CVE-2026-33140 Details
Description
PySpector is a static analysis security testing (SAST) Framework engineered for modern Python development workflows. PySpector versions 0.1.6 and prior are affected by a stored Cross-Site Scripting (XSS) vulnerability in the HTML report generator. When PySpector scans a Python file containing JavaScript payloads (i.e. inside a string passed to eval() ), the flagged code snippet is interpolated into the HTML report without sanitization. Opening the generated report in a browser causes the embedded JavaScript to execute in the browser's local file context. This issue has been patched in version 0.1.7.
A stored Cross-Site Scripting vulnerability has been identified in PySpector versions through 0.1.6, specifically within the HTML report generator. This issue arises when PySpector scans Python files that contain JavaScript payloads, particularly those embedded in strings passed to the eval() function. The flagged code snippets are inserted into the HTML report without proper sanitization. As a result, when the report is opened in a browser, the embedded JavaScript executes in the context of the local file.
Users can upgrade to PySpector version 0.1.7, where this vulnerability has been patched.
