CVE-2026-7817 Vulnerability Summary

CVE-2026-7817: Local file inclusion (LFI) and server-side request forgery (SSRF) vulnerabilities in pgAdmin 4 LLM API configuration endpoints. User-supplied api_key_file and api_url preferences were passed to the LLM provider clients without validation. An authenticated user could read arbitrary server-side files by pointing api_key_file at any path readable by the pgAdmin process, or coerce pgAdmin into making requests to internal targets (e.g. cloud metadata services such as 169.254.169.254) by setting api_url, exploiting the chat path and model-list endpoints. Fix restricts api_key_file to the user's private storage (server mode) or home directory (desktop mode), enforces a printable-ASCII key shape and a 1024-byte read cap, and gates api_url against a configurable allow-list (config.ALLOWED_LLM_API_URLS) at every entry point. This issue affects pgAdmin 4: before 9.15.

Assessing the Risk of CVE-2026-7817

Access Complexity Graph

The exploitability of CVE-2026-7817 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-2026-7817

CVE-2026-7817 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-2026-7817, 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

Below is the Impact Analysis for CVE-2026-7817, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2026-7817 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: None
    CVE-2026-7817 poses no threat to data integrity.
  • Availability: None
    CVE-2026-7817 does not impact system availability.

CWE-552

CAPEC Common Attack Pattern Enumeration and Classification

  • Collect Data from Common Resource Locations CAPEC-150 An adversary exploits well-known locations for resources for the purposes of undermining the security of the target. In many, if not most systems, files and resources are organized in a default tree structure. This can be useful for adversaries because they often know where to look for resources or files that are necessary for attacks. Even when the precise location of a targeted resource may not be known, naming conventions may indicate a small area of the target machine's file tree where the resources are typically located. For example, configuration files are normally stored in the /etc director on Unix systems. Adversaries can take advantage of this to commit other types of attacks.
  • Probe System Files CAPEC-639 An adversary obtains unauthorized information due to improperly protected files. If an application stores sensitive information in a file that is not protected by proper access control, then an adversary can access the file and search for sensitive information.
