Summary
Harden input handling in
js-moera-api/jsmoeraapi.py(flagged by semgrep).Vulnerability
utils.custom.path-traversal-openjs-moera-api/jsmoeraapi.py:587Description: User-controlled input used in file path for open() without sanitization. This can allow path traversal attacks to read arbitrary files.
Threat Model Context
This is a web application - XSS and injection vulnerabilities can affect end users.
Changes
js-moera-api/jsmoeraapi.pyBehavior Preservation
The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.
