CVSS v3.1

Official Description

GPT Academic run_in_subprocess_wrapper_func Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GPT Academic. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the run_in_subprocess_wrapper_func function. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-27958.

Risk Analysis

A critical deserialization vulnerability in the run_in_subprocess_wrapper_func function of GPT Academic allows unauthenticated remote attackers to execute arbitrary code as root. This flaw is highly dangerous given the lack of authentication.

No public exploit is known, and it is not in the CISA KEV. It is remotely exploitable with low complexity.

Recommended Action

Upgrade GPT Academic to a version beyond 3.91 to mitigate the deserialization risk.

Technical Analysis

CVE-2026-0763 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
