CVE-2026-33140 describes a stored Cross-Site Scripting (XSS) vulnerability affecting PySpector versions 0.1.6 and prior, a static analysis security testing (SAST) framework for Python. This medium-severity flaw (CVSS 6.1) allows malicious JavaScript embedded in a Python file to be unsafely included in PySpector's HTML reports. When a user opens such a report, the embedded script executes in their browser, potentially leading to information disclosure or unauthorized actions within the local file context. Exploitation requires user interaction to view the crafted report, and there is currently no evidence of active exploitation, public exploit code, or significant community discussion. Organizations using PySpector should upgrade to version 0.1.7 or later to remediate this vulnerability.
