CVE-2025-66291 — OrangeHRM is Vulnerable to Improper Authorization Allowing Unauthorized Access to Interview Attachments
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+1
- Technical severity (medium)+3
- Automatable exploitation (SSVC)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
- Documented patch — github.com (NIST National Vulnerability Database)
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Orangehrm Orangehrm).
- Apply the fixed version or the patch documented under Remediation.
- Search available logs for exploit probes matching the vulnerability class (info disclosure), errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Look for anomalous data read/export volumes and access to sensitive records.

What should defenders know first?
CVE-2025-66291 is "OrangeHRM is Vulnerable to Improper Authorization Allowing Unauthorized Access to Interview Attachments", rated Medium. It affects Orangehrm (Orangehrm); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.3 describes technical severity. EPSS 0.20% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
