CVE-2026-46826: Vulnerability in the Oracle Payroll product of Oracle E-Business Suite (component: Internal Operations)

Synopsis

An easily exploitable vulnerability in the Internal Operations component of Oracle Payroll (part of Oracle E-Business Suite, versions 12.2.3 through 12.2.15) allows a low-privileged, network-based attacker to fully compromise the application. The attacker requires only a standard user account and network access over HTTPS with no special conditions to meet. Successful exploitation results in complete takeover of Oracle Payroll, affecting confidentiality, integrity, and availability. No fix version has been published yet; HarborGuard tracks this advisory and will make a patched rebuild available as soon as Oracle ships a correction.

HarborGuard Coverage

Exploit Conditions

• Network reachabilityRequired

  The attacker must reach the Oracle Payroll service over the network via HTTPS; the application's network exposure directly determines attack surface.

• AuthenticationRequired

  A low-privilege account is sufficient; any authenticated application user can initiate the attack without needing elevated or administrative rights.

• Victim interactionNot required

  No user interaction is needed; the attacker can exploit the vulnerability entirely without involving another person.

• Attack complexityDetail

  Attack complexity is low, meaning the exploit is reliable and requires no special conditions such as race wins, memory layout dependencies, or environmental prerequisites.

Blast Radius

• Reads all payroll data accessible to the application, including salary records, tax information, and employee personal details.
• Modifies or deletes payroll records, potentially corrupting pay runs, audit trails, and compliance data.
• Crashes or disables the Oracle Payroll service, interrupting payroll processing for the affected organization.
• Achieves full application takeover, enabling lateral movement to other Oracle E-Business Suite components sharing the same runtime or database.
