CVE-2025-66291 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Orangehrm Orangehrm. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Information Repositories (T1213); ranked at the 10th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Vulnerability Data
OrangeHRM is a comprehensive human resource management (HRM) system. From version 5.0 to 5.7, the interview attachment retrieval endpoint in the Recruitment module serves files based solely on an authenticated session and user-supplied identifiers, without verifying whether the requester has…

permission to access the associated interview record. Because the server does not perform any recruitment-level authorization checks, an ESS-level user with no access to recruitment workflows can directly request interview attachment URLs and receive the corresponding files. This exposes confidential interview documents—including candidate CVs, evaluations, and supporting files—to unauthorized users. The issue arises from relying on predictable object identifiers and session presence rather than validating the user’s association with the relevant recruitment process. This issue has been patched in version 5.8.

Why these techniques?
The improper authorization vulnerability enables low-privileged authenticated users to access sensitive recruitment data (e.g., candidate CVs, evaluations) from the OrangeHRM information repository via predictable identifiers without permission checks.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization checks on every request to the interview attachment endpoint so that only users associated with the recruitment record can retrieve files.
Limits an authenticated ESS user to the minimum set of recruitment objects required by their role, preventing access to interview attachments outside their permitted workflows.
Enforces information-flow rules that would block unauthorized retrieval of interview documents even when a valid session exists.

PR.AA-05 directly enforces least-privilege authorization that blocks most unauthorized disclosures, yet CWE-200 also arises from logging, error messages, and side-channel paths that access controls alone do not address.
PR.DS-10 mostly prevents CWE-200 by directly eliminating unauthorized access to sensitive data-in-use, yet only partially addresses the weakness because CWE-200 spans many other exposure vectors outside runtime protection.
PR.IR-01's segmentation/zero-trust controls largely eliminate network-level unauthorized access paths that enable exposure, yet CWE-200 spans many additional vectors (API responses, logs, app logic) that network controls alone cannot close.
Secure SDLC practices catch most exposure flaws via design, testing and release controls, yet CWE-200 spans runtime/config issues a single development outcome cannot fully close.
PR.AA-01 supplies proper credential lifecycle controls that reduce unauthorized access paths, yet leaves many other exposure vectors (error messages, logging, side channels, etc.) unaddressed.
Authentication verifies actor identity and is a prerequisite for access decisions, yet addresses only one facet of the broad set of exposure vectors in CWE-200.

Restricting anonymous or unknown access and encrypting high-value information limits the exposure of sensitive data that would otherwise be obtainable by unauthorized actors.
Suppressing system details, error specifics, and previous log-on information until successful authentication reduces the information an unauthenticated attacker can gather.
By requiring owners to assign sensitivity labels and corresponding handling rules, the control ensures that information is not left unmarked and therefore reduces the chance that sensitive data will be exposed to unauthorized actors.
Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.
Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.
Requiring defined procedures, assigned roles, and technical/organizational measures for handling PII reduces the chance that sensitive personal data will be exposed to unauthorized actors through inadequate handling or missing safeguards.
