Critical authentication bypass
Account takeover via reset flow + weak session binding — stopped before mass exploitation.
Impact
Full account compromise for enterprise tenants, potential regulatory exposure, and reputational risk with flagship customers.
Fix
We delivered a prioritized remediation plan: hardened reset tokens, strict session binding, and monitoring hooks. Fixes were validated with a focused retest.
Technical finding
We identified a logical flaw in the password-reset flow combined with weak session fixation controls, allowing an attacker to assume a victim session without credentials.
Problem context
The customer’s release cycle prioritized features over auth hardening. Penetration testing had not been performed in over two years.
