Vulnerable vs. safe
Flagged by this check
CORS_ALLOW_ALL_ORIGINS = TruePasses - the safe pattern
CORS_ALLOW_ALL_ORIGINS = FalseWhy it matters & how to fix it
CORS is configured to allow all origins ('*', CWE-942). Combined with credentials this lets any site read authenticated responses. Restrict allow_origins / CORS_ALLOWED_ORIGINS to an explicit allow-list of trusted origins, and never pair '*' with allow_credentials=True.
