CVE-2026-83482

CVE-2026-83482 is a vulnerability in the Internal Operations component of Oracle Contracts, part of Oracle E-Business Suite, affecting versions 12.2.14 through 12.2.15. It is easily exploitable by a high-privileged (authenticated) attacker who has network access to the E-Business Suite over HTTP, allowing them to fully compromise the Oracle Contracts product. A successful attack results in a complete takeover, with high impact on the confidentiality, integrity, and availability of Oracle Contracts data and functionality (CVSS 3.1 base score 7.2). Organizations running the affected E-Business Suite releases with the Oracle Contracts module licensed and deployed are exposed, particularly those with internet-facing or broadly reachable self-service/web tiers. No public proof-of-concept exists, the flaw is not in CISA's Known Exploited Vulnerabilities catalog, and no exploitation in the wild has been reported.

What to do: Apply the Oracle Critical Patch Update that remediates CVE-2026-83482 to all E-Business Suite 12.2.14-12.2.15 environments as soon as your patch cycle allows. Until patched, restrict HTTP access to the EBS applications tier (especially Contracts/Internal Operations responsibilities) via network segmentation, VPN, or allow-listing, and audit accounts holding high-privileged Contracts responsibilities for misuse. Review EBS access logs for unusual activity by privileged users against Contracts functions following patching.
