Remotely forgeable admin cookie needs no auth or interaction (AV:N/AC:L/PR:N/UI:N); full admin takeover yields C:H/I:H/A:H, and impact stays within the vulnerable app (S:U).

HireFlow is a web-based interview management system for managing candidates, scheduling interviews, and tracking hiring progress. In 1.2 and earlier, app.py assigns a hard-coded Flask secret_key used to sign session cookies, allowing unauthenticated attackers who know the public source value to forge cookies containing role=admin and user_id values and bypass authentication. The advisory lists version 1.3 as fixed.
AnalysisAI
Authentication bypass in HireFlow interview management system (versions 1.2 and earlier) lets unauthenticated remote attackers forge signed session cookies because app.py ships a hard-coded Flask secret_key. Since the key is present in the public source tree, any attacker can mint cookies asserting role=admin and arbitrary user_id values to gain full administrative access. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target instance runs the affected code path in app.py that uses the hard-coded Flask secret_key (HireFlow 1.2 or earlier) and relies on Flask's signed-cookie sessions for authentication and role enforcement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H) correctly reflects that exploitation is remote, low-complexity, and requires no privileges or user interaction, and the attack is fully deterministic once the source secret is read. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker reads the hard-coded secret_key directly from HireFlow's public GitHub source, then uses Flask/itsdangerous to craft and sign a session cookie containing role=admin and a chosen user_id. They send this forged cookie to a live HireFlow instance and are granted administrative access without any valid credentials, gaining control over candidate records and scheduling data. … |
| Remediation | Upgrade to HireFlow v1.3, the fixed release per the vendor advisory (https://github.com/StratonWebDesigners/HireFlow/releases/tag/v1.3 and GHSA-x53g-jr84-jrv5). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all deployments of HireFlow versions 1.2 or earlier and immediately restrict network access to these systems, disabling external connectivity where feasible. …
