   R02 — ASVS authz

   R03 — API BOLA

   R09 — PostgreSQL RLS/constraints

   Read the assigned sections; map the mechanism, threat model and trade-offs.

2. 02

   Project implementation

   120 min· build · integrate · debugtimer

   Audit P1 API authentication, conversation ownership, SQL persistence, and memory ACLs. Complete `C10` (Adaptive memory & personalized state): add user preference/task-state lifecycle (write, retrieve, correct, TTL expire, and delete) with strict owner/tenant binding and trust labels.

   Build, integrate, debug and improve the increment in the active project.

3. 03

   Security lab

   60 min· attack your own systemtimer

   Run cross-user BOLA and memory-poisoning tests against all P1 conversation and C10 memory endpoints; fix any bypasses.

   Test the abuse case, failure path, authorization bypass or resource limit.

4. 04

   Verification & evidence

   30 min· test · record evidencetimer

   100% passing cross-user SQL and C10 memory lifecycle/isolation test suite.

   Add or run regression tests; record the 9-point evidence record.

5. 05

   Deliberate practice & Socratic review

   30 min· explain aloud · update gapstimer

   Answer the 8 Socratic questions without notes: What? Why? How? What if? Why not? How can I prove it? Where can it break? What have I learned?

   Re-explain the hardest concept aloud, inspect one edge case, update the gap log.

  API1:2023 Broken Object Level Authorization

  Defines BOLA precisely and gives the three attack scenarios plus the prevention rule (compare the object's owner to the authenticated caller on every access) that your conversation-ownership and memory-ACL audit tests.

  Understanding the #1 OWASP API vulnerability, Broken Object Level Authorization #cybersecurity.

  Corey Ball walks real BOLA breaches and why scanners miss them, which frames the manual replay-across-accounts test you run against conversation and memory endpoints.

  API1: Broken Object Level Authorization

  The canonical definition of BOLA with attack examples and the object-level check that must live in application code, which is exactly what the day tests.

  A deliberately broken API with 13 challenges spanning BOLA, broken auth, and mass assignment, giving a safe local target to prove your ownership checks actually return 403/404 cross-account.
