AnalysisAIv1 – Sep 15, 2026

Authorization bypass in IceHRM before 36.0.0 lets any authenticated employee read coworkers' HR records by substituting an arbitrary employee ID in seven REST sub-resource endpoints covering skills, education, certifications, languages, leave, attendance and status. CVSS 4.0 scores the flaw 7.1 (AV:N/AC:L/PR:L/UI:N, VC:H only), reflecting a low-effort, easily automated disclosure of sensitive personnel data rather than code execution. No public exploit code was identified at time of analysis and the issue is not listed in CISA KEV; a vendor fix is available in release v36.0.0.
