CVE-2026-23843 Vulnerability Summary

CVE-2026-23843: teklifolustur_app is a web-based PHP application that allows users to create, manage, and track quotes for their clients. Prior to commit dd082a134a225b8dcd401b6224eead4fb183ea1c, an Insecure Direct Object Reference (IDOR) vulnerability exists in the offer view functionality. Authenticated users can manipulate the offer_id parameter to access offers belonging to other users. The issue is caused by missing authorization checks ensuring that the requested offer belonged to the currently authenticated user. Commit dd082a134a225b8dcd401b6224eead4fb183ea1c contains a patch.

Assessing the Risk of CVE-2026-23843

Access Complexity Graph

The exploitability of CVE-2026-23843 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-23843

CVE-2026-23843 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-23843, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
