CVE-2026-46918 is a critical security vulnerability affecting Oracle Process Manufacturing Product Development component of Oracle E-Business Suite versions 12.2.3 through 12.2.15. The flaw allows a low privileged attacker with network access via HTTP to compromise the product, potentially resulting in complete takeover. The vulnerability also has a scope change, meaning exploitation may impact additional Oracle products beyond the initially affected component. The CVSS 3.1 score is 9.9, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and high impacts on confidentiality, integrity, and availability. Oracle’s June 2026 Critical Security Patch Update addresses this vulnerability among 245 others. Oracle strongly recommends applying the patch without delay. Workarounds include blocking network protocols used by the attack and removing unnecessary privileges, but these may affect application functionality.

Successful exploitation of CVE-2026-46918 can lead to complete compromise of Oracle Process Manufacturing Product Development, including full confidentiality, integrity, and availability loss. The vulnerability is exploitable remotely over HTTP by a low privileged attacker without user interaction. Additionally, the scope change indicates that other Oracle products may also be impacted by attacks leveraging this vulnerability, potentially broadening the impact beyond the initially affected product.

Oracle has released a Critical Security Patch Update in June 2026 that addresses CVE-2026-46918. Customers should apply this patch promptly to remediate the vulnerability. Until the patch is applied, risk may be reduced by blocking network protocols required for exploitation and by removing unnecessary privileges from users who do not need them. However, these mitigations may disrupt normal application functionality. Oracle strongly advises remaining on actively supported versions and applying security patches without delay.
