Network-reachable authorization bypass requires an existing low-privilege account (PR:L), no user interaction or special complexity, yielding high confidentiality, low integrity, and no availability impact.

Improper Access Control, Missing Authorization vulnerability in MIA Technology Inc. Pizzy Library allows Exploiting Incorrectly Configured Access Control Security Levels.
This issue affects Pizzy Library: from 1.0.0.26250 before 1.3.9.26250.
AnalysisAI
Improper access control in MIA Technology Inc. Pizzy Library versions 1.0.0.26250 through 1.3.9.26250 allows authenticated remote attackers to bypass authorization checks and access resources or actions outside their permission level. The flaw was reported by TR-CERT and carries a CVSS 3.1 base score of 7.1, with high confidentiality impact but only low integrity impact and no availability impact; no public exploit identified at time of analysis.
Technical ContextAI
Pizzy Library is a software component distributed by MIA Technology Inc. (cpe:2.3:a:mia_technology_inc.:pizzy_library). The weakness is classified as CWE-284 (Improper Access Control), with vendor tagging it as an authentication bypass involving 'incorrectly configured access control security levels.' This pattern typically arises when authorization checks rely on misconfigured role/permission tiers, allowing an authenticated principal at one security level to invoke functionality or read data intended for a higher tier. The CWE-284 root cause indicates the library either fails to enforce a check on a protected operation or evaluates the security level against an attacker-controllable or inconsistently-applied policy.
RemediationAI
Upstream fix available; the version range 'before 1.3.9.26250' indicates that 1.3.9.26250 is the first non-vulnerable release, so administrators should upgrade Pizzy Library to 1.3.9.26250 or later as obtained from MIA Technology Inc. Confirm the build against the TR-CERT advisory at https://siberguvenlik.gov.tr/guvenlik-bildirimleri/detay/tr-26-0383. Until the upgrade is deployed, compensating controls should focus on the authorization layer: restrict network reachability of the library's endpoints to trusted internal segments via firewall or reverse-proxy ACLs (trade-off: breaks legitimate remote integrations); minimize the population of low-privilege accounts that can reach the affected functionality and audit role assignments for over-broad security levels (trade-off: operational overhead and possible workflow disruption); and enable detailed access logging on the affected endpoints to detect anomalous cross-tier access (trade-off: increased log volume and storage cost).
