Oracle Time and Labor CVE-2026-61015

The vulnerability requires unauthenticated network access via HTTP to a host running Oracle E-Business Suite with the Oracle Time and Labor module (versions 12.2.3-12.2.15) deployed. The CVSS AC:H rating indicates that exploitation is not straightforward - a specific, non-obvious condition must be met, likely involving particular request parameters, internal state, or sequencing within the Internal Operations component; however, the exact technical prerequisite is not disclosed in the available advisory. No credentials or prior authentication are required (PR:N). No user interaction is needed (UI:N). Exploitation is limited by: the high attack complexity (reliable exploitation requires overcoming an unspecified technical barrier); impact confined to read-only access to a subset of Time and Labor data with no write or availability impact; and the typical enterprise-internal deployment of Oracle EBS, which places the attack surface behind corporate network boundaries in well-managed environments.

The CVSS 3.1 base score of 3.7 (Low) is a reasonable reflection of real-world risk given the available signals. AV:N confirms network reachability, but AC:H significantly constrains exploitability - the attack cannot be reliably automated or mass-deployed without overcoming a technical hurdle. PR:N and UI:N mean no account or victim interaction is required, which slightly elevates concern, but the scope is unchanged (S:U) and impact is limited to C:L with no integrity or availability consequences. No EPSS score is available in the provided data, no KEV listing exists, and no public proof-of-concept has been identified - all of which further support treating this as low operational priority for most organizations. The 'Authentication Bypass' tag raises the conceptual severity somewhat, as auth bypasses can serve as a stepping stone in chained attacks; however, the limited data exposure described constrains standalone impact. Oracle EBS is typically deployed in internal enterprise networks, and internet-exposed EBS instances are considered a misconfiguration - if properly segmented, the effective attack surface is significantly reduced beyond what the CVSS network vector implies.

An attacker with network access to an Oracle EBS HTTP endpoint crafts a specially constructed unauthenticated HTTP request targeting the Internal Operations component of Oracle Time and Labor, exploiting a flaw in the authentication validation logic. After satisfying the high-complexity condition (such as a specific request structure or state), the attacker receives a partial data response containing a subset of Time and Labor records - such as employee scheduling or labor data - without any valid session or credentials. No public proof-of-concept exists at time of analysis, meaning this scenario remains theoretical and requires non-trivial exploit development.
