publicly available exploit for CVE-2026-62479. The vulnerability requires the attacker to have a low-privileged account on the target Oracle E-Business Suite instance and to lure an authenticated user with higher privileges (or at least a distinct user) into interacting with a malicious link or request. The attack leverages crafted HTTP requests that manipulate access control parameters within the Internal Operations component, causing the application to grant unauthorized read, insert, update, or delete permissions on financial data. While the exact technical details are undisclosed, the vulnerability is classified as easily exploitable, and underground markets have assigned an estimated exploit price of $5,000–$25,000. Organizations should assume that threat actors are actively analyzing the patch diff once it becomes available, and exploit development is likely to follow shortly after.
Protection:
The primary protection against CVE-2026-62479 is to apply the official security patch from Oracle as soon as it is released. Until a patch is available, organizations should implement the following compensating controls:
– Restrict network access to the Oracle E-Business Suite administrative interfaces, allowing only trusted IP ranges.
– Enforce strict role-based access control (RBAC) and regularly review user privileges to ensure that low-privileged accounts have the minimum necessary permissions.
– Deploy web application firewall (WAF) rules to inspect and block anomalous HTTP requests targeting the Internal Operations module, particularly those containing suspicious parameter manipulation patterns.
– Enable comprehensive auditing and logging for all access to the Public Sector Financials module, with real-time alerts for unauthorized data modification attempts.
– Educate users about social engineering risks, as the vulnerability requires human interaction from a victim.
– Consider temporary isolation or deactivation of the Internal Operations component if business impact is acceptable, until a patch can be applied.
Impact:
Successful exploitation of CVE-2026-62479 results in unauthorized read, insert, update, and delete access to a subset of Oracle Public Sector Financials data. This can lead to:
– Confidentiality Impact (Low): Exposure of sensitive financial records, including transaction details, budget information, and constituent data, which could be used for further reconnaissance or identity theft.
– Integrity Impact (Low): Unauthorized modification or deletion of financial data, potentially leading to inaccurate reporting, financial discrepancies, and compliance violations.
– Scope Change (Yes): The attack can extend beyond the Public Sector Financials module to impact other products within the Oracle E-Business Suite, increasing the potential for lateral movement and broader system compromise.
– Operational Disruption: While not directly causing denial of service, the integrity violations can force organizations to spend significant time and resources on data validation, forensic investigation, and system restoration.
– Regulatory and Reputational Risk: For public sector entities, a breach of financial systems can erode public trust and trigger regulatory scrutiny under frameworks such as FISMA, GDPR, or local data protection laws.
Given the medium severity and the requirement for user interaction, the immediate risk is moderate, but organizations should not delay remediation given the ease of exploitation and the potential for scope expansion across the E-Business Suite environment.
