Critical CVSS 10
CVE-2026-45336
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.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and degrade the service. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Credentials are hard-coded in the product and identical across every installation.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
