Oracle Time and Labor CVE-2026-62507

Exploitation requires a valid low-privileged account with network access to the Oracle E-Business Suite application tier via HTTP - anonymous or unauthenticated access is insufficient per the PR:L CVSS metric. The AC:H metric indicates that specific, difficult-to-reproduce conditions must be met during exploitation; these conditions are not fully enumerated in the public advisory but likely involve precise request sequencing, timing, or internal state dependencies within the Internal Operations component. The 'Authentication Bypass' tag suggests the flaw activates within the context of an authenticated session when the attacker interacts with internal authorization pathways that do not properly validate the caller's role. Exploitation is limited to the Time and Labor module's data scope (S:U, unchanged scope) and does not affect confidentiality or availability. Factors limiting real-world exploitation include the AC:H complexity barrier, the requirement for a valid EBS credential, and the absence of any known public exploit.

The CVSS 3.1 base score of 5.3 (Medium) reflects a constrained attack profile: AC:H indicates exploitation requires satisfying specific, difficult-to-meet conditions; PR:L requires a valid low-privileged account. Despite these constraints, I:H means successful exploitation yields full write access to all Time and Labor data, which in payroll-integrated EBS environments can have significant downstream business impact. No EPSS score is provided in the supplied data. There is no CISA KEV listing and no confirmed public proof-of-concept, placing exploitation probability in the speculative range. The 'Authentication Bypass' tag introduces an important nuance - while CVSS assigns PR:L, the tag implies that once authenticated, the attacker may escalate internal permissions beyond their granted role, potentially widening the realistic impact. The AC:H constraint is the primary real-world mitigator; defenders should not discount this vulnerability in EBS environments where many users hold low-level credentials.

An attacker holding a low-privileged EBS account - such as a regular employee with time-entry access - crafts a specific HTTP request sequence to the Internal Operations component that satisfies the high-complexity exploitation condition, bypassing internal authorization checks. Upon success, the attacker gains the ability to create, modify, or delete Time and Labor records across the application, potentially manipulating payroll inputs, falsifying hours, or erasing audit trails. No public proof-of-concept has been identified, meaning this scenario currently requires non-trivial attacker knowledge of EBS internals.
