The vulnerability impacts versions 12.2.6 through 12.2.15. A low-privileged attacker with network access via HTTPS can exploit this vulnerability to gain unauthorized access to sensitive data. While the vulnerability resides in Oracle Public Sector Financials (International), successful exploitation may significantly impact other Oracle products. This can lead to unauthorized access to critical data or complete access to all Oracle Public Sector Financials (International) accessible data.

Attack Chain

  1. Attacker gains network access to the target Oracle E-Business Suite instance via HTTPS.
  2. Attacker authenticates to the Oracle E-Business Suite with low-privileged credentials.
  3. Attacker crafts a malicious HTTPS request targeting the vulnerable Authorization component within Oracle Public Sector Financials (International).
  4. The crafted request bypasses authorization checks due to the vulnerability in the Authorization component.
  5. The application processes the malicious request without proper authorization, allowing the attacker to access restricted data.
  6. Attacker gains unauthorized read access to sensitive data within Oracle Public Sector Financials (International).
  7. The attacker may leverage this initial access to pivot and compromise other related Oracle products due to the scope change impact.
  8. Attacker exfiltrates sensitive data or uses the unauthorized access to perform other malicious activities within the compromised system.

Impact

Successful exploitation of CVE-2026-46823 can result in unauthorized access to critical data or complete access to all data accessible within Oracle Public Sector Financials (International). While the vulnerability exists within this specific component, the impact may extend to other Oracle products integrated with the E-Business Suite. This could lead to a significant breach of confidentiality, potentially exposing financial records, sensitive government data, or other confidential information.

Recommendation

  • Apply the Oracle patch for CVE-2026-46823 to remediate the vulnerability in Oracle Public Sector Financials (International).
  • Deploy the Sigma rule "Detect CVE-2026-46823 Exploitation Attempt - Malicious URI Access" to monitor for exploitation attempts targeting the vulnerable component.
  • Review and restrict network access to the Oracle E-Business Suite instance, limiting access to authorized users and systems to mitigate the risk of unauthorized access.

The vulnerability resides in the Common Components and impacts supported versions from 12.2.3 through 12.2.15. A low privileged attacker with network access via HTTP can easily exploit this vulnerability. While the vulnerability exists in Oracle Financials Common Modules, successful attacks can significantly impact other products within the E-Business Suite environment, leading to unauthorized access to critical or all accessible data within Oracle Financials Common Modules. This vulnerability poses a significant risk to the confidentiality of sensitive financial data.

Attack Chain

  1. The attacker gains network access to the target Oracle E-Business Suite environment via HTTP.
  2. The attacker identifies a vulnerable endpoint within the Common Components of Oracle Financials Common Modules.
  3. The attacker crafts a malicious HTTP request to exploit the CVE-2026-46821 vulnerability.
  4. Due to insufficient access controls, the attacker bypasses authentication checks.
  5. The attacker gains unauthorized access to sensitive data within the Oracle Financials Common Modules.
  6. The attacker escalates privileges within the application due to the scope change impact.
  7. The attacker accesses critical financial data, such as account balances, transaction history, or customer information.
  8. The attacker may exfiltrate the compromised data or use it for further malicious activities within the E-Business Suite environment.

Impact

Successful exploitation of CVE-2026-46821 allows low-privileged attackers to gain unauthorized access to critical data within Oracle Financials Common Modules. Given the scope change, attacks can impact additional products in the E-Business Suite environment. The confidentiality of sensitive financial data is compromised, potentially leading to financial losses, reputational damage, and regulatory fines. The number of affected organizations depends on the adoption rate of the vulnerable E-Business Suite versions.

Recommendation

  • Apply the latest patches and updates provided by Oracle for the E-Business Suite to address CVE-2026-46821.
  • Implement network segmentation and access controls to limit the attack surface and prevent unauthorized network access as this is the initial attack vector.
  • Monitor HTTP traffic for suspicious requests targeting Oracle Financials Common Modules endpoints using a web application firewall (WAF) or intrusion detection system (IDS).
  • Deploy the Sigma rule "Detect CVE-2026-46821 Exploitation Attempt via HTTP Request" to identify exploitation attempts in web server logs.
  • Review and enforce the principle of least privilege to minimize the impact of successful exploitation by limiting the scope of accessible data.
