CVE-2026-70835 Overview
CVE-2026-70835 is a high-severity vulnerability in the Oracle iRecruitment product within Oracle E-Business Suite, specifically in the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this weakness without user interaction. Successful exploitation grants unauthorized read, creation, deletion, or modification access to all data accessible through Oracle iRecruitment. Oracle disclosed this vulnerability in its Security Alert Advisory published in August 2026.
Critical Impact
An authenticated attacker with low privileges can compromise the confidentiality and integrity of all Oracle iRecruitment data through a single network-based HTTP request.
Affected Products
- Oracle E-Business Suite 12.2.3
- Oracle iRecruitment component within Oracle E-Business Suite versions 12.2.3 to 12.2.15
- Oracle E-Business Suite 12.2.15

Technical Details for CVE-2026-70835
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle iRecruitment, a web-facing module of Oracle E-Business Suite used for candidate recruitment workflows. An authenticated user with low privileges can send crafted HTTP requests that bypass authorization checks intended to isolate application data. The scope remains unchanged, but confidentiality and integrity impacts are high, while availability is not affected. Attackers can read, create, modify, or delete records across the entire iRecruitment data set. The Exploit Prediction Scoring System (EPSS) currently places this issue in the 32nd percentile of exploit likelihood.
Root Cause
Oracle has not published detailed root-cause information beyond the advisory metadata. The impact profile — confidentiality and integrity compromise via HTTP with low privileges — is consistent with broken access control or insufficient authorization enforcement at the application layer. This class of flaw typically arises when server-side handlers trust client-supplied identifiers or role attributes without validating that the requesting session has entitlement to the target object.
Attack Vector
Exploitation requires network reachability to the Oracle E-Business Suite HTTP interface and a valid low-privileged user account within the iRecruitment application. No user interaction is needed, and attack complexity is low. Because iRecruitment is often exposed to external candidates and internal HR users, the pool of eligible authenticated attackers can be broad. Technical details are described in prose only; no verified proof-of-concept code is publicly available. Refer to the Oracle Security Alert August 2026 for authoritative details.
Detection Methods for CVE-2026-70835
Indicators of Compromise
- Unexpected HTTP POST or GET requests to iRecruitment Internal Operations endpoints from low-privileged user sessions.
- Bulk read, create, update, or delete operations against iRecruitment tables outside of normal recruiter workflows.
- New or modified candidate, requisition, or vacancy records lacking a corresponding audit trail from a recruiter role.
Detection Strategies
- Review Oracle E-Business Suite application access logs and FND_LOG_MESSAGES for anomalous access patterns tied to iRecruitment responsibilities.
- Correlate HTTP access logs from the Oracle HTTP Server tier with application session identifiers to detect authorization anomalies.
- Baseline normal iRecruitment usage per role and alert on deviations in request volume or record modification counts.
Monitoring Recommendations
- Forward Oracle E-Business Suite middle-tier and database audit logs to a centralized analytics platform for correlation.
- Enable Oracle Fine-Grained Auditing on iRecruitment schema tables to capture direct data modifications.
- Monitor authentication events for low-privileged accounts exhibiting elevated request rates against Internal Operations URLs.
How to Mitigate CVE-2026-70835
Immediate Actions Required
- Apply the patches referenced in the Oracle Security Alert August 2026 to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
- Inventory all Oracle iRecruitment deployments and validate exposure of the HTTP tier to untrusted networks.
- Review and reduce the number of low-privileged accounts with access to iRecruitment.
Patch Information
Oracle released fixes for CVE-2026-70835 as part of the Oracle Security Alert published on August 18, 2026. Administrators should follow the deployment guidance in the Oracle Security Alert August 2026 and apply the corresponding Critical Patch Update to all affected E-Business Suite environments.
Workarounds
- Restrict network access to Oracle iRecruitment HTTP endpoints using a web application firewall or reverse proxy allow-list until the patch is deployed.
- Disable or unassign the iRecruitment responsibility for user accounts that do not require it.
- Enforce multi-factor authentication and strong password policies on all Oracle E-Business Suite accounts to raise the barrier for account abuse.
